five seasons=1972, 1973, 1974, 1975, 1976 The 1974 Atlantic hurricane season officially began onJune 1 ,1974 , and lasted untilNovember 30 ,1974 . These dates conventionally delimit the period of each year when mosttropical cyclone s form in theAtlantic basin . The season had fairly average activity, with eleven total storms and four hurricanes forming; moresubtropical cyclone s formed this year than any other year on record, with a total of four.The most notable storms of the season were
Hurricane Carmen , which made landfall on theYucatán Peninsula and inLouisiana , causing at least $150 million (1974US dollars ) in damages; andHurricane Fifi , which killed 8,000 people as it skimmed along the northern coast ofHonduras .__TOC__

ubtropical Storm One
Infobox Hurricane Small
Basin=Atl
Type=subtropical
Formed=June 24
Dissipated=June 25
1-min winds=55
Pressure=1000A tropical depression formed over the southwesternGulf of Mexico onJune 22 . As the depression moved southwestward, convection began to fire well northeast of the center forming a new cyclone by the 24th. Convection over the new system was poorly organized, and it became a subtropical depression late on the 24th. It strengthened into a subtropical storm on the 25th with its winds far away from the center. It crossedFlorida that day, but that night, it became more frontal in character. It lost what tropical characteristics it had on the 25th.Subtropical Storm One caused three drowning deaths and $10 million in damage ($42 million in 2005
USD ) when it passed over central Florida.ubtropical Storm Two

Basin=Atl
Type=subtropical
Track=1974 Atlantic subtropical storm 2 track.png
Formed=July 16
Dissipated=July 19
1-min winds=45
Pressure=1006A convective area of cloudiness existed northeast of theBahamas in middle July in response to a stationary frontal boundary. A subtropical depression formed onJuly 16 , and it became Subtropical Storm Two on the 17th. As it moved northeastward it gradually became absorbed by a large extratropical low pressure system, with the system dissipating on the 20th.ubtropical Storm Three

Basin=Atl
Type=subtropical
Track=1974 Atlantic subtropical storm 3 track.png
Formed=August 12
Dissipated=August 15
1-min winds=50
Pressure=992Subtropical Storm Three formed from a frontal wave onAugust 10 , located 300 miles south ofCape Cod . The storm moved southeastward, followed by a north, then northeast motion. The storm reached its peak of 60 mph late in its life, just prior to being absorbed by a frontal boundary on the 15th.Tropical Storm Alma

Basin=Atl
Track=Alma 1974 track.png
Formed=August 12
Dissipated=August 15
1-min winds=50
Pressure=1007The tropical depression that became Tropical Storm Alma formed from anIntertropical Convergence Zone (ITCZ) disturbance onAugust 12 over the southern tropical Atlantic. It moved steadily westward, reaching a peak of 65 mph on the way. It crossed the island ofTrinidad , the southernmost track of a Trinidad hit since 1933. OnAugust 15 , it moved into northernVenezuela , and the high mountain tops destroyed the circulation.Hurricane Becky

Basin=Atl
Track=Becky 1974 track.png
Formed=August 26
Dissipated=September 2
1-min winds=100
Pressure=977Hurricane Becky formed from an area of showers and thunderstorms onAugust 26 , located to the southwest ofBermuda . It moved northeastward, where it reached its peak of 115 mph. As it approached unfavorable conditions, Becky fell apart, dissipating onSeptember 2 .Hurricane Carmen
Infobox Hurricane Small
Basin=Atl
Track=Carmen 1974 track.png
Formed=August 29
Dissipated=September 10
1-min winds=130
Pressure=928Hurricane Carmen developed from a tropical wave onAugust 29 , located 180 miles east ofGuadeloupe . It intensified at a steady rate, reaching tropical storm strength on the 30th and a hurricane on the 31st. As it approachedMexico , it strengthened to a 150 mph major hurricane, and made landfall nearChetumal as a Category 4 hurricane. A weakened Carmen moved through the Gulf, again reaching 150 mph winds prior to its southernLouisiana landfall onSeptember 7 , again as a Category 4 storm.Tropical Storm Dolly

Basin=Atl
Track=Dolly 1974 track.png
Formed=September 2
Dissipated=September 5
1-min winds=45
Pressure=1005Dolly developed from a cloud system over the central north Atlantic onSeptember 2 . The next day it became a tropical storm, but as the storm moved quickly to the northeast, it encountered cool, dry air, dissipating on the 5th.Tropical Storm Elaine
Infobox Hurricane Small
Basin=Atl
Track=Elaine 1974 track.png
Formed=September 4
Dissipated=September 13
1-min winds=60
Pressure=1001The tropical depression that became Tropical Storm Elaine formed from a tropical wave onSeptember 4 about 600 miles east of the Lesser Antilles. The depression moved northwestward for 5 days without strengthening, but on the 9th it moved under a favorable upper-level anticyclone, letting the depression strengthen to tropical storm strength. Elaine reached her peak of 70 mph under these favorable conditions, but as they became unfavorable, Elaine weakened, becoming extratropical on the 14th.Hurricane Fifi
Infobox Hurricane Small
Basin=Atl
Track=Fifi 1974 track.png
Formed=September 14
Dissipated=September 22
1-min winds=95
Pressure=971Hurricane Fifi formed from a tropical wave in the easternCaribbean Sea onSeptember 14 . As it moved westward to theCentral America n coast, its winds strengthened to 105 mph. It moved north of the coast ofHonduras , but warm moist air from the Caribbean and the easternPacific caused massive flooding. It hitBelize on the 19th, crossed Central America and Mexico, and re-emerged as Tropical Storm Orlene as part of the1974 Pacific hurricane season .Fifi caused an estimated 8,000 deaths.
Hurricane Gertrude
Infobox Hurricane Small
Basin=Atl
Track=Gertrude 1974 track.png
Formed=September 27
Dissipated=October 4
1-min winds=65
Pressure=999Hurricane Gertrude developed from anIntertropical Convergence Zone disturbance onSeptember 28 , located east of theLesser Antilles . As it approached the islands, it rapidly strengthened to a tropical storm late on the 28th, and to a hurricane six hours later. Prior to reaching the islands, the convection was sheared from the center, leaving behind a minimal tropical storm as it passed through theLesser Antilles onOctober 2 . The system dissipated on the 4th over the southeasternCaribbean Sea .ubtropical Storm Four
Infobox Hurricane Small
Basin=Atl
Type=subtropical
Formed=October 4
Dissipated=October 8
1-min winds=45
Pressure=1006The subtropical depression that became Subtropical Storm Four developed from a stationary cold front onOctober 4 near the east coast ofCuba . It moved northwestward, strengthening to subtropical storm force winds, and brushing the east coast of Florida. The storm moved out to sea, merging with a cold front on the 9th after becoming extratropical on the 8th.Accumulated Cyclone Energy (ACE) Rating
The table on the right shows the ACE for each storm in the season. The ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed for, so hurricanes that lasted a long time have higher ACEs.
