The 1974 Atlantic hurricane season officially began on June 1, 1974, and lasted until November 30, 1974. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The season had near average activity, with eleven total storms and four hurricanes forming.
The most notable storms of the season were Hurricane Carmen, which made landfall on the Yucatán Peninsula and in Louisiana, causing at least $150 million (1974 US dollars) in damages; and Hurricane Fifi, which killed 8,000 people as it skimmed along the northern coast of Honduras. Hurricane Fifi crossed over into the eastern Pacific and was renamed Orlene.
The season's activity was reflected with a cumulative accumulated cyclone energy (ACE) rating of 61. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength.
On June 22, a tropical depression formed. The depression eventually became Subtropical Storm One on June 24. It remained weak and dissipated on June 26.
A tropical depression formed over the southwestern Gulf of Mexico on June 22. It was classified as Tropical Depression One. As the depression moved southwestward, convection began to fire well northeast of the center forming a new cyclone by June 24. Convection over the new system was poorly organized, and it became a subtropical depression late on June 24. It strengthened into a subtropical storm on June 25 with its winds far away from the center. It crossed Florida that day, but that night, it became more frontal in character. It lost what tropical characteristics it had on June 25.
Subtropical Storm One caused three drowning deaths and $10 million in damage ($42 million in 2005 USD) when it passed over central Florida. Tropical Depression One and Subtropical Storm One are actually the same storm, but JTWC classified them as 2 separate systems.
