Blizzard live updates: Snow totals top 2 feet as wind gusts reach 80 mph

The governors of seven Northeast states have declared states of emergency as a severe winter storm was moving up the East Coast.

States of emergency have been declared in Connecticut, Delaware, Massachusetts, New Jersey, New York, Pennsylvania and Rhode Island.

Maryland Gov. Wes Moore has declared a “state of preparedness” as the storm intensified Sunday afternoon.

The governors are advising people to stay off the roadways and highways during the storm, and several states -- including New York, Connecticut and Rhode Island -- have issued travel bans.

DoorDash has activated its severe weather protocol and will temporarily suspend operations across New York City on Sunday night, the food delivery company said.

DoorDash said it plans to begin suspending operations at 8:30 p.m. ET on Sunday, but said it could shut down sooner depending on weather conditions. Operations will remain suspended until at least noon on Monday, the company said.

The company said it plans to shut down at least 30 minutes ahead of a 9 p.m. citywide travel ban goes into effect. New York City Mayor Zohran Mamdani announced the ban earlier Sunday for all vehicles, save for "essential and emergency trips."

"New York City is bracing itself ahead of a historic blizzard – the first in nearly a decade – with a foot of snow or more and dangerous wind gusts expected," DoorDash spokesperson Julian Crowley said in the statement. "We're suspending operations early to keep Dashers safe and off the streets before the travel ban takes effect. We're closely monitoring conditions and will resume as soon as it's safe to do so."

New York Gov. Kathy Hochul cautioned residents of her state on Sunday afternoon, saying they are experiencing the "calm before the storm."

"The worst is yet to come," Hochul said at a news conference. "Lives are at stake."

Hochul said New York City could be in store for one of the "top 10 worst winter storms in the last 150 years."

The Hudson Valley, New York City and Long Island are expected to receive wet snow, which has the ability to take down power lines, the governor said.

"Long Island and New York City and lower Hudson Valley are literally in the direct eye of the storm," Hochul said.

Hochul warned that subway service in New York City could see "some disruptions" due to the storm. Subways are expected to continue running throughout the storm, but mostly on local tracks.

Metro North train service will run on a weekend schedule and Long Island Rail Road commuter train service is expected to be suspended at 1 a.m. on Monday.

"There is no way these predictions are wrong," Hochul said. "It is coming, and it's going to be hard felt."

The Long Island Rail Road announced it will suspend service systemwide beginning at 1 a.m. Monday due to the expected blizzard conditions.

"The Long Island Rail Road is the busiest commuter railroad in North America, carrying approximately 250,000 customers each weekday on 947 daily trains," according to New York's Metro Transit Authority.

New Jersey Transit similarly announced that it will suspend its bus and light rail commuter service beginning at 6 p.m. Sunday.

New York City Mayor Zohran Mamdani announced earlier Sunday that roads in the city, including highways and bridges, would be "closed to all vehicles," including cars, trucks, scooters and e-bikes, beginning at 9 p.m. through noon on Monday in anticipation of the blizzard, except for "essential and emergency trips."

Mamdani also declared a local state of emergency due to the blizzard, including cancelling school Monday.
