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.
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.
