A powerful late winter storm hit the central Rocky Mountains Sunday with heavy snow and wind, leading to airport and highway closures, power outages and avalanche warnings in parts of Colorado, Wyoming and Nebraska. The storm dumped anywhere from a foot to 40 inches on the Denver metropolitan area, according to CBS News weather producer David Parkinson, making it the fourth biggest in Denver history.

At Denver International Airport, runways were closed just before noon due to blowing snow and poor visibility. The airport got roughly 27 inches, the National Weather Service Boulder, Colorado office tweeted.

Parkinson said there would be little to no melting Monday, meaning people would have lots of heavy, wet heavy snow to dig out from. It stopped SUVs, police cars and even plows yesterday, Parkinson said.

As of 7 a.m. EDT Monday, some 25,000 homes and businesses were without power, according to poweroutage.us.

At one point, Aurora, Colorado police tweeted that there were 48 calls pending for stuck motorists, adding that, “The road and weather conditions are so poor that even some of our first responders are waiting for assistance.”

An avalanche warning was in effect Sunday for the Rockies west of Fort Collins, Boulder, Denver and Colorado Springs, where “intense snowfall will cause large and destructive avalanches,” the Colorado Avalanche Center said. The center warned that avalanches could happen in unusual locations and recommended against traveling in the backcountry.
