The biggest winter storm to hit the Denver area so far this season is making the morning commute a mess, causing many spinouts and crashes in the slippery snow and delaying flights by an average of about an hour and a-half at Denver International Airport.
A few flights between Seattle and Denver have also been canceled.
About 5 inches of snow are expected at the airport by the end of Tuesday but some areas could get up to 10 inches through the afternoon, when the storm will move into Nebraska and South Dakota.
Kids at schools in Denver and surrounding areas are getting a snow day. Many schools in South Dakota, including those in Rapid City, are shut down in anticipation of the approaching storm.
