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.
Hurricane Allen
As a result of Allen's impact's the name Allen was retired from the Atlantic naming list by the World Meteorological Organization and will not be used for a future Atlantic hurricane. It was replaced with the name Andrew when the list of names was reused during the 1986 Atlantic hurricane season.
When Allen reached Category 5 intensity on August 5, it became the earliest Category 5 storm ever recorded. This record stood until Hurricane Emily surpassed it on July 16, 2005. Allen is one of three Atlantic hurricanes to reach Category 5 on the Saffir-Simpson hurricane scale on three separate occasions, the others being Hurricane Ivan and Hurricane Isabel. Allen also produced the fifth-lowest minimum pressure ever recorded in the Atlantic basin at 899 mbar (hPa) and was the strongest known hurricane in the basin, in terms of pressure, since 1935. Until then, it was the second strongest hurricane by pressure in the Atlantic Basin, but was since pushed down to fifth, and no hurricane has achieved winds in this basin since then. It remains the most intense storm ever in August. Allen spent nearly 3 days as a Category 5 storm, initially the longest stretch of any previous Atlantic hurricane on record. However, a reanalysis of the 1932 Cuba hurricane showed that it spent 3 hours longer at Category 5 intensity than Allen, and Hurricane Irma in 2017 also spent slightly more time as a Category 5 hurricane than Allen. Five typhoons have spent longer as Category 5 storms, including most recently Karen and Nancy in the early 1960s.
