Another major winter storm is expected to slam portions of the central and eastern U.S. this week, with heavy snow and strong winds threatening to induce dangerous travel conditions, knock out power and ground flights, forecasters warned.

Winter weather advisories or winter storm warnings are in place for nine states across the U.S. as of early Tuesday morning, and up to nine inches of snow is forecast by the National Weather Service (NWS) in some parts of the country.

Bands of lake effect snow pounding the Tug Hill plateau today are expected to drift south late this afternoon, bringing 3 to 7 inches of snow to much of Central New York through Thursday. More than 3 feet of snow could fall in the traditional lake effect bull’s eye of Tug Hill.
