A powerful nor'easter is poised to move into northern New England.

A winter storm warning has been posted for much of Maine, New Hampshire and Vermont. National Weather Service meteorologist Andy Pohl says accumulations of a foot or more are expected inland but that a changeover to rain will reduce snowfall totals near the coast.

The storm will pack a wallop. Pohl says the barometric pressure associated with the storm is projected to be the lowest since the Valentine's Day storm in 2014.

Pete Rogers of Maine Emergency Management Agency said it's important for residents to be prepared for heavy snow and strong winds.

The storm is expected to arrive in the Connecticut Valley late Thursday morning and in western Maine by Thursday afternoon. It wraps up Friday.
