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.
1848 Tampa Bay hurricane
The 1848 Tampa Bay hurricane, also known as the Great Gale of 1848, was the most severe hurricane to affect Tampa Bay in the U.S. state of Florida and is one of only two major hurricanes to make landfall in the area, the other having occurred in 1921. It affected the Tampa Bay Area September 23–25, 1848, and crossed the peninsula to cause damage on the east coast on or about September 26. It reshaped parts of the coast and destroyed much of what few human works and habitation were then in the Tampa Bay Area. Although available records of its wind speed are unavailable, its barometric pressure and storm surge were consistent with at least a Category 4 hurricane. A survivor called the storm "the granddaddy of all hurricanes."
