Part of the 1944 Atlantic hurricane season

The 1944 Great Atlantic hurricane was a destructive and powerful tropical cyclone that swept across a large portion of the United States East Coast in September 1944. New England was most affected, though so were the Outer Banks, Mid-Atlantic states, and the Canadian Maritimes. The storm's ferocity and path drew comparisons to the 1938 Long Island Express, one of the worst storms in New England history.

Its precursor was first identified well east of the Lesser Antilles on September 4, but the disturbance only became well organized enough to be considered a tropical cyclone on September 9 northeast of the Virgin Islands. Tracking west-northwest, the storm gradually intensified, curved northward, and reached peak intensity as a Category 5 hurricane on September 13 north of the Bahamas. A day later, the storm passed the Outer Banks and later made landfall on Long Island and Rhode Island as a weaker hurricane on September 15. The storm eventually became an extratropical cyclone, moving northeast, and merged with another extratropical system off Greenland on September 16.
