In late September, Tropical Storm Debbie developed in the northwestern Caribbean and moved slowly across the region, before later reaching the Gulf of Mexico.

The storm dissipated just offshore of Louisiana, which resulted in only minor impact along the Gulf Coast of the United States.

[7] Season activity began with the formation of an unnamed tropical storm over the southern Gulf of Mexico on June 13.

The latter developed on August 27 and eventually became the most intense tropical cyclone of the 1965 season, peaking as a Category 4 hurricane with maximum sustained winds of 140 mph (225 km/h) on September 2.

The low caused the detachment of a disturbance from the Intertropical Convergence Zone, which was located near the south coast of Guatemala.

Winds blew the roof off of two beach cottages on St. George Island, while tides sank or washed ashore several small boats.

The rains also left street flooding in the Inglewood neighborhood of Tallahassee, forcing the evacuation of two families.

[7] A weak circulation was noted by Television Infrared Observation Satellite (TIROS) near Cape Verde on August 16.

[8] Anna began losing tropical characteristics, and early on the following day, it transitioned into an extratropical storm while about halfway between the Azores and Greenland.

Early the next day, the depression intensified into Tropical Storm Betsy, shortly before striking Saint Martin and Anguilla.

The storm fluctuated between Category 2 and 3 as it headed southwestward and then westward over the next day, passing over or close to several Bahamian islands, including Great Abaco and Andros.

Betsy caused one fatality and approximately $14 million in damage in the island chain, mostly to agriculture and crops.

Water reached several feet in height in upper Florida Keys, inundating highways and the first floor of buildings.

Nearly all of the land south of Homestead Air Force Base and east of U.S. Route 1 was covered by water.

[7][13] A cold front moved eastward from North America into the western Atlantic Ocean on August 28.

The system attained gale-force winds a day later, and turned westward on September 6, steered by a building ridge to the north.

[14] On September 21, another flight into the storm recorded a minimum pressure of 974 mbar (28.8 inHg), the lowest in relation to Carol.

[16] The storm curved east-southeastward, weakened, and transitioned into an extratropical cyclone while located north of the Azores on September 30.

[7] Despite winds of only 30 mph (50 km/h), the Miami Weather Bureau prematurely named the depression Debbie at 1600 UTC on September 25.

[8] After emerging into the Gulf of Mexico early on September 26, the storm was described as "weaker than before", as the convective activity indicated no organization.

[8] After peaked at winds of 60 mph (95 km/h) late on September 28,[8] cooler and drier air caused the storm to weaken.

[7] Debbie was a minimal tropical storm by September 29 and made landfall in Port Fourchon, Louisiana, with winds of 40 mph (65 km/h) at 2000 UTC.

[8] Despite weakening significantly before landfall, Debbie brought heavy precipitation, especially in Mobile, Alabama, where a 24-hour rainfall record was broken after 16.85 in (428 mm) fell.

[7] As a result, it is estimated that the final tropical depression of the season at 1200 UTC on October 12, while located about midway between Cape Verde and the Leeward Islands.

Around 1200 UTC, Elena attained its peak intensity with maximum sustained winds of 110 mph (175 km/h) and a minimum barometric pressure of 977 mbar (28.9 inHg).

[22] An estimated 75% of crops in eastern Palm Beach County were lost, equivalent to approximately $4.5 million in damage.

[21] A cold front exited the east coast of the United States on November 22, and moved eastward.

The low gradually lost frontal characteristics and acquired a more symmetrical structure, becoming a tropical depression just north of Bermuda on September 24.

Curving northeastward, the depression transitioned into an extratropical cyclone on September 26 and a different cold front absorbed it by the next day.

It includes their name, duration, peak classification and intensities, areas affected, damage, and death totals.
