1780 Atlantic hurricane season
The 1780 Atlantic hurricane season was extraordinarily destructive, and was the deadliest Atlantic hurricane season in recorded history with over 25,000 deaths. Three different hurricanes, all in October, caused at least 1,000 deaths each; this event has never been repeated and only in the 1893 and 2005 seasons were there two such hurricanes. The season also held the deadliest Atlantic hurricane of all time.
*On June 13, a hurricane "caused deaths and losses" on Puerto Rico.
*New Orleans experienced a powerful hurricane on August 24, causing wind gusting over 160 mph completely destroying 39 of the 43 buldings in Grand Isle, Louisiana then the eye passing over New Orleans that night, severly damaging structures in what is known as the French Quarter, causing harvest-ruining crop damage, severe flooding, and tornadoes. This was from an entry from Count de Lafreinire's diary.
A hurricane hit Jamaica on October 5. It continued its direction, and hit Cuba. The storm caused an estimated 1115 deaths.[1]
The Great Hurricane of 1780 existed in early to mid-October, causing a record 22,000 deaths in the eastern Caribbean Sea.
A powerful hurricane in the Eastern Gulf of Mexico from October 17 to the 21st killed 2,000 people.
