1900 Galveston hurricane
The Great Galveston hurricane made landfall on September 9, 1900, near Galveston, Texas. It had estimated winds of at landfall, making the cyclone a Category 4 storm on the modern day Saffir–Simpson Hurricane Scale.
The hurricane caused great loss of life, with a death toll of between 6,000 and 12,000 people; the number most cited in official reports is 8,000, giving the storm the third-highest number of deaths or injuries of all Atlantic hurricanes, after the Great Hurricane of 1780 and Hurricane Mitch in 1998. The Galveston Hurricane of 1900 is the deadliest natural disaster to strike the United States. This loss of life can be attributed to the fact that officials for the Weather Bureau in Galveston brushed off the reports because the city had "weathered them all" and they did not realize the threat. The second-deadliest storm to strike the United States, the San Ciriaco hurricane of 1899, caused around 3,400 deaths.
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.
