A major nor’easter is forming right off the US East Coast, triggering flood alerts for millions as hurricane trackers prepare for several days of dangerous weather. The powerful low-pressure system is already sending tropical storm-force winds towards several states, including the Carolinas, Virginia, Maryland, Delaware and New Jersey. Coastal flooding alerts have gone out along most of the East Coast, from Florida to Massachusetts, as meteorologists with AccuWeather warn that this could be a week-long event that develops into a tropical storm or hurricane. AccuWeather Senior Meteorologist Adam Douty said: ‘The most significant coastal impacts are expected close to the center of the storm, potentially on the Outer Banks of North Carolina, southeastern Virginia and the beach communities of Maryland and Delaware.’ Wind gusts of up to 70mph may be seen from North Carolina to southern New Jersey on Monday and Tuesday, hitting coastal communities including Atlantic City, Ocean City and Virginia Beach. The nor’easter has also triggered an official Storm Warning in the Atlantic, affecting anyone traveling 70 to 300 miles off the US East Coast around the Mid-Atlantic states.

The National Weather Service has issued Coastal Flood Advisories in Florida, North Carolina, Virginia, Delaware and New Jersey through Wednesday, affecting more than three million people along the Atlantic. High Surf Advisories in several locations warn that large breaking waves of roughly seven to 14 feet will be possible, creating dangerous swimming conditions and strong rip currents that pull people out into the ocean. Forecasters warn that the storm’s dangerous impacts throughout the week will be the same regardless of whether NWS declares it a named tropical cyclone or not and urged Americans to prepare for days of flooding – particularly during high tide.

‘Since the storm will be slow moving and linger for several days, there will be multiple high tide cycles when coastal flooding would be the most significant, which may compound the impacts from the storm,’ Douty explained in a statement. A nor’easter is a strong storm that forms along the US East Coast, named for the northeast winds that blow over the Mid-Atlantic and New England when a low-pressure system sits over the ocean. While they are usually thought of as giant snowstorms, nor’easters can happen at any time of the year, with the strongest ones hitting in late fall through winter. A storm hitting at the beginning of autumn is considered very rare. This is the second strong nor’easter to hit the East Coast this fall.

The first came in late September 2026, affecting the Mid-Atlantic and Northeast with coastal flooding, high winds and heavy rain. During the current nor’easter approaching the coast, the strongest storm-force winds and highest seas are expected from Monday through Wednesday. Multiple areas in Virginia are expected to be in the heart of the danger zone this week, including Virginia Beach, Norfolk, Chesapeake, Newport News, Hampton, Suffolk and Portsmouth. NWS officials warned in a statement: ‘Expect up to one foot of water above ground level in low lying, vulnerable areas. Some roads and low-lying property including parking lots, parks and lawns near the waterfront will experience shallow flooding.’ This is a breaking story.
