Metro Denver, Boulder Weather Forecast: Storm Warning Continues

While snow plows are out working to clear main arteries and residential streets, conditions in metro Denver and Boulder remain hazardous, weather officials said. Many roads are snow covered and slippery.

"Travel could be very difficult. Patchy blowing snow could significantly reduce visibility. The hazardous conditions could impact the morning or evening commutes," the National Weather Service warned in an alert. "The cold wind chills as low as 15 below zero could result in hypothermia if precautions are not taken."

Wednesday classes are canceled for Denver Public Schools, Aurora Public Schools, Adams 12 Five Star Schools, Adams County District 14, Douglas County School District, Cherry Creek School District and Littleton Public Schools. Schools in the Jeffco Public Schools and Boulder Valley School District will start two hours late, officials said.

Big plow operators were on duty overnight into Wednesday morning in Denver and dropped de-icer as needed. Plow drivers were also working to prevent deep ice rutting.

Hundreds of flights have either been delayed or canceled at Denver International Airport.

Police and weather officials warned drivers to be vigilant after dozens of crashes Tuesday throughout metro Denver and Boulder. The Colorado Department of Transportation closed Interstate 70 from Airpark Road to Limon in both directions on Tuesday at noon.

"If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency," National Weather Service officials warned.

Students across metro Denver were released early from school Tuesday afternoon. Jeffco School District and Boulder Valley School District chose to release students at normal dismissal times. Many city offices also closed early.
