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.
