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 Irma
Upon reaching peak intensity, Irma also became the strongest hurricane ever recorded in the Atlantic Ocean outside the Caribbean Sea and Gulf of Mexico, as well as the strongest Atlantic hurricane since Wilma in terms of maximum sustained winds, and the most intense in terms of pressure since Dean in 2007. In addition, Irma achieved one of the longest durations of Category 5 strength winds, and the third-highest accumulated cyclone energy (ACE) index for a tropical cyclone in the Atlantic basin, with a value of 64.9 units. Only the 1899 San Ciriaco hurricane and Hurricane Ivan in 2004 achieved higher values.
