Storm Closes All Highways in 6 Okla. Counties

The Great Plains region is being pounded by another massive winter storm, just days after a huge storm system dumped more than a foot of snow on some areas. The National Weather Service warns that the storm is bringing potentially "life threatening" and "crippling" conditions to parts of Kansas, Oklahoma, and the Texas panhandle, reports CNN. Flights have been canceled and residents have been urged to stay off the roads; indeed, in Oklahoma, six counties have closed all of their highways.

Almost all roads in the Texas panhandle are now impassible as well, and emergency crews are currently struggling to reach drivers who either didn't heed or didn't see the National Weather Service's explicit "DO NOT TRAVEL" warnings. National Guard units are being sent in to help. Forecasters say the storm system will also hit Southern states and could spawn tornadoes in Louisiana, Mississippi, Alabama, the Florida panhandle, and Georgia, the AP reports.
