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.
List of off-season Atlantic hurricanes
Off-season cyclones are most likely to occur in the central to western Atlantic Ocean, and most do not make landfall. Of the storms that did strike land, most affected areas surrounding the Caribbean Sea. Cumulatively, at least 441 deaths occurred due to the storms, primarily on the islands of Hispaniola and Cuba; a tropical storm in May 1948 struck the Dominican Republic to become the deadliest off-season storm. However, an unofficial hurricane in 1863 killed 110 people, in a shipwreck off Florida and on land. The same storm was estimated to have reached winds of 105 mph (165 km/h), making it the strongest hurricane between December to May; the strongest currently in the official database was a March hurricane in 1908 that reached winds of 100 mph (160 km/h). In addition, the strongest off-season cyclone to make landfall in the United States was Tropical Storm Beryl in 2012, which made landfall near Jacksonville Beach, Florida with 65 mph (100 km/h) winds. The most recent off-season storm is Tropical Storm Alberto in May 2018.
