Tropical wave in the context of Intertropical Convergence Zone

Hurricane Harvey was a powerful and devastating tropical cyclone that made landfall in Texas and Louisiana in August 2017, causing catastrophic flooding and more than 100 deaths. It is tied with 2005's Hurricane Katrina as the costliest tropical cyclone on record, inflicting $125 billion (2017 USD) in damage, primarily from catastrophic rainfall-triggered flooding in Greater Houston and Southeast Texas; this made the storm the costliest natural disaster recorded in Texas at the time. It was the first major hurricane to make landfall in the United States since Wilma in 2005, ending a record 12-year span in which no hurricanes made landfall at the intensity of a major hurricane throughout the country. In a four-day period, many areas received more than 40 inches (1,000 mm) of rain as the system slowly meandered over eastern Texas and adjacent waters, causing unprecedented flooding. With peak accumulations of 60.58 in (1,539 mm) in Nederland, Texas, Harvey was the wettest tropical cyclone on record in the United States. The resulting floods inundated hundreds of thousands of homes, which displaced more than 30,000 people and prompted more than 17,000 rescues.

The eighth named storm, third hurricane, and first major hurricane of the extremely active 2017 Atlantic hurricane season, Harvey developed from a tropical wave to the east of the Lesser Antilles, reaching tropical storm status on August 17. The storm crossed through the Windward Islands on the following day, making landfall on the southern end of Barbados and a second landfall on Saint Vincent. Upon entering the Caribbean, Harvey began to weaken due to moderate wind shear, and degenerated into a tropical wave north of Colombia, late on August 19. The remnants were monitored for regeneration as it continued west-northwestward across the Caribbean and the Yucatán Peninsula, before redeveloping over the Bay of Campeche on August 23. Harvey then began to rapidly intensify on August 24, regaining tropical storm status and becoming a hurricane later that day.

Hurricane Sandy (unofficially referred to as Superstorm Sandy) was an extremely large and devastating tropical cyclone which ravaged the Caribbean and the coastal Mid-Atlantic region of the United States in late October 2012. It was the largest Atlantic hurricane on record as measured by diameter, with tropical-storm-force winds spanning 1,150 miles (1,850 km). The storm inflicted nearly US$70 billion in damage (equivalent to $96 billion in 2024), and killed 254 people in eight countries, from the Caribbean to Canada. The eighteenth named storm, tenth hurricane, and second major hurricane of the 2012 Atlantic hurricane season, Sandy was a Category 3 storm at its peak intensity when it made landfall in Cuba, though most of the damage it caused was after it became a Category 1-equivalent extratropical cyclone off the coast of the Northeastern United States.

Sandy developed from a tropical wave in the western Caribbean Sea on October 22, quickly strengthened, and was upgraded to Tropical Storm Sandy six hours later. Sandy moved slowly northward toward the Greater Antilles and gradually intensified. On October 24, Sandy became a hurricane, made landfall near Kingston, Jamaica, re-emerged a few hours later into the Caribbean Sea and strengthened into a Category 2 hurricane. On October 25, Sandy hit Cuba as a Category 3 hurricane, then weakened to a Category 1 hurricane. Early on October 26, Sandy moved through the Bahamas. On October 27, Sandy briefly weakened to a tropical storm and then strengthened back to a Category 1 hurricane. Early on October 29, Sandy curved west-northwest (the "left turn" or "left hook") and then moved ashore near Brigantine, New Jersey, just to the northeast of Atlantic City, as a post-tropical cyclone with hurricane-force winds. Sandy continued drifting inland for another few days while gradually weakening, until it was absorbed by another approaching extratropical storm on November 2.

Hurricane Marie is tied as the seventh-most intense Pacific hurricane on record, attaining a barometric pressure of 918 mbar (hPa; 27.11 inHg) in August 2014. The fourteenth named storm, ninth hurricane, and sixth major hurricane of the season, Marie began as a tropical wave that emerged off the west coast of Africa over the Atlantic Ocean on August 10. Some organization of shower and thunderstorm activity initially took place, but dry air soon impinged upon the system and imparted weakening. The wave tracked westward across the Atlantic and Caribbean for several days. On August 19, an area of low pressure consolidated within the wave west of Central America. With favorable atmospheric conditions, convective activity and banding features increased around the system and by August 22, the system acquired enough organization to be classified as Tropical Depression Thirteen-E while situated about 370 mi (595 km) south-southeast of Acapulco, Mexico. Development was initially fast-paced, as the depression acquired tropical storm-force winds within six hours of formation and hurricane-force by August 23. However, due to some vertical wind shear its intensification rate stalled, and for a time it remained a Category 1 hurricane on the Saffir–Simpson hurricane wind scale.

On August 24, Marie developed an eye and rapidly intensified to a Category 5 hurricane with winds of 160 mph (260 km/h). At its peak, the hurricane's gale-force winds spanned an area 575 mi (925 km) across. Marie subsequently underwent an eyewall replacement cycle on August 25 which prompted steady weakening. Over the next several days, Marie progressively degraded to below hurricane strength as it moved into an increasingly hostile environment with cooler waters and a more stable atmosphere. On August 29, after having lost all signs of organized deep convection, Marie degenerated into a remnant low. The large system gradually wound down over the following several days, with winds subsiding below gale-force on August 30. The remnant cyclone eventually lost a well defined center and dissipated on September 2 about 1,200 mi (1,950 km) northeast of Hawaii.

Hurricane Florence was a powerful and long-lived tropical cyclone that caused catastrophic damage in the Carolinas in September 2018, primarily as a result of freshwater flooding due to torrential rain. The sixth named storm, third hurricane, and the first major hurricane of the 2018 Atlantic hurricane season, Florence originated from a strong tropical wave that emerged off the west coast of Africa on August 30, 2018. The wave steadily organized, and strengthened into a tropical depression on the next day near Cape Verde. Progressing along a steady west-northwest trajectory, the system gradually strengthened, acquiring tropical storm strength on September 1. An unexpected bout of rapid intensification ensued on September 4–5, culminating with Florence becoming a Category 4 major hurricane on the Saffir–Simpson scale (SSHWS), with estimated maximum sustained winds of 130 mph (215 km/h). Strong wind shear then led to rapid weakening, and Florence weakened to tropical storm strength on September 7. Shifting steering currents led to a westward turn into a more suitable environment; as a result, Florence reintensified to hurricane strength on September 9 and major hurricane status by the following day. Florence reached peak intensity on September 11, with 1-minute winds of 150 mph (240 km/h) and a minimum central pressure of 937 mbar (27.7 inHg). An unexpected eyewall replacement cycle and decreasing oceanic heat content caused a steady weakening trend; however, the storm grew in size at the same time. Early on September 14, Florence made landfall in the United States just south of Wrightsville Beach, North Carolina as a Category 1 hurricane, and weakened further as it slowly moved inland under the influence of weak steering currents. Florence degenerated into a post-tropical cyclone over West Virginia on September 17 and was absorbed by another frontal storm two days later.

Early in the storm's history, the system brought squalls to the Cape Verde islands, resulting in minor landslides and flooding; however, overall effects remained negligible. With the threat of a major impact in the Southeastern and Mid-Atlantic United States becoming evident by September 7, the governors of North Carolina, South Carolina, Virginia, Georgia, and Maryland, and the mayor of Washington, D.C. declared a state of emergency. On September 10 and 11, the states of North Carolina, South Carolina, and Virginia issued mandatory evacuation orders for some of their coastal communities, predicting that emergency personnel would be unable to reach people there once the storm arrived. Though Florence made landfall as a greatly weakened Category 1 hurricane, winds associated with the tropical cyclone were strong enough to uproot trees and power lines, causing extensive power outages across the Carolinas. Furthermore, due to the slow motion of the storm, heavy rain fell throughout the Carolinas for several days. Coupled with a powerful storm surge, the rainfall caused widespread flooding along a long stretch of the North Carolina coast, from New Bern to Wilmington. Inland flooding from Florence inundated cities such as Fayetteville, Smithfield, Lumberton, Durham, and Chapel Hill. Most major roads and highways in the area experienced flooding, with large stretches of I-40, I-95, and US Route 70 remaining impassable for days after the storm's passage. Wilmington was cut off entirely from the rest of the mainland by the flooding. The storm also spawned tornadoes in several places along its path, including an EF2 tornado that killed one person in Virginia. Many places received record-breaking rainfall, with Florence setting maximum rainfall records from a tropical cyclone in both of the Carolinas. Overall, the storm caused $24.23 billion in damage, mostly in the Carolinas, and 54 deaths.

The African easterly jet is a region of the lower troposphere over West Africa where the seasonal mean wind speed is at a maximum and the wind is easterly. The temperature contrast between the Sahara Desert and the Gulf of Guinea causes the jet to form to the north of the monsoon trough. The jet's maximum wind speeds are at a height of 3 kilometres (1.9 mi). The jet moves northward from its south-most location in January, reaching its most northerly latitude in August. Its strongest winds are in September while it begins shifting back towards the equator. Within the easterly jet, tropical waves form. Convective complexes associated with these waves can form tropical cyclones. If the jet is south of its normal location during August and September, tropical cyclogenesis is suppressed. If desertification continues across Sub-Saharan Africa, the strength of the jet could increase, although tropical wave generation probably would decrease, which would decrease the number of tropical cyclones in the Atlantic basin.

Hurricane Irma was an extremely powerful and devastating tropical cyclone that caused extensive damage and loss of life across the Antilles and Eastern United States in September 2017. Irma was the first Category 5 hurricane to strike the Leeward Islands on record, though it was followed by Hurricane Maria, which struck the region at Category 5 intensity as well two weeks later. At the time, Irma was considered the most powerful hurricane on record in the open Atlantic region, outside of the Caribbean Sea and Gulf of Mexico, until it was surpassed by Hurricane Dorian two years later. It was also the third-strongest Atlantic hurricane at landfall ever recorded, just behind the 1935 Labor Day hurricane, Hurricane Melissa, and Dorian.

The ninth named storm, fourth hurricane, second major hurricane, and first Category 5 hurricane of the extremely active 2017 Atlantic hurricane season, Irma developed from a tropical wave near the Cape Verde Islands on August 30. Favorable conditions allowed Irma to rapidly intensify into a Category 3 hurricane on the Saffir–Simpson wind scale by late on August 31. The storm's intensity fluctuated between Categories 2 and 3 for the next several days, due to a series of eyewall replacement cycles. On September 4, Irma resumed intensifying, becoming a Category 5 hurricane by early on the next day. Early on September 6, Irma peaked with 1-minute sustained winds of 180 mph (290 km/h) and a minimum pressure of 914 hPa (27.0 inHg). Irma was the second-most intense tropical cyclone worldwide in 2017 in terms of barometric pressure, and the strongest worldwide in 2017 in terms of wind speed. Another eyewall replacement cycle caused Irma to weaken back to a Category 4 hurricane, but the storm re-attained Category 5 status before making landfall in Cuba. Although Irma briefly weakened to a Category 2 storm while making landfall on Cuba, the system re-intensified to Category 4 status as it crossed the warm waters of the Straits of Florida, before making landfall on Cudjoe Key on September 10. Irma then weakened to Category 3 status, prior to another landfall in Florida on Marco Island later that day. The system degraded into a remnant low over Alabama and ultimately dissipated on September 13 over Missouri.

Hurricane Ike (/aɪk/) was a long-lived, powerful and destructive tropical cyclone that swept through portions of the Greater Antilles and Northern America in September 2008, wreaking havoc on infrastructure and agriculture, particularly in Cuba and Texas. Ike took a similar track to the 1900 Galveston hurricane. The ninth tropical storm, fifth hurricane, and third major hurricane of the 2008 Atlantic hurricane season, Ike developed from a tropical wave west of Cape Verde on September 1 and strengthened to peak intensity as a Category 4 hurricane over the open waters of the central Atlantic on September 4 as it tracked westward. Several fluctuations in strength occurred before Ike made landfall on eastern Cuba on September 8. The hurricane weakened prior to continuing into the Gulf of Mexico, but increased its intensity by the time of its final landfall in Galveston, Texas, on September 13 before becoming an extratropical storm on September 14. The remnants of Ike continued to track across the United States and into Canada, causing considerable damage inland, before dissipating on the next day.

Ike was blamed for at least 195 deaths. Of these deaths, 74 were in Haiti, which was already trying to recover from the impact of three storms (Fay, Gustav, and Hanna) that had made landfall the same year. Seven people were killed in Cuba. In the United States, 113 people were reported killed, directly or indirectly, and 16 were still missing as of August 2011. Due to its immense size, Ike caused devastation from the Louisiana coastline all the way to the Kenedy County region near Corpus Christi, Texas. In addition, Ike caused flooding and significant damage along the Mississippi coastline and the Florida Panhandle. Damages from Ike in U.S. coastal and inland areas are estimated at $30 billion (2008 USD), with additional damage of $7.3 billion in Cuba, $200 million in the Bahamas, and $500 million in the Turks and Caicos, amounting to a total of at least $38 billion in damage. At the time, the hurricane was the second-costliest in United States history. The search-and-rescue operation after Ike was the largest search-and-rescue operation in Texas history.

A Hovmöller diagram is a common way of plotting meteorological data to highlight the behavior of waves, particularly tropical waves. The axes of Hovmöller diagrams depict changes over time of scalar quantities such as temperature, density, and other values of constituents in the atmosphere or ocean, such as depth, height, or pressure. Typically in that case, time is recorded along the abscissa, or x-axis, while 'vertical' values (of depth, height, pressure, etc.) are plotted along the ordinate, or y-axis.

The alternate orientation of axes may also be used, as a Hovmöller diagram may be plotted for longitude or latitude on the abscissa and for (advancing) time on the ordinate; then the contour values of a named physical field may be presented through color or shading.

Hurricane Maria was an extremely powerful and catastrophic tropical cyclone that affected the northeastern Caribbean in September 2017, particularly in the U.S. territory of Puerto Rico, which accounted for 2,975 of the 3,059 deaths. It is the deadliest and costliest hurricane to strike the archipelago and island of Puerto Rico, and is the deadliest hurricane to strike the country of Dominica and the territory of the U.S. Virgin Islands. The most intense tropical cyclone worldwide in 2017, Maria was the thirteenth named storm, eighth consecutive hurricane, fourth major hurricane, second Category 5 hurricane, and deadliest storm of the extremely active 2017 Atlantic hurricane season. With over 3,000 deaths and a minimum central pressure of 908 millibars (26.8 inHg), Maria was the twelfth most intense Atlantic hurricane on record, respectively. Total monetary losses are estimated at upwards of $91.61 billion (2017 USD), almost all of which came from Puerto Rico, ranking it as the fourth-costliest tropical cyclone on record.

Maria developed from a tropical wave on September 16 east of the Lesser Antilles. Steady strengthening and organization took place initially, until favorable conditions enabled it to undergo explosive intensification on the afternoon of September 18, achieving Category 5 strength just before making landfall on the island of Dominica that night. After crossing the island and weakening slightly, Maria re-intensified and achieved its peak intensity with maximum sustained winds of 175 mph (280 km/h) and a pressure of 908 mbar (hPa; 26.81 inHg). On September 20, an eyewall replacement cycle weakened Maria to a high-end Category 4 hurricane by the time it struck Puerto Rico. The hurricane re-emerged weaker from land interaction, but quickly restrengthened back into a major hurricane again the following day. Passing north of The Bahamas, Maria remained a powerful hurricane over the following week as it slowly paralleled the East Coast of the United States, gradually weakening over time as conditions became less favorable. Maria then stalled and swung eastward over the open Atlantic, becoming extratropical on September 30 before dissipating by October 2.

Hurricane Emily was the first July Atlantic hurricane to reach Category 5 status on the Saffir-Simpson scale. It remained the only to have done so until Beryl of 2024. The fifth named storm, third hurricane, second major hurricane, and first Category 5 hurricane of the record-breaking 2005 Atlantic hurricane season, Emily formed on July 11 from a tropical wave east of the Lesser Antilles. Three days later, it made landfall on Grenada as a minimal hurricane, just ten months after Hurricane Ivan devastated the region. Emily attained maximum sustained winds of 260 km/h (160 mph) on July 16 while passing southwest of Jamaica, which at the time made it the strongest Atlantic hurricane before the month of August. Slight weakening occurred before Emily made landfall along Mexico's Yucatán Peninsula on July 18 as a Category 4 hurricane. Quickly crossing the peninsula, Emily emerged over the Gulf of Mexico as a minimal hurricane. It reorganized and reached Category 3 intensity before making its final landfall in the Mexican state of Tamaulipas on July 20. It rapidly weakened and dissipated over land on July 21, although thunderstorms reached as far inland as New Mexico. In 2024, Emily was surpassed by Hurricane Beryl as the strongest Atlantic hurricane before August, as measured by maximum sustained winds.

Emily was a powerful early-season tropical cyclone that caused significant damage across the Lesser Antilles, the Caribbean, and Mexico. While moving through the Lesser Antilles, the hurricane produced strong winds and heavy rainfall that caused flooding and landslides across several islands. In Grenada, a man died when a landslide destroyed his house. The hurricane damaged or destroyed 2,641 homes in the country, leaving 167 families homeless. Emily's damage on Grenada totaled EC$121.14 million (US$44.87 million). Later, the hurricane dropped 392 mm (15.43 in) of rainfall on Jamaica, which added to the destruction caused by Hurricane Dennis a week earlier. Damage from the two hurricanes totaled J$5.98 billion (US$96 million) in Jamaica. Also in the country, five people died related to a vehicle accident and floods. In nearby Haiti, flooding from Emily caused ten fatalities. Emily's impacts occurred as far south as Honduras, where one person drowned due to river flooding from the storm.

Hurricane Rita is the most intense tropical cyclone on record in the Gulf of Mexico, now tied with Hurricane Milton of 2024, as well as being one of the most intense Atlantic hurricanes on record overall. Part of the record-breaking 2005 Atlantic hurricane season, which included three of the ten most intense Atlantic hurricanes in terms of barometric pressure ever recorded (along with Wilma and Katrina), Rita was the seventeenth named storm, tenth hurricane, fifth major hurricane, and third Category 5 hurricane of the 2005 season. It was also the earliest-forming 17th named storm in the Atlantic until Tropical Storm Rene in 2020. Rita formed near The Bahamas from a tropical wave on September 18, 2005, that originally developed off the coast of West Africa. It moved westward, and after passing through the Florida Straits, Rita entered an environment of abnormally warm waters. Moving west-northwest, it rapidly intensified to reach peak winds of 180 mph (285 km/h), achieving Category 5 status on September 21. However, it weakened to a Category 3 hurricane before making landfall in Johnson's Bayou, Louisiana, between Sabine Pass, Texas and Holly Beach, Louisiana, with winds of 115 mph (185 km/h). Rapidly weakening over land, Rita degenerated into a large low-pressure area over the lower Mississippi Valley by September 26.

In Louisiana, Rita's storm surge inundated low-lying communities along the entire coast, worsening effects caused by Hurricane Katrina less than a month prior, such as topping the hurriedly-repaired Katrina-damaged levees at New Orleans. Parishes in Southwest Louisiana and counties in Southeast Texas where Rita made landfall suffered from severe to catastrophic flooding and wind damage. According to an October 25, 2005, Disaster Center report, 4,526 single-family dwellings were destroyed in Orange and Jefferson counties located in Southeast Texas. Major damage was sustained by 14,256 additional single-family dwellings, and another 26,211 single-family dwellings received minor damage. Mobile homes and apartments also sustained significant damage or total destruction. In all, nine Texas counties and five Louisiana Parishes were declared disaster areas after the storm. Electric service was disrupted in some areas of both Texas and Louisiana for several weeks. Texas reported the most deaths from the hurricane, where 113 deaths were reported, 107 of which were associated with the evacuation of the Houston metropolitan area.

Hurricane Beryl (/ˈbɛrɪl/, BEHR-ril) was an extremely rare and destructive tropical cyclone that impacted parts of the Caribbean, the Yucatán Peninsula, and the Gulf Coast of the United States in late June and early July 2024. The second named storm, first hurricane, first major hurricane, and first Category 5 hurricane of the extremely active 2024 Atlantic hurricane season, the system broke many meteorological records, primarily for formation and intensity. Beryl was one of only two Atlantic hurricanes to reach Category 5 hurricane status in July, along with Emily in 2005. Beryl was both the earliest-forming Category 4 and Category 5 hurricane on record in the Atlantic Ocean, and the strongest hurricane to develop within the Main Development Region (MDR) of the Atlantic before the month of July.

Beryl developed from a tropical wave that left the coast of Africa on June 25. After forming on June 28 in the Main Development Region, it began rapidly intensifying as it moved west through the central tropical Atlantic. On July 1, Beryl made landfall on the island of Carriacou, Grenada, as a Category 4 hurricane, causing significant damage. The hurricane intensified further as it entered the Caribbean Sea, peaking as a Category 5 hurricane early the next morning with maximum sustained winds of 165 mph (270 km/h) and a minimum central pressure of 932 mbar (27.52 inHg), before slowly weakening over the next few days due to wind shear as it passed south of Jamaica and then the Cayman Islands. It briefly re-intensified into a Category 3 hurricane before weakening again as it made landfall in Tulum, Quintana Roo, as a high-end Category 1 hurricane on July 5. After weakening into a tropical storm over the Yucatán Peninsula, the system moved into the Gulf of Mexico, where it gradually reorganized into a Category 1 hurricane on July 8, just before making its final landfall near Matagorda, Texas. Beryl slowly weakened over land as it accelerated to the northeast, eventually becoming post-tropical over the state of Arkansas on July 9 and dissipating over Ontario on July 11.

Tropical Storm Claudette was a 1979 tropical cyclone which was the third-wettest tropical cyclone on record in the contiguous United States. The storm caused significant flooding in eastern Texas and western Louisiana in July 1979. The eighth tropical cyclone and third named storm of the 1979 Atlantic hurricane season, Claudette developed from a tropical wave located east of the Windward Islands on July 16. It gradually strengthened and was upgraded to a tropical storm on July 17 and crossed the northern Leeward Islands later that day. As it neared landfall in Puerto Rico early on July 18, upper-level winds weakened it back to a tropical depression. Claudette remained disorganized and the National Hurricane Center operationally reported that it degenerated back into a tropical wave after crossing Puerto Rico. Late on July 18, the depression struck Dominican Republic, emerged into the Caribbean Sea on the following day. Claudette struck western Cuba on July 21, shortly before reaching the Gulf of Mexico and "regenerating" into a tropical cyclone. By July 23, Claudette regained tropical storm intensity and turned northward toward the Gulf Coast of the United States. The storm made landfall near the Texas-Louisiana border late on July 23 as a moderately strong tropical storm. It weakened slowly and drifted over land, lasting until dissipation in West Virginia on July 29.

In the Lesser Antilles, the storm brought heavy rainfall and gusty winds to several islands. Minor flooding occurred in Guadeloupe and Saint Croix. Rainfall exceeding 10 inches (250 mm) in some areas of Puerto Rico led to widespread agricultural damage, flooded homes and streets, and one fatality; losses were estimated at $750,000 (1979 USD). Despite its passage over Hispaniola and Cuba, impact in both regions is unknown. Claudette brought record-breaking rainfall to eastern Texas. In Alvin, 42 inches (1,100 mm) of rain fell in one day, which at one point was the record 24‑hour precipitation amount for any location in the United States. Significant coastal flooding and up to 15 inches (380 mm) of rainfall was reported in Louisiana. Overall, Claudette was responsible for two deaths and $400 million (1979 USD) in damage.

Hurricane Jose was a powerful, erratic, and long-lived tropical cyclone, the longest-lived since Hurricane Nadine in 2012. Jose was the tenth named storm, fifth hurricane, and third major hurricane of the 2017 Atlantic hurricane season. Jose developed into a tropical storm on September 5 from a tropical wave that left the west coast of Africa nearly a week prior. A period of rapid intensification ensued on September 6, when Jose reached hurricane intensity. On September 8, it reached its peak intensity as a high-end Category 4 with 1-minute sustained winds of 155 mph. However, due to wind shear, it weakened over the next few days as it completed an anti-cyclonic loop north of Hispaniola. Despite weakening to a tropical storm on September 14, Jose managed to regain hurricane intensity the next day as it began to curve northward. Never strengthening above Category 1 status for the remainder of its lifespan, Jose degraded to a tropical storm once again on September 20. Two days later, Jose degenerated into a post-tropical cyclone as it drifted northeastwards off the coast of New England. By September 26, Jose's remnants had dissipated off the East Coast of the United States.

Initially projected to impact the Antilles already affected by Hurricane Irma, Jose triggered evacuations in catastrophically damaged Barbuda, as well as in Saint Martin. Eventually, as Jose changed its path, its inner core and thus the strongest winds stayed offshore. Nonetheless, Jose still brought tropical storm-force winds to those islands. Later on, Jose brought heavy rain, swells, and rough surf to the East Coast of the United States, causing beach erosion and some flooding. A woman died after she was caught in a rip current in Asbury Park, New Jersey.

Hurricane Dorian was an extremely powerful and catastrophic tropical cyclone, which became the most intense on record to strike the Bahamas. It is tied with the 1935 Labor Day hurricane and Hurricane Melissa in 2025 for the strongest landfall in the Atlantic basin in terms of maximum sustained winds. It is regarded as the worst natural disaster in the Bahamas' recorded history. With winds peaking at 185 mph (295 km/h), it was also one of the most powerful hurricanes recorded in the Atlantic Ocean in terms of 1-minute sustained winds, and the strongest since Wilma in 2005. Dorian was the fourth named storm, second hurricane, the first major hurricane, and the first Category 5 hurricane of the 2019 Atlantic hurricane season. Dorian struck the Abaco Islands on September 1 with maximum sustained winds of 185 mph (295 km/h), tying with the 1935 Labor Day hurricane and Melissa for the highest wind speeds of an Atlantic hurricane ever recorded at landfall. Dorian went on to strike Grand Bahama at similar intensity, stalling just north of the territory with unrelenting winds for at least 24 hours. The resultant damage to these islands was catastrophic; most structures were flattened or swept to sea, and at least 70,000 people were left homeless. After it ravaged through The Bahamas, Dorian proceeded along the coasts of the Southeastern United States and Atlantic Canada, leaving behind considerable damage and economic losses in those regions.

Dorian developed from a tropical wave on August 24 over the Central Atlantic. The storm moved through the Lesser Antilles and became a hurricane north of the Greater Antilles on August 28. Dorian proceeded to undergo rapid intensification over the following days, before reaching its peak as a Category 5 hurricane with one-minute sustained winds of 185 mph (295 km/h) and a minimum central pressure of 910 millibars (26.87 inHg) by September 1. It made landfall in The Bahamas in Elbow Cay, just east of Abaco Island, and again on Grand Bahama several hours later, where it remained nearly stationary for the next day or so. After weakening considerably, Dorian began moving northwestward on September 3, parallel to the east coast of Florida. Dwindling in strength, the hurricane turned to the northeast the next day and made landfall on Cape Hatteras at Category 2 intensity on September 6. Dorian transitioned into an extratropical cyclone on September 7, before striking first Nova Scotia and then Newfoundland with hurricane-force winds on the next day. The storm finally dissipated near Greenland on September 10.

Hurricane Jova was a very powerful tropical cyclone that became the first Pacific hurricane to reach Category 5 strength on the Saffir-Simpson scale since Willa in 2018. Jova was also one of the fastest–intensifying tropical cyclones on record in the Eastern Pacific tropical cyclone basin. The tenth named storm, seventh hurricane, and fifth major hurricane of the 2023 Pacific hurricane season, Jova originated from a tropical wave that entered the Pacific Ocean on September 1. The system rapidly organized and became a tropical depression the following day. After brief inhibition by wind shear, The system explosively organized over the next two days. It formed a prominent in its central dense overcast on September 5 and nascent eye feature, Signaling its intensification into a hurricane. In a 24-hour period ending early on September 7, Jova's maximum sustained winds significantly increased from 90 mph (150 km/h) to its peak at 160 mph (260 km/h) and its central pressure fell 67 mbar (hPa; 1.89 inHg) to its minimum of 926 mbar (hPa; 27.43 inHg). This made it a Category 5 hurricane and was one of the five-fastest periods of intensification on record in the basin. Thereafter, an eyewall replacement cycle commenced. and decreasing sea surface temperatures caused the storm to gradually weaken, It fell below major hurricane status on September 8 and further weakened to a tropical storm on September 9. The total collapse of convection on September 10 marked its degeneration into a remnant low. The system later dissipated on September 12 as it opened up into a trough.

Jova's expansive cloud shield led to some rainfall in western states of Mexico with minor flooding occurring in Baja California Sur. Large waves and rip currents affected coastal areas from Sinaloa northward to the San Francisco Bay Area in California. Flooding in Arizona inflicted $250,000 in damage.

Hurricane Fifi, later known as Hurricane Orlene, was a catastrophic tropical cyclone that killed over 8,000 people in Honduras in September 1974, ranking it as the third deadliest Atlantic hurricane on record, only behind Hurricane Mitch in 1998, and the 1780 hurricane. Fifi is also the first billion-dollar hurricane not to make landfall in the United States. Originating from a strong tropical wave on September 14, the system steadily tracked west-northwestward through the eastern Caribbean. On September 16, the depression intensified into Tropical Storm Fifi just off the coast of Jamaica. The storm quickly intensified into a hurricane the following afternoon and attained its peak intensity on September 18 as a strong Category 2 hurricane. Maintaining hurricane intensity, Fifi brushed the northern coast of Honduras before making landfall in Belize the following day. The storm quickly weakened after landfall, becoming a depression late on September 20. Continuing westward, the former hurricane began to interact with another system in the eastern Pacific.

Early on September 22, Fifi re-attained tropical storm status before fully regenerating into a new tropical cyclone, Tropical Storm Orlene. Orlene traveled in an arced path toward Mexico while quickly intensifying into a Category 2 hurricane before landfall. The storm weakened after landfall and dissipated fully during the afternoon of September 24 over the mountains of Mexico. Along its path, Fifi impacted nine countries, leaving over 8,200 fatalities and $1.8 billion (1974 USD; $11.5 billion 2025 USD) in damages. Most of the loss of life and damage occurred in Honduras where rainfall from the hurricane, peaking around 24 in (610 mm), triggered widespread flash flooding and mudslides.

Hurricane Janet was the most powerful tropical cyclone of the 1955 Atlantic hurricane season and one of the strongest Atlantic hurricanes on record. Janet was also the first named storm to cause 1,000 deaths and the first Category 5 storm name to be retired. The eleventh tropical storm, ninth hurricane, and fourth major hurricane of the year, Janet formed from a tropical wave east of the Lesser Antilles on September 21. Moving westward across the Caribbean Sea, Janet fluctuated in intensity, but generally strengthened before reaching its peak intensity as a Category 5 hurricane with winds of 175 mph (282 km/h). The intense hurricane later made landfall at that intensity near Chetumal, Mexico on September 28. After weakening over the Yucatán Peninsula, it moved into the Bay of Campeche, where it slightly strengthened before making its final landfall near Veracruz on September 29. Janet quickly weakened over Mexico's mountainous terrain before dissipating on September 30.

In its developmental stages, Janet caused $7.8 million in damage to the Lesser Antilles and 189 deaths in the Grenadines and Barbados. While Janet was in the central Caribbean Sea, a reconnaissance aircraft flew into the storm and was lost with all hands. This remains the only such loss which has occurred in association with an Atlantic hurricane. A Category 5 upon landfall on the Yucatán Peninsula, Janet caused severe devastation in areas of Quintana Roo and British Honduras. Only five buildings in Chetumal, Mexico remained intact after the storm, and an estimated 500 deaths occurred in the Mexican state of Quintana Roo. At Janet's second landfall near Veracruz, significant river flooding ensued, worsening effects caused by Hurricanes Gladys and Hilda earlier in the month. The floods left thousands of people stranded and killed at least 326 people in the Tampico area, leading to the largest Mexican relief operation ever executed by the United States.

Hurricane Bertha was the longest-lived Atlantic tropical cyclone on record during July, as well as the furthest east system to attain tropical storm intensity during the month. The second named storm, first hurricane, and first major hurricane of the active 2008 season, Bertha developed into a tropical depression on July 3 from a tropical wave that departed western Africa two days prior. On a west-northwest to northwest track, the depression intensified into Tropical Storm Bertha six hours formation and ultimately attained hurricane intensity on July 7. A period of rapid deepening brought the cyclone to its peak as a Category 3 hurricane with winds of 125 mph (205 km/h) late that afternoon. Changes in wind shear and the storm's internal structure allowed Bertha to fluctuate in intensity over the next week as it passed very near Bermuda, but a track over cooler waters eventually caused the system to become an extratropical cyclone by July 20. It continued northeast and was absorbed by another low near Iceland the following day. Rough surf propelled by Bertha killed three people along the East Coast of the United States; hundreds of other swimmers were injured and/or required rescuing. In Bermuda, some streets were flooded and strong gusts cut power to approximately 7,500 homes; only minor damage was observed.
