On August 30, Dorian became a first major hurricane of the season, and then became a Category 4 hurricane from a Category 2 in 9 hours. Dorian later became a Category 5 hurricane, making 2019 the fourth consecutive season to feature at least one Category 5 hurricane (Matthew in 2016, Irma and Maria in 2017, and Michael in 2018). The storm was the second most-intense storm to strike anywhere in the Atlantic basin.
