DENVER (KDVR) — Hundreds of flights coming in and out of the Denver International Airport were either canceled or delayed due to a snowstorm Saturday.

Saturday is a Pinpoint Weather Alert Day, with a winter storm warning in effect for the Denver metro area until around noon Sunday.

Several roads were closed in the mountains and along the foothills for snow removal operations, crashes and hazardous conditions.

The same was true for air traffic; 871 flights coming in or out of Denver were delayed as of 10 p.m., according to Flight Aware.

An additional 86 flights at DIA were canceled. According to Flight Aware, 61 of the flights canceled were SkyWest.

The airport warned passengers in a post on X, formerly known as Twitter, to check with their airline concerning their flight status before heading to the airport.
