1900 Galveston hurricane

The 1900 Galveston hurricane (otherwise known as the Great Galveston hurricane and the Galveston Flood and known regionally as the Great Storm of 1900 or the 1900 Storm) was a catastrophic tropical cyclone that became the deadliest natural disaster in the history of the United States. The strongest storm of the 1900 Atlantic hurricane season, it left between 6,000 and 12,000 fatalities; the number most cited in official reports is 8,000. Most of these deaths occurred in and near Galveston, Texas, after the storm surge inundated the coastline city with 8 to 12 ft (2.4 to 3.7 m) of water. As of 2026, it remains the fourth deadliest Atlantic hurricane on record. In addition to the number killed, the storm destroyed about 7,000 buildings in Galveston, which included 3,636 demolished homes; every dwelling in the city suffered some degree of damage. The hurricane left approximately 10,000 people in the city homeless, out of a total population of fewer than 38,000. The disaster ended the Golden Era of Galveston; the hurricane alarmed potential investors, who turned to Houston instead. In response to the storm, three engineers designed and oversaw plans to raise the Gulf of Mexico shoreline of Galveston Island by 17 ft (5.2 m) and erect a 10 mi (16 km) seawall.

On August 27, 1900, a ship east of the Windward Islands detected a tropical cyclone, the first observed that year. The system proceeded to move steadily west-northwestward and entered the northeastern Caribbean on August 30.
