Hurricane Dorian was the most intense tropical cyclone on record to strike the Bahamas, and is regarded as the worst natural disaster in the country's history. It was also one of the most powerful hurricanes recorded in the Atlantic Ocean in terms of 1-minute sustained winds, with these winds peaking at 185 mph (295 km/h). In addition, Dorian surpassed Hurricane Irma in 2017 to become the most powerful hurricane on record in the open Atlantic region, outside of the Caribbean Sea and Gulf of Mexico. It was the fourth named storm, second hurricane, and the first major hurricane of the 2019 Atlantic hurricane season. Dorian struck the Abaco Islands on September 1 with maximum sustained winds of 185 mph (295 km/h), tying with the 1935 Labor Day hurricane for the highest wind speeds of an Atlantic hurricane ever recorded at landfall. Dorian went on to strike Grand Bahama at similar intensity, stalling just north of the territory with unrelenting winds for at least 24 hours. The resultant damage to these islands was catastrophic; most structures were flattened or swept to sea, and at least 70,000 people were left homeless. After its ravages through the Bahamas, Dorian proceeded along the coasts of the Southeastern United States and Atlantic Canada, leaving behind considerable damage and economic losses in those regions.
