Business owners place sandbags and seal doors with tape to keep out floodwaters during a major nor'easter in Atlantic City, New Jersey, on September 26, 2026. More than 40 million people in the northeastern United States braced September 25 for heavy rain and strong winds as an unusually powerful storm for the season was forecast to crash into the region. New York, Boston and Philadelphia were all in the firing line of the "Nor'easter" -- so labeled for its northeasterly winds -- as authorities warned of potential flooding, downed trees and damaged power lines.
