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.
Air National Guard
On 29 August 2005, the largest natural disaster the Air National Guard faced in its then 58-year history began when Hurricane Katrina hit the United States Gulf Coast. The most severe damage came from a 30-plus-foot storm surge along the Mississippi coast and the north shore of Lake Pontchartrain in Louisiana and breaks in the levies along a canal in New Orleans. Several weeks later Hurricane Rita devastated portions of western Louisiana and eastern Texas, and then the less severe Hurricane Wilma damaged Florida.
