1900 Galveston hurricane
The Great Galveston hurricane made landfall on September 9, 1900, near Galveston, Texas. It had estimated winds of at landfall, making the cyclone a Category 4 storm on the modern day Saffir–Simpson Hurricane Scale.
The hurricane caused great loss of life, with a death toll of between 6,000 and 12,000 people; the number most cited in official reports is 8,000, giving the storm the third-highest number of deaths or injuries of all Atlantic hurricanes, after the Great Hurricane of 1780 and Hurricane Mitch in 1998. The Galveston Hurricane of 1900 is the deadliest natural disaster to strike the United States. This loss of life can be attributed to the fact that officials for the Weather Bureau in Galveston brushed off the reports because the city had "weathered them all" and they did not realize the threat. The second-deadliest storm to strike the United States, the San Ciriaco hurricane of 1899, caused around 3,400 deaths.
1866 Atlantic hurricane season
Great Nassau Hurricane of 1866 or The Great Bahamas Hurricane of 1866 was the sixth hurricane of the season and was also the longest-lasting. The brig "Jarien" encountered the hurricane on September 24 to the west-southwest of the Cape Verde islands. The track is unknown for the following five days, until another ship reported a hurricane about 20 miles (32 km) north of Anegada in the British Virgin Islands. The hurricane affected the Leeward Islands, washing several ships ashore and destroying a pier in St. Thomas. On September 30 through the following day, the cyclone moved through the Turks and Caicos Islands, becoming what was considered "one of the most terrific hurricanes ever known". About 75% of the population was left homeless and moneyless.
