Nor’easter expected to bring heavy snow, flooding to Northeast

A winter storm is expected to pummel the Northeast with heavy snow and rain starting Monday night and lasting through Tuesday morning, according to the National Weather Service (NWS).

The storm is slated to cross the mid-South on Monday before transitioning into a “strong nor’easter” for the mid-Atlantic and New England by Tuesday, the Weather Service said, with some areas expected to see snowfall totals of 6 to 12 inches.

Heavy snowfall on Monday is likely in the area stretching from central Oklahoma through southern Missouri, including in the Ozarks, forecasters predicted, before moving toward the mid-Atlantic states in the evening, with cold air producing large amounts of snow.

Heavy snowfall accumulation is expected across central and eastern Pennsylvania, up through northern New Jersey and New York, where people could see at least 6 inches of snow, the NWS of New York said. Areas of the lower Hudson Valley and Connecticut could see closer to a foot of snow, NWS New York added.

Other parts of Connecticut, Rhode Island and Massachusetts are expected to be pounded by the nor’easter as well, with snow expected to fall at a rate of 1 inch to 2 inches per hour between 9 a.m. and 3 p.m. Tuesday. Snowfall totals could reach more than 8 inches of snow, the NWS forecasted.

NWS Boston warned travel will be “very difficult” Tuesday, and winter storm warnings are in effect for southern New England and parts of northwestern Massachusetts. Winter storm watches are in effect across southeastern Massachusetts.

Forecasters also warned of moderate coastal flooding in Long Island’s South Shore, with a coastal flood advisory starting at 8 a.m. Monday and lasting through 10 a.m. Tuesday. Vulnerable areas including roads, parking lots, parks, lawns and homes could be at risk, and road closures are possible, the Weather Service said.

Airlines are already taking precautions ahead of Tuesday. Southwest Airlines, Delta, American Airlines, Jet Blue and Spirit have issued advisories for multiple airports stretching from Pennsylvania through New Hampshire.
