Driving conditions across Colorado, particularly in the southeast, will be dangerous throughout the day as a winter storm blows through the state.

The Colorado Department of Transportation had 451 snow plows working to clear roads as of 8:30 a.m. Saturday.  Southeast Colorado roads were icy, with blowing snow reducing visibility. Traffic cameras throughout the area showed snow accumulation on highway surfaces, though few closures have been reported. 

The east- and westbound lanes of Highway 287 just west of Eads in Kiowa County were blocked by a jackknifed semi tractor-trailer around 6:30 a.m., however traffic was able to pass on the highway shoulders. The highway has since reopened.

In Las Animas County, another semi was stuck, forcing the closure of southbound Interstate 25 two miles south of Trinidad. The Highway remained closed as of 8:30 a.m.

A winter storm warning is in effect for Kiowa, Prowers, Baca, Bent, Crowley and Otero counties until noon Saturday. The warning also covers the eastern half of Las Animas County. The National Weather Service predicts 4-8 additional inches of snow to fall in the area. Winds are expected to gust up to 55 miles per hour through the day.

Further north, Cheyenne, Kit Carson and Yuma counties are under a blizzard warning until 11:00 p.m. Saturday as an additional 3-8 inches of snow falls and winds gust to 50 mph. Blizzard conditions extend across most of Kansas as well as the Oklahoma panhandle.
