The Latest on winter weather across the U.S. (all times local):
At least 35 deaths have been attributed to days of severe winter weather in the United States. Traffic accidents have claimed the most lives, followed closely by the carbon monoxide poisoning of people using vehicles or generators to stay warm.
A half dozen people have died from exposure, including several whose bodies were found along Texas roadways covered in ice and snow, and a Kentucky woman in an unheated mobile home.
A house fire killed a grandmother and three children whose mother and friend were injured after flames escaped a fireplace in Texas. Three people died in a tornado in North Carolina. Three more fell through ice, into a pond in Tennessee, a lake in Oklahoma and a swimming pool in Louisiana.
And a 9-year-old boy was killed while having fun with his father in Tennessee. His dad was pulling him on a tube behind an ATV on an icy street when the boy slammed into a mailbox.
BIRMINGHAM, Ala. - More than 320,000 homes and businesses were without power in Louisiana, Mississippi and Alabama early Thursday after a wave of storms dumped as much as 4 inches of snow and ice across a region that still had some remnants of wintry precipitation left over from earlier in the week.
Dozens of school systems canceled classes, switched to online learning or opened late, and conditions might not improve much in some places until Friday afternoon, when temperatures are finally supposed to rise above freezing for a few hours.
The largest concentration of outages was in a band across central Mississippi. Much of the rest of the Deep South was spared the worst weather.
NASHVILLE, Tenn. - Twelve people have been rescued from boats after a dock weighed down by snow and ice collapsed on the Cumberland River in Tennessee, the Nashville Fire Department said.
Fire crews and the Office of Emergency Management responded Wednesday evening to the Blue Turtle Bay Marina after a report that people were trapped in multiple boats when the roof over the dock collapsed, authorities said.
Nashville Fire Department spokeswoman Kendra Loney told news outlets that everyone known to be on the dock was accounted for and no one was injured. She said the weight of the ice and snow on the roof of the dock caused the collapse.
BATON ROUGE, La. - Gov. John Bel Edwards wrote President Joe Biden on requesting a presidential emergency declaration for Louisiana, citing three deaths and thousands without electricity and water in the severe cold.
Edwards said the "extreme winter weather, including record low temperatures, snow, sleet and freezing rain, has been destructive for many areas of Louisiana, most notably through continued power and water outages across the state."
The Democrat said federal assistance would be particularly welcome in communities still recovering from last year's hurricanes. He said nearly a million Louisianans are having to boil their water, more than 48,000 Louisianans lack water altogether, and thousands remain without power.
OKLAHOMA CITY - Oklahoma Gov. Kevin Stitt said Wednesday that he is asking President Joe Biden for a federal disaster declaration as a result of a winter storm that dumped snow and ice on the state in addition to days of subfreezing temperatures and power outages.
Stitt's disaster declaration request for all 77 Oklahoma counties comes a day after the governor spoke with Biden by phone.
"President Biden pledged the federal government's support for Oklahoma when we spoke by phone," Stitt said. "I am now urging the president and his administration to act quickly and deliver on our request to help Oklahomans recover from this historic storm." Stitt declared a statewide emergency last Friday as the winter storm was approaching the state.
