Roads in eight northwest Oklahoma counties are still closed or considered hazardous, but the Oklahoma Department of Transportation says there are almost 600 plow and truck drivers working to clear Monday's heavy snowfall.
The highways affected include U.S. Highway 64 west from Alva and U.S. 60 between Seiling and Vici.
All roads in Woods County are either snow-packed or hazardous.
The Department of Transportation says wind is blowing snow back onto some cleared roads but the sun is helping.
Several road clearing crews have been brought in from Southern Oklahoma to help.
