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.
1927 Nova Scotia hurricane
The 1927 Nova Scotia hurricane (also known as the 1927 Great August Gale or the Great Gale of August 24) was the deadliest Canadian hurricane since at least 1900. The first observed storm of the season, this cyclone developed from a tropical wave over the deep tropics of the Atlantic Ocean on August 18. Initially a tropical storm, it moved west-northwestward and intensified into a Category 1 hurricane on the modern day Saffir–Simpson hurricane wind scale by August 19. The storm deepened significantly over the next few days, and by August 22, it peaked as a Category 3 hurricane with maximum sustained winds of 125 mph (205 km/h). Around that time, the system began curving northwestward and later northward. By August 23, it turned to the north-northeast and then began weakening on August 24. Thereafter, the storm accelerated toward Atlantic Canada. Late on August 24, the hurricane struck near Yarmouth, Nova Scotia, as a Category 2 hurricane, just before becoming extratropical.
