1965 Atlantic hurricane season
Encyclopedia
The 1965 Atlantic hurricane season officially began on June 1, 1965, and lasted until November 30, 1965. These dates conventionally delimit the period of each year when most tropical cyclone

on September 9, 1965 as a Category 4 hurricane. The eye passed to the southwest of New Orleans, though the eyewall covered much of southeast Louisiana for an eight-hour period. Betsy caused $10–$12 billion (2005 USD) in damage, as well as 76 deaths. It was the first storm to cause $1 billion US in damage (unadjusted for inflation), thus earning it the nickname "Billion Dollar Betsy".
for five days, maintaining hurricane force winds throughout. After looping, Carol turned to the northeast, reaching a peak of 100 mph (160 km/h) before weakening. It passed north of the Azores, turned to the southeast, and became extratropical west of Spain

Tropical cyclone
A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. Tropical cyclones strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor...

Hurricane Carol
Hurricane Carol developed on September 16 in the eastern Atlantic from a tropical wave that moved off the coast of Africa. The tropical depression moved quickly westward, becoming a tropical storm on September 17. The fast motion impeded development for the next few days, but as it slowed down, it was able to become a hurricane on September 20. Carol continued northward for the next three days, when it stalled west-southwest of the AzoresAzores

Hurricane Elena
A very weak circulation caused by a tropical wave moved across the tropical Atlantic. It became a tropical depression on October 12, though it had little, if any, convection near the center. It slowed as it moved to the northwest, becoming a tropical storm on October 14. Elena continued to organize, and reached hurricane force strength on the October 16 while recurving out to sea. The hurricane reached a peak of 80 mph (130 km/h) before becoming extratropical over the northern Atlantic on the October 19.Storm names
The following names were used for named storms (tropical storms and hurricanes) that formed in the North Atlantic in 1965. A storm was named Elena for the first time in 1965. Names that were not assigned are marked in .
