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.
1846 Havana hurricane
The 1846 Havana hurricane (also known as the Great Havana hurricane of 1846, San Francisco de Borja hurricane and The Great Gale of 1846) was the most intense tropical cyclone in recorded history for 78 years and the first known Category 5-strength hurricane to strike Cuba. The first indications of the formation of a disturbance were first noted on 5 October in the Caribbean Sea, but little else was known until the storm approached Cuba on 10 October. There, it brought extreme winds and the lowest known atmospheric pressure of the time – 938 mbar (27.70 inHg) – a record which remained unbroken until the development of a later cyclone in 1924. It soon curved toward Florida, where it maintained its intensity, continuing to rapidly hasten northward along the East Coast of the United States to New England. It entered an extratropical transition while situated over New York on 13 October, producing intense Category 2-force winds and unusually little precipitation. Eventually, the gale dissipated over the Canadian Maritimes the following day as a markedly weaker storm.
