The Oklahoma Highway Patrol has closed all highways in the state's Panhandle area, citing blizzard conditions.
Trooper Betsy Randolph says roadways in the area are slick and hazardous and visibility is extremely limited. The closure extends from Cimarron County eastward to Woodward County.
The highway closings don't have a definite expiration time, but Randolph says the patrol has advised its non-essential personnel that they might not come back to work until Wednesday.
