⭐ Core Definition: 2012 Atlantic hurricane season

The 2012 Atlantic hurricane season was the final year in a string of three consecutive very active seasons since 2010, with 19 tropical storms. The 2012 season was also a costly one in terms of property damage, mostly due to Hurricane Sandy. The season officially began on June 1 and ended on November 30, dates that conventionally delimit the period during each year in which most tropical cyclones form in the Atlantic Ocean. However, Alberto, the first named system of the year, developed on May 19 – the earliest date of formation since Subtropical Storm Andrea in 2007. A second tropical cyclone, Beryl, developed later that month. This was the first occurrence of two pre-season named storms in the Atlantic basin since 1951. It moved ashore in North Florida on May 29 with winds of 65 mph (105 km/h), making it the strongest pre-season storm to make landfall in the Atlantic basin. This season marked the first time since 2009 where no tropical cyclones formed in July. Another record was set by Hurricane Nadine later in the season; the system became the fourth-longest-lived tropical cyclone ever recorded in the Atlantic, with a total duration of 22.25 days. The final storm to form, Tony, dissipated on October 25, and the season came to a close when Hurricane Sandy became extratropical on October 29.

Pre-season forecasts by the Colorado State University (CSU) called for a below average season, with 10 named storms, 4 hurricanes, and 2 major hurricanes. The National Oceanic and Atmospheric Administration (NOAA) issued its first outlook on May 24, predicting a total of 9–15 named storms, 4–8 hurricanes, and 1–3 major hurricanes; both agencies noted the possibility of an El Niño, which limits tropical cyclone activity. Following two pre-season storms, the CSU updated their forecast to 13 named storms, 5 hurricanes, and 2 major hurricanes, while the NOAA upped their forecast numbers to 12–17 named storms, 5–8 hurricanes, and 2–3 major hurricanes on August 9. Despite this, activity far surpassed the predictions.

2012 Atlantic hurricane season in the context of Hurricane Sandy

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.

2012 Atlantic hurricane season in the context of 2016 Atlantic hurricane season

The 2016 Atlantic hurricane season was the first above-average hurricane season since 2012, producing 15 named storms, 7 hurricanes and 4 major hurricanes. The season officially started on June 1 and ended on November 30, though the first storm, Hurricane Alex which formed in the Northeastern Atlantic, developed on January 12, being the first hurricane to develop in January since 1938. The final storm, Otto, crossed into the Eastern Pacific on November 25, a few days before the official end. Following Alex, Tropical Storm Bonnie brought flooding to South Carolina and portions of North Carolina. Tropical Storm Colin in early June brought minor flooding and wind damage to parts of the Southeastern United States, especially Florida. Hurricane Earl left 94 fatalities in the Dominican Republic and Mexico, 81 of which occurred in the latter. In early September, Hurricane Hermine, the first hurricane to make landfall in Florida since Hurricane Wilma in 2005, brought extensive coastal flooding damage especially to the Forgotten and Nature coasts of Florida. Hermine was responsible for five fatalities and about $550 million (2016 USD) in damage.

The strongest, costliest, and deadliest storm of the season was Hurricane Matthew, the southernmost Category 5 Atlantic hurricane on record and the first to reach that intensity since Felix in 2007, ending the longest streak of seasons without a hurricane of such intensity in the Satellite Era. With at least 603 deaths attributed to it, Matthew was the deadliest Atlantic hurricane since Stan of 2005. Furthermore, damage from Matthew is estimated to be at least $16.5 billion, making it the ninth costliest Atlantic hurricane on record at the time. Hurricane Nicole became the first major hurricane to directly impact Bermuda since Hurricane Fabian in 2003, leaving widespread but relatively moderate damage on the island. The final tropical cyclone of the season – Hurricane Otto – brought severe flooding to Central America in November, particularly in Costa Rica and Nicaragua. Otto left 23 deaths and about $190 million in damage. On November 25, the storm emerged into the Eastern Pacific basin, the first such occurrence since Hurricane Cesar–Douglas in 1996. Most of the season's tropical cyclones impacted land, and nine of those storms caused loss of life. Collectively, the storms left at least 736 fatalities and $17.49 billion in damage, making the season the costliest since 2012.

2012 Atlantic hurricane season in the context of Hurricane Jose (2017)

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.
