OKLAHOMA CITY – Oklahoma Gas and Electric is reporting that power has been restored to the more than 30,000 customers who lost power Wednesday night as high winds and icy conditions moved across the state.

As of 10:30 a.m., there were no outages affecting more than 50 customers, according to OG&E's Web site.

An outage that knocked out power to 5,500 Yukon customers this morning forced Yukon schools to cancel classes, according to a message on the district's Web site.

Other metro school districts closed due to cold weather include Oklahoma City, Edmond and Putnam City. View a complete list of closings.

Temperatures will stay in the teens today. Wind chills are below zero for most of the state this morning.

The entire state is under a wind chill advisory.

Paramedics warn that frostbite and hypothermia can happen in just a matter of minutes.

"People need to realize this is serious. Bundle up for everything including quick errands," said EMSA Field Supervisor Tony McCarty.

The Oklahoma Department of Transportation reports that most roads are clear. Salt and sand trucks worked overnight as the freezing precipitation rolled across Oklahoma.

High winds and the salt trucks helped to dry roadways, but ODOT cautions that motorists should expect icy spots especially on bridges and overpasses.
