Rare winter deep freeze forces residents of southern U.S. to cope with brutal cold

A rare deep freeze brought snow and ice to normally temperate parts of the southern United States,forcingTexas's electric grid operator to impose rotating blackouts because of higher power demand.

As of Tuesday afternoon,more than fourmillion people in Texas considered the energy capital of the U.S. still had no power as freezing temperatures rangingfrom -2 C to -22 C created a surge in demand for electricity to warm homes unaccustomed to such extreme lows, buckling the state's power grid.

The breakdown sparked growing outrage and demands for answers over how Texas whose Republican leaders as recently as last year taunted California over the Democratic-led state's rolling blackouts failed such a massive test of a major point of state pride: energy independence.

Weather forecasters predict more snow and ice late Tuesday and Wednesday along a storm front reaching from Texas to the Appalachian states.

Here's a look at how people are coping with the cold.

Staying warm

The worst outages were in Texas, with pockets in the state's largest cities, including San Antonio, Dallas and Austin, shouldering the lasting brunt of thecatastrophic failure. People lit fires and bundled up to stay warm.

Authorities in Houston saida woman and a girl died from suspected carbon monoxide poisoningat a home without electricity, where a car was running in an attached garage.

In East Dallas, brothers Alfredo and Eduardo Colon lost their power during the night at around 2 a.m. They spent the day huddled around a fire outside.

"It feels better out here than it does in there," Alfredo Colon said.

Helping out

Snowy, icy roads made for dangerous driving conditions. In the nearby state of Louisiana, police reported that it had investigated nearly 75 weather-related crashes caused by a mixture of snow, sleet and freezing rain in the past 24 hours.

For some in Oklahoma, driving wasn't possible at all until they had help digging out their vehicles.

Air travel was also affected. By mid-morning on Monday, 3,000 flights had been cancelled across the United States, about 1,600 of them at Dallas/Fort Worth International and Bush Intercontinental airports in Texas.

Stocking up

The power outages forced some Houston grocery stores to shut down, leavingpeople waiting in long lines to purchase supplies.

Alternative transportation

For some, a trip to the grocery store involved a long trudge through the snow-laden streets. At least one person could be seen riding a snowboarddown Congress Avenue in Austin, Texas.

The massive winter storm that immobilized the Southern Plains was heading to the eastern Great Lakes and New England, where heavy snow and freezing rain was expected Tuesday, the National Weather Service said.

The storm system left behind record-setting cold temperatures, and another wave of snow and ice was predicted late Tuesday and Wednesday along a storm front extending deep into the South.
