Rare September Nor’easter to Impact U.S. Northeast
US · Published Sep 23, 2026
A rare September nor’easter is forecast to develop off the East Coast later this week, potentially bringing coastal flooding, gusty winds, and rain to parts of the Mid-Atlantic and Northeast.
Nor’easters, which typically occur from mid-fall to mid-spring, are strong coastal storms characterized by northeast winds.

Impact & Risks

The storm poses significant risks of coastal flooding, particularly from Virginia to New England, with some areas potentially reaching major flood stages by Thursday. Gusty winds, possibly up to 50 mph, could cause damage and rough seas, especially if the storm tracks closer to the coast. Rainfall may exacerbate flooding in areas already saturated from recent storms, such as New Jersey and Connecticut. Coastal regions, including Boston and Portland, Maine, could experience prolonged impacts if the storm lingers into next week. The combination of high tides and strong winds increases the likelihood of serious flooding in vulnerable areas.
