Parts of the Northeast were bracing for a powerful winter storm that could dump heavy, wet snow and unleash strong winds, knocking out power to hundreds of thousands of people.

The National Weather Service says the storm is expected to begin late Monday and last into Wednesday. The storm could hit parts of New England, upstate New York, northeastern Pennsylvania, and northern New Jersey, with snowfall totals expected to range from a few inches to a few feet, depending on the area.

“This could be deadly,” New York Gov. Kathy Hochul warned at a storm briefing in Albany. “Let me repeat: This will be a dangerous storm. Please stay off the roads for your own safety.”

Higher elevations in New York’s mid-Hudson region and the Albany area could receive 3 feet (91 centimeter) of snow.

Hochul, who will issue a state of emergency starting at 8 p.m. Monday, said snow plow crews from Long Island and utility crews as far away as Canada were being sent to the region. She also said 100 National Guard members were brought in to assist with emergency response.

Snow in the western part of Massachusetts could exceed 18 inches (45 centimeters), but along the coast, the totals could be 3 or 4 inches (7.5 centimeters to 10 centimeters), Bill Simpson, a spokesman for the National Weather Service in Norton, Massachusetts, said.

“I’m not quite sure of the exact track,” Simpson said. “That makes all the difference in the world.”

A winter storm warning was due to take effect Monday evening and last through Wednesday morning for parts of upstate New York, northeastern Pennsylvania, northern New Jersey, southern sections of Maine, New Hampshire and Vermont as well western Massachusetts and parts of Connecticut and Rhode Island.

Some schools in the region canceled classes for Tuesday ahead of the storm, and Maine Gov. Janet Mills directed that all state offices be closed on Tuesday.

Connecticut’s largest electricity provider, Eversource, was bringing in extra crews from other states as it prepared for up to 130,000 power outages.

“That combination of heavy wet snow, long duration of sustained winds, long duration of gusts will almost certainly bring down tree limbs and entire trees,” said Steve Sullivan, president of Connecticut electric operations for Eversource. “Those will damage the electric system.”

In New Hampshire, the storm will hit on Election Day for town officeholders. Dozens of communities postponed voting, while others reminded voters that they could vote by absentee ballot on Monday instead.

Similar back-to-back Election Day storms in 2017 and 2018 sparked widespread confusion about who could reschedule elections.

Lawmakers have since changed the law to allow town moderators to postpone elections if the National Weather Service issues a storm warning. For Tuesday, such warnings have been issued for at least parts of seven of the state’s 10 counties.
