As of 11:30 a.m. EST Friday, this reports story is no longer being updated. For the latest on the nor'easter, click here.

Damaging winds, coastal flooding and heavy snow will impact the northeastern United States through Friday due to a potent bomb cyclone.

Strong winds will howl across the region and may contribute to power outages from North Carolina to Maine. The strongest winds will likely be along the coast of eastern Massachusetts, where they will reach hurricane-force strength.

The strong onshore winds will lead to substantial coastal flooding and beach erosion in coastal areas.

Winds will not be as strong farther inland but can still contribute to power outages.

The heaviest snow is forecast over much of western New York and northern Pennsylvania, but several inches are possible in and around New York City.
