Hurricane William was a destructive, deadly, and costly, Category 3 Major Hurricane that caused mass destruction in Cuba in October and early-November 2018.
On October 21, a disturbance intensified into Tropical Depression Twenty-Five near Cape Verde. Then on the 23rd, Twenty-Five intensified into Tropical Storm William at 4:00 AM UTC.
William then underwent a rapid period of intensification, becoming a Category 3 major hurricane with 115 mph winds.
The countries of Jamaica and Antigua and Barbuda were hit at Category 3 strength on the 27th, causing $9.6 billion in damages and killing 54.
On November 1, William weakened into a remnant low and some remnants of the storm would shift out into the Atlantic and help form Hurricane Xenia.
William completely dissipated on November 4th after killing 54 and causing $9.6 billion in damages. Due to high economic losses, William was replaced with Wade for the 2024 season.
