DENVER -- Airlines canceled nearly 200 flights at Denver International Airport as the biggest snowstorm in more than a year moved into the Denver metro area and along the Front Range.
The Federal Aviation Administration implemented a ground delay to space out arriving planes into DIA. Delays were averaging roughly 57 minutes, as of 3:30 p.m.
Travelers should check their flight status before traveling to the airport.
Two car crashes were reported on outbound Pena Boulevard near the airport terminal, airport officials said.
The condition of the occupants of the vehicles are unknown, but DIA instructed travelers to "drive with care as roads are slick."
Crew were out overnight clearing and treating runways. Blowing snow was reducing visibility, officials said.
All airlines will deice planes for the duration of the storm.
