Travel conditions around the state are expected to deteriorate the rest of the day and into the overnight hours as wintry precipitation continues to fall all over Oklahoma.

Northwestern Oklahoma received the most snowfall with an additional 2 to 5 inches of snow today adding to the 2 to 4 inches those counties received Friday.

Oklahoma Department of Transportation (ODOT) crews continue to plow and treat highways with a sand and salt mixture. Those crews will continue to treat the roads until they're dry and safe for travel.

Roads in Cimmarron County, at the tip of the panhandle, are dry and drivable, but conditions from Texas County east to Woodward and Ellis counties are snow-packed and hazardous.

Light-to-moderate snowfall across both the Oklahoma City and Tulsa metro areas is adding to the slick and hazardous nature of highways and interstates in these areas. Crews continue to battle slick spots and motorists are urged to use extra caution on bridges, ramps and overpasses.

The eastern and central portions of I-40 are slick and hazardous with crews working in round-the-clock shifts to plow and treat the roadway. Similar conditions exist along I-35 with one lane kept clear by crews in each direction as they continue to plow and treat the additional lanes. Drivers should remain alert to trucks working statewide, and stay at least 200 feet behind.

With more precipitation forecast to fall across the state, road conditions will continue to change. Unnecessary travel is discouraged. Those who must be on roadways are urged to give themselves extra time, allow ample room for braking and drive for the conditions.

Black ice conditions will continue to be a concern in many areas of the state, especially as more freezing precipitation falls later on Saturday.

If drivers must travel out of state, they are urged to check area road conditions before heading out.
