A powerful nor’easter is poised to strike the East Coast, affecting millions from Massachusetts to Maryland with heavy rain, strong winds, and coastal flooding. The storm, which is expected to hit today and continue through the weekend, has resulted in the cancellation of events and the declaration of a state of emergency in several New Jersey counties. Predictions indicate gusts exceeding 50 mph, particularly along coastal areas, with airlines waiving flight-change fees in anticipation of disruptions. Residents are advised to prepare for significant impacts, including potential power outages, as the storm approaches.
