A significant Nor'easter is predicted to impact the Mid-Atlantic and Northeast regions, starting this Sunday. The National Weather Service (NWS) Weather Prediction Center (WPC) forecasts heavy snowfall and strong winds, leading to localized blizzard conditions and substantial impacts, especially in coastal areas. Snowfall rates could surpass one inch per hour, with total accumulations ranging from one to two feet. The combination of heavy snow and wind gusts between 40 and 70 mph is expected to cause widespread power outages. Residents should brace for potential disruptions, including travel delays and possible school closures.
