East Coast and West Coast face severe storms and flooding risks

nor'easter coastal flooding flash flood risk weather alerts extreme weather

A powerful nor’easter is impacting the U.S. East Coast, bringing high winds, heavy surf, and coastal flooding from North Carolina to New Jersey. In North Carolina, mandatory evacuations have been issued for Hatteras Island due to ocean overwash. The storm is causing tidal flooding in Virginia, Maryland, Delaware, and New Jersey, with significant concerns for the Jersey Shore and the Delmarva Peninsula. Some areas, including the Tri-State region, have experienced power outages and transportation disruptions, such as partial suspensions of Long Island Rail Road lines.

Simultaneously, a strong storm system is moving through Southern California, bringing heavy rain, potential thunderstorms, and a risk of flash flooding and debris flows. The National Weather Service has issued flood watches for the Santa Monica Mountains and surrounding coastal areas, including Malibu and the Palisades. Forecasters warn of potential localized flooding in urban areas and vulnerable burn scars.

In the West, heavy rain and flash flood risks extend from Southern California through the Rockies and into the Southwest, with millions of people in Arizona under flood watches. Mountain snow is also expected in some western regions.
