Around 40 million people in the U.S. are under a winter storm warning from an unusual blast of severe winter weather.

The beaches even may see a wintry mix of snow, sleet and freezing rain, the weather service said, with the mainly snow expected.

Northwestern New Jersey counties have reported the highest snow totals of up to 7 inches from Sunday’s winter storm. Morris County had the top three totals reported to the National Weather Service with Kinnelon topping the list at 7 inches.

A Winter Storm Watch is in effect from Monday night through Tuesday for the area. The wintry mix begins early Tuesday morning with snow across the northern tier, spreading south as temperatures fall below freezing throughout the day.

On Monday at 2:03 p.m. the National Weather Service issued an updated winter storm warning valid from Tuesday 6 a.m. until Wednesday 6 a.m. for Lowndes, Montgomery, Macon, Bullock, Russell, Pike and Barbour counties.
