MEMPHIS, Tenn. - A late fall cold snap that has gripped much of the country is being blamed for a handful of deaths and has forced people to deal with frigid temperatures, power outages by the thousands and treacherous roads.
Weather forecasters say the powerful weather system has Virginia and the Mid-Atlantic in its icy sights next.
Temperatures in Montana and South Dakota were more than 20 degrees below zero during the day Saturday while much of the Midwest was in the teens and single digits. Wind chill readings could drop as low as 50 below zero in northwestern Minnesota, weather officials said.
Icy conditions were expected to last through the weekend from Texas to Ohio to Tennessee, and Virginia officials warned residents of a major ice storm likely to take shape Sunday, resulting in power outages and hazards on the roads.
In California, four people died of hypothermia in the San Francisco Bay area and about a half-dozen traffic-related deaths were blamed on the weather in several states.
Icy, treacherous sections of Interstate 35 north of Dallas were closed for hours at a time over the last day as tractor-trailers had trouble climbing hills, wrecks occurred and vehicles stalled, authorities said.
Tina Pacheco, her husband and two friends were traveling through Texas on their way to Mexico when the ice-laden interstate became so treacherous that traffic came to a standstill. They were forced to spend Friday night in their pickup truck. They parked on a service road and kept the truck running for heat.
"We couldn't go anywhere," she said, adding, "It's a good thing we had gas."
Jody Gonzalez, chief of Denton County Emergency Services, said about 200 people were in shelters in the Sanger area after getting stuck on the highway. People in that area of I-35 were driving through ruts in 4-inch-thick ice, he said.
Texas Department of Transportation spokeswoman Michelle Releford said road graders and more sand and salt trucks were being sent to try to ease the ice problems.
"We're sending in everything we've got," said Releford.
About 75,000 customers in the Dallas area were without power Saturday, down from a peak of more than 270,000. Oklahoma utilities reported more than 7,500 power outages across the state and western Arkansas.
