Southwest has canceled 201 flights, about 49 percent of its scheduled flights. Skywest has canceled 156 flights, about 53 percent of its flights. United also began canceling flights and was up to 191 flights which is about 47 percent of its flights.

Travelers are urged to check with their airline before heading to the airport to check the status of their flights. Heavy blowing snow expected on Wednesday night could lead to poor visibility on Peña Boulevard. The airport encouraged passengers to utilize RTD commuter rails or buses rather than driving to the airport. 

During the bomb cyclone that hit Colorado in March, more than 1,400 flights were canceled in and out of Denver. During that storm, the airport closed all six of its runways due to extremely low visibility on the airfield. 

It was only the fourth time in the airport's history that all runways were closed. It was more than 24 hours before all of them were back open.
