Up to a foot of snow is expected across several states due to the winter storm, with ice accumulating farther south.

A powerful winter storm continued to disrupt daily life across Tennessee on Jan. 26, bringing snow, ice and dangerous travel conditions to much of the state.

As of 5:30 a.m., Monday, Jan. 26, nearly 13,000 people were without power as the storm moved through Oncor's service territory, the agency's outage map shows. Oncor's service area includes the majority of North Texas and parts of West Texas.

At least 13 people have died and hundreds of thousands across the US are without power as a winter storm sweeps through the country.

The winter storm is moving offshore but much of the eastern part of the country faces ice, bitterly cold temperatures and wind chill.

Officials are optimistic the power grid will hold, but freezing rain and arctic cold could cause localized electricity outages.
