A dangerous winter storm combining high winds and ice swept through parts of the US Southeast on Sunday, knocking out power, felling trees and fences and coating roads with a treacherous, frigid glaze.

Tens of thousands of customers were without power in Georgia, North Carolina, South Carolina and Florida. Highway patrols were reporting hundreds of vehicle accidents, and a tornado ripped through a trailer park in Florida. More than 1,200 Sunday flights at Charlotte Douglas International were cancelled – more than 90% of the airport’s Sunday schedule, according to the flight tracking service flightaware.com.

Winter Storm Izzy dumped as much as 10 inches of snow in some areas of western North Carolina as the system moved across the southeastern US, said Brian Hurley, a meteorologist with the Weather Prediction Center in College Park, Maryland.

First Sgt. Christopher Knox, a spokesman for the North Carolina Highway Patrol, said that by midafternoon, the agency had responded to 300 car crashes and nearly 800 calls for service. Two people died Sunday when their car drove off the road and into trees in a median east of Raleigh. The driver and passenger, both 41-year-old South Carolina residents, were pronounced dead at the scene of the single-vehicle crash. Knox said investigators believe the car was driving too fast for the conditions, described as mixed winter precipitation.

Meanwhile, Transportation Secretary J. Eric Boyette said many roads in the central and western part of the state were covered with ice. He said the eastern part of the state was being hit with high winds and rain.

More than 260,000 customers were without power by midafternoon Sunday, according to poweroutage.us. Especially hard hit was North Carolina, with 90,000 outages. The remaining outages were in Georgia, South Carolina and Florida.

The National Weather Service confirmed that a tornado with 118 mph winds (190 kph) struck southwest Florida. The weather service said the tornado was on the ground for almost two miles (3 kilometers) with a maximum path width of 125 yards (115 meters). Thirty mobile homes were destroyed and 51 had major damage. Three minor injuries were reported.

Edward Murray, 81, told the Naples Daily News in southwest Florida that he was inside his mobile home Sunday morning when a tornado picked it up and tossed it on top of his neighbor’s home.

“That’s my house that’s turned upside down,”he told the newspaper. “The tornado took me off my feet, blew me toward the east wall and buried me under the sink, refrigerator, kitchen chairs and everything else.”

Murray and his daughter, Cokie, escaped unharmed, crawling from the wreckage.

“I was so happy when I saw the sky,”Murray told the newspaper. “I said to the devil, `It’s not going to be today’.”

Virginia State Police said traffic came to a standstill Sunday afternoon on Interstate 81 in Roanoke County after a tractor-trailer jackknifed and the cab of the truck disconnected from the trailer in the northbound lanes. Two additional accidents occurred in the traffic backup, one with minor injuries. The Virginia Department of Transportation said a detour was being set up. “Please stay off the roads if possible. Begging again! Hazardous conditions,”read a tweet from VDOT’s Salem office.

From midnight to 12:45 p.m., Virginia state troopers responded to 142 traffic crashes and 162 disabled vehicles. No traffic fatalities were reported.

The West Virginia Department of Homeland Security tweeted photos of snow-covered roads in the southern part of the state and advised residents to “keep calm and hunker down.” The agency says the storm is moving north and most areas of the state are expected to have accumulations of at least 4 inches (10 centimeters), with up to 12 inches (30 centimeters) possible in the mountains.

In Tennessee, there were multiple reports of abandoned and wrecked cars on snow-covered roads.

The storm system could cause hazardous driving conditions over a large portion of the eastern US through Monday as the wet roadways refreeze in southern states and the storm turns and moves northward through the Mid-Atlantic states and New England.

While not a record-breaking storm in terms of snowfall, the large system could impact a dozen or more states.

“It’s a very expansive storm,” Hurley said. “A lot of real estate is going to get four to eight inches of snow and a lot more are also going to get to get some of that ice accumulation.”

New York City was expected to be spared from most, if not all, of the snowfall, but Long Island and Connecticut coastal areas were expecting gale conditions. Upstate New York was projected to get hit with up to a foot of snow to go along with high winds.

Six to 13 inches (15 to 33 centimeters) of snow was expected in parts of east-central Ohio and western Pennsylvania from Sunday afternoon.

Frigid temperatures lingered across New England on Sunday, with wind chills in northern Vermont reported at -27 Fahrenheit (-33 Celsius). In Boston, where a cold emergency was declared on Saturday, wind chills remained below zero (-17 C) even as the region started the thaw.
