ATLANTA (Reuters) - A winter storm that caused at least four deaths in the U.S. South brought record low temperatures on Wednesday to parts of the region, where it coated roads with ice, snapped power lines and prompted schools to close.
Frigid temperatures and snow were also forecast for the mid-Atlantic region and much of New England through Thursday. The National Weather Service issued winter weather advisories and storm warnings for northern Georgia into Virginia and from Massachusetts to Maine.
In Austin, Texas, a vehicle plunged more than 30 feet (9 meters) off a frozen overpass late on Tuesday, killing a man in his 40s, Austin-Travis County Emergency Medical Service said on its Twitter feed. An 82-year-old woman who suffered from dementia was found dead on Wednesday behind her Houston-area home, likely the victim of exposure to the cold, the Harris County Sheriff's Office said.
In Georgia, two people were fatally struck by a car that slid on an ice patch near Macon, local media said.
At Atlanta's Hartsfield-Jackson International Airport, the nation's busiest with a typical volume of 2,700 arrivals and departures a day, about 470 flights were canceled as of Wednesday afternoon, according to tracking service Flightaware.com.
The sheriff's office in Oconee County, Georgia, east of Atlanta, tried humor to keep people off icy roads.
"I know you need cigarettes, beer and wine to get you through having your kids at home. Can you just do without for a day? Stay home," the office said on its Facebook (NASDAQ:FB) page.
Wednesday's storm is not the first this winter to bring a blast of frosty weather to the South, where parts of Florida and the Louisiana coast saw their first measurable snowfall in decades.
The governors of Georgia, North Carolina and Louisiana declared states of emergency because of severe winter weather conditions, which caused multiple car accidents during rush hour.
Since Monday, more than 9 inches (23 cm) of snow has fallen in Durham, North Carolina, the National Weather Service said.
North Carolina Governor Roy Cooper warned at a news briefing that cold temperatures Wednesday night would make travel conditions even more hazardous.
"The snow is pretty but don't be fooled," Cooper said.
In Atlanta, many people appeared to be heeding Georgia Governor Nathan Deal’s plea to stay off the roads as only a few cars crept along on typically packed highways.
A few people bundled to go out in temperatures that were well below freezing in a city known for its sweltering summer heat.
“We don’t dare try to get the car out of the garage,” said teacher Kimberly Hodges, 40, who was walking her puppy in the city’s East Atlanta Village neighborhood. “It’s a mess out here.”
The weather in Atlanta is not expected to get above freezing until Thursday afternoon. State government offices and many schools were expected to remain closed until at least then.
In Houston, the nation's fourth most populous city, most freeways were closed on Wednesday morning after icing over, the city's Office of Emergency Management said.
In storm-hit North and South Carolina, more than 32,000 homes and businesses were without power as of Wednesday afternoon, utilities data showed.
