A storm gathering strength in Colorado's high country is expected to dump up to a foot of snow in parts of the Front Range and eastern plains, and already has forced the cancellation of 400 flights at Denver International Airport.
The National Weather Service said 7 to 11 inches of snow is expected in the Denver area Saturday, along with wind gusts nearing 30 mph.
DIA spokesman Heath Montgomery said travelers whose flights were not canceled can expect delays as crews deice airplanes.
Meanwhile, Mindy Crane with the Colorado Department of Transportation says 340 snowplows have been deployed across the Front Range, including 75 in the Denver metro area. Another 30 plows are working the Interstate 70 corridor from just west of Denver to Vail.
The Weather Service said Sunday will bring warmer temperatures and sunny skies.
