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.
1928 Okeechobee hurricane
The Okeechobee hurricane of 1928, also known as the San Felipe Segundo hurricane, was one of the deadliest hurricanes in the recorded history of the North Atlantic basin; it was the fourth tropical cyclone, third hurricane, and only major hurricane of that year's season. It developed off the west coast of Africa on September 6 as a tropical depression, but it strengthened into a tropical storm later that day, shortly before passing south of the Cape Verde islands. Further intensification was slow and halted late on September 7. About 48 hours later, the storm strengthened and became a Category 1 hurricane on the Saffir–Simpson hurricane wind scale. Still moving westward, the system reached Category 4 intensity before striking Guadeloupe on September 12, where it brought great destruction and resulted in 1,200 deaths. The islands of Martinique, Montserrat, and Nevis also reported damage and fatalities, but not nearly so severe as in Guadeloupe.
