The Okeechobee hurricane, also known as the San Felipe Segundo hurricane, was one of the deadliest hurricanes in the recorded history of the North Atlantic basin. The fourth tropical cyclone, third hurricane, and only major hurricane of the 1928 season, this system developed just offshore the west coast of Africa on September 6. Initially a tropical depression, it strengthened into a tropical storm later that day, shortly before passing south of the Cape Verde Islands. Further intensification was slow and halted by late on September 7. About 48 hours later, the storm resumed strengthening and became a Category 1 hurricane on the modern-day Saffir–Simpson hurricane wind scale. Still moving westward, the system reached Category 4 intensity before striking Guadeloupe on September 12. There, the storm brought "great destruction" and 1,200 deaths. The islands of Martinique, Montserrat, and Nevis also reported damage and fatalities, but not nearly as severe as in Guadeloupe.
