Live updates: What to know about the nor’easter hitting Massachusetts

Weather

Meteorologists are predicting up to 2 feet of snow and high winds, which could affect trees and power lines.

With high winds, power outages, and up to two feet of snow expected Monday, state officials are warning residents about the impacts of the nor’easter affecting much of the Northeast.

“This is one to take seriously,” Governor Maura Healey told reporters Sunday afternoon. “Our ask and plea, as always, is going to be to please stay off the roads for the safety of the folks who are out there trying to clear the roads, keep power on, and keep people safe.”

Meteorologists are predicting between 18 to 24 inches of snow, with the heaviest snowfall coming between 4 a.m. and noon Monday. But, the heavy, wet snow and high winds could affect trees and power lines, leading to outages. Southeast Massachusetts will likely see some of the more significant impacts, state officials said.

Here’s what to know about the storm.

The MBTA’s subways, buses, and trains will all operate under an emergency schedule during the storm, officials announced.

The MBTA’s trains and buses will be operating at reduced levels Monday, similar to a Sunday schedule, the transit agency announced. While officials are asking people to stay home Monday, any commuters should expect longer wait times.

The Mattapan Line will be suspended and replaced with shuttle buses on Monday, and all ferry routes will also be suspended due to wind. 

“We are certainly prepared to go into this storm and give it 110 percent to keep our lines open,” COO Ryan Coholan said. “We don’t have any staffing concerns right now. We have all hands on deck to attack this incoming weather event.”

Schedules may be adjusted on Tuesday as well, Coholan said, depending on the storm’s clean-up. Icy conditions are expected on Tuesday morning for drivers.

Commuter Rail lines will be running on reduced storm schedules, the MBTA said, and many bus lines will be detoured on their snow routes. Check the MBTA’s online schedules for specific lines.

“Unless your travel is absolutely necessary,” Coholan said, “I urge folks to stay home, stay off the roads and let all of us get out there so we can get things open back up and resume normal service.”

Doordash, an app-based food delivery service, said it would pause operations in Boston due to the incoming storm.

DoorDash operations will be temporarily suspended between 9 p.m. Sunday through at least noon Monday “across Boston,” a spokesperson said, depending on conditions.

“A historic blizzard is bearing down on the Northeast,” spokesperson Julian Crowley said. “We’re suspending operations across impacted areas to keep our community safe. This is a serious storm — we’ll resume when it passes.”

Grubhub, another delivery service, is also pausing deliveries until 11 a.m., a spokesperson said. Uber Eats did not respond to inquiries from Boston.com Sunday night.

DoorDash has already shut down in New York City.

Boston declares snow emergency

All Boston schools and city buildings will be closed Monday after Mayor Michelle Wu declared a snow emergency ahead of the blizzard expected to drop to two feet of snow on the city.

The snow emergency went into effect at 2 p.m. Sunday, which also marked the start of the city’s parking ban. Vehicles parked on major roads and main arteries will be towed, the city said.

​”Preparations for snow are already underway across every neighborhood, and our City teams will be out around the clock through the nor’easter and the cleanup afterwards,” Wu said in a statement. “We ask everyone to plan ahead, stay safe and warm, and stay off the roads to help our public works and public safety efforts.”

All library branches will be closed, as well as Boston Centers for Youth & Families. Curbside trash and recycling collection is delayed one day, the city said.

Residents in most Boston neighborhoods have two days after the end of a snow emergency to use a space saver. However, space savers are banned in the South End and Bay Village.

Wet snow, wind likely to affect power

Massachusetts is expected to face significant power outages, said Rebecca Tepper, the secretary of the Executive Office of Energy and Environmental Affairs.

“We are expecting windy conditions and wet snow, and there is already snow on the trees. These conditions increase the likelihood of power outages due to the risk of falling trees,” Tepper said. 

The utilities teams have prestaged line and tree crews on Cape Cod, Martha’s Vineyard, Nantucket, and other areas expected to be most affected by wind and, but it may take multiple days to restore power.

Tepper also warned residents to stay away from downed wires or trees with wires on it.

“You have to assume it’s live. Do not touch it. Call 911 immediately,” Tepper said.
