With rain changing over to snow across the northeast today, and heavy snow continuing from yesterday’s snowfall on the northern side of the system, the National Weather Service continues to expand Winter Storm Warnings for hazardous winter conditions in the eastern United States today.

With the threat of heavy snow shifting a bit more south and east, the National Weather Service (NWS) has included Middlesex County in New Jersey with the Garden State’s existing Winter Storm Warnings. A half foot or more of snow could fall there according to the NWS’s morning update.

The NWS has also issued winter storm warnings for western North Carolina, eastern Tennessee, southwestern Virginia, eastern Kentucky, and the higher elevations of eastern West Virginia. Along the higher peaks of the Appalachian Mountains, heavy snow is likely to fall as the system rotates through the region today.

Winter Storm Watches that were up yesterday were upgraded to Winter Storm Warnings across much of central Maine. Snow is expected to get heavier there later today and continue into the first part of tomorrow.

As the storm takes shape and intensifies off the northeast coast, a threat of coastal flooding will increase too. Because of that threat, there are coastal flood advisory products in effect in and around the New York City metro area now.

In areas where less snow will fall, or in areas of the southern interior Mid Atlantic where freezing rain could be an issue, Winter Weather Advisories are up.
