Strong winds Monday could lead to coastal flooding from Virginia to Maine, Guy said. Buffalo could see wind gusts up to 45 mph, while New York City may get 55-mph gusts, and some parts of Maine could get gusts up to 65 mph.
Cold air behind the storm system and a prior arctic plunge over the Northeast will keep temperatures below freezing until Wednesday in that region, while parts of the South and Mid-Atlantic will see temperatures recover by Tuesday, Guy said. But another round of bitter cold, possibly with snow, is shaping up for the end of this week, he added.
Drivers warned to stay home due to slick roadways
While the worst impacts of the storm shift Northeast, roads will remain dangerous Monday across much of the Southeast, especially on overpasses and at higher elevations, Guy said.
Temperatures at or near freezing will keep roads slick in Knoxville, Tennessee, and Asheville, North Carolina, and areas to the north through central Ohio. There could also be icing issues Monday in places including Winston-Salem, North Carolina; Roanoke, Virginia; and Charleston, West Virginia, Guy said.
The governors of South Carolina, North Carolina and Virginia activated members of the National Guard to help with storm response.
“They’re equipped with emergency response vehicles that can move through the snow,” North Carolina Gov. Roy Cooper said Sunday of the 200 Guard members deployed in his state. “As much as 8 to 12 inches of snow has fallen in some counties, and significant icing is causing trouble in the central part of the state.”
North Carolina authorities responded to more than 400 crashes Sunday, State Highway Patrol spokesperson First Sgt. Christopher Knox told CNN Sunday night. Two people, both 41 and from Myrtle Beach, South Carolina, were killed Sunday morning on Interstate 95 in Nash County after their vehicle left the road and struck trees in the median, he said.
“Exceeding a safe speed for the conditions is the proximate cause of the collision,” Knox said. “Weather at the time was a mixture of wintry precipitation.”
And in Virginia, 75 service members were staged for storm response, including “personnel with chain saws for clearing fallen trees and heavy duty tactical vehicles capable of traveling through deep snow at key locations,” the Virginia National Guard said in a news release.
Accidents also were reported Sunday across north Georgia, the National Weather Service office in Atlanta reported, and Gov. Brian Kemp asked residents to stay off the roads.
Storm spawned tornadoes in Florida
But the system brought much more dangerous conditions to southwest Florida, where at least two tornadoes destroyed at least 28 homes in Lee County and damaged others, officials said.
At least 62 homes are currently “unlivable,” said Cecil Pendergrass, cochairman of the county’s board of commissioners, at a news conference.
One twister was an EF2 tornado with maximum winds of 118 mph. It may have completely destroyed 30 mobile homes of the 108 mobile homes damaged near Fort Myers, according to a damage survey by the National Weather Service.
Four injuries were reported, but no one was taken to a hospital, officials said.
In Charlotte County, north of Fort Myers, an EF1 tornado with winds of 110 mph left behind a path of destruction, according to the weather service.
“A waterspout moved across Gasparilla sound near Boca Grande Causeway before then moved ashore as a short-lived tornado near Placida damaging at least 35 homes and a marina storage facility,” the weather service said in a bulletin.
Correction: An earlier version of this story gave the wrong state for a city that could face icing issues. It is Charleston, West Virginia.
