A deadly winter storm that has coated much of the southeastern United States with ice is moving up the east coast, taking aim at the mid-Atlantic and Northeast.
Some cities can expect more than 30 centimeters of snow by the end of the day Thursday. Major school systems have already closed and residents are packing supermarkets to stock up on essentials.
The storm killed at least nine people as it pushed across the usually mild Southeast Wednesday, coating highways from Texas through the Carolinas with ice.
Many drivers in North Carolina, figuring it is safer to walk than drive, ignored authorities and abandoned their cars on the slick highways, causing a huge traffic jam.
Heavy ice has brought down trees and power lines, knocking out electricity to hundreds of thousands. Airlines canceled thousands of flights.
