A powerful winter storm blanketed parts of Northeast — and more snow is expected Tuesday

Another two to four inches of snow are possible across the Northeast on Tuesday, while the worst of the snowfall will be in Maine, where much of the state could see more than a foot of snow — and some areas might see up to two feet.

But it’s not just the heavy snow and blizzard-like conditions worrying officials: There are coastal flood alerts — including watches, warnings and advisories — from Maine to the southern shores of Delaware, covering more than 22 million Americans.

Minor to moderate flooding was reported across the region’s coast early Tuesday, enough to flood out basements, roads and cause minor structural damage, according to CNN meteorologist Michael Guy. Water levels are currently about two to four feet above normal, Guy said.

“This type of flooding is extremely dangerous and can be deadly,” Guy added.

Some vaccination sites remain closed Tuesday

Meanwhile, vaccination sites across New York were closed Monday due to the storm and at least five state-run vaccine sites in the state will be closed Tuesday, the governor said.

“Heavy snow, coastal flooding, and high winds are expected to continue across the state today into tomorrow,” Murphy said Monday. “I urge all of our residents to follow weather-related guidance and stay off the roads in order to allow access for essential workers and emergency personnel.”

Dangerous travel conditions across the region

As the storm pummeled Connecticut on Monday, Stamford authorities announced they rescued two people from a pick-up truck that was hit by high winds, snow and a strong tide that caused the vehicle to fill with water.

Firefighters swam to the vehicle and were able to get the female out with the help of an aerial ladder, while they worked to rescue the male as the truck quickly became entirely submerged by water,” the department said in its news release.

“One firefighter maintained a physical hold on the man’s arm and was able to pull him through the small window after the truck was completely under water,” the department said. “Once he was free, firefighters placed the man into the tower ladder and both occupants were brought to shore.”

The male was later transported to the hospital, authorities said.

“Motorist aids can be anything from flat tires, mechanical breakdowns, spin outs, etc,” state police said. “We urge residents to remain off of the roads.”
