1900 Galveston hurricane
The Great Galveston Hurricane, known regionally as the Great Storm of 1900, was the deadliest natural disaster in United States history, one of the deadliest hurricanes (or remnants) to affect Canada, and the fourth-deadliest Atlantic hurricane overall. The hurricane left between 6,000 and 12,000 fatalities in the United States; the number most cited in official reports is 8,000. Most of these deaths occurred in the vicinity of Galveston after storm surge inundated the entire island with of water. In addition to the number killed, every house in the city sustained damage, with at least 3,636 destroyed. Approximately 10,000 people in the city were left homeless, out of a total population of nearly 38,000. The disaster ended the Golden Era of Galveston, as the hurricane alarmed potential investors, who turned to Houston instead. The Gulf of Mexico shoreline of Galveston island was subsequently raised by and a seawall erected.
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."
