The brunt of a winter storm sweeping across the Rockies has been seen mostly in the south and east of Colorado, with much of Colorado's main east-west highway closed because of blizzard conditions on the state's Eastern Plains.

A blizzard warning remains in effect for northeastern Colorado through 2 p.m. One for areas south of Denver expired at 11 a.m. Weather watchers reported drifts of up to 2 feet in Elizabeth, east of Castle Rock.

I-70 was closed from Denver to Burlington, near Kansas. Chad Gimmestad, senior forecaster at the National Weather Service, said the snowstorm has tapered off in the metro area, but it will take "all day" to move out of the state.

"Areas from around Franktown, out across Elbert County, toward the Limon area, some places had over a foot of snow and 50 to 60 mph winds," he said. "There’s still going to be heavy snow out on the plains."

Massive snowfall and high winds have prompted an avalanche warning for Southwestern Colorado.

Scott Toepfer, with the Colorado Avalanche Information Center, says all of that snow is stressing the snowpack in Colorado and has “increased the avalanche danger significantly over what it was just on Sunday.”

“When we issue an avalanche warning we recommend that people not go riding in the backcountry, whether it's snowboarding, skiing, snowshoeing, snowmobiling any of those hobbies,” he cautioned.

The warning covers the San Juan Mountains. Avalanches are most likely in alpine regions, but could grow large enough to reach valley floors. The warning expires at noon Wednesday.

Ski areas in the mountains saw some decent accumulation. Vail reported 8 inches, with areas further east receiving slightly less.

Boulder reported a scant few inches. Fort Collins received light rain. Four inches of snow fell at Denver International Airport. The airport said 130 flights were canceled Tuesday.

Aurora, Douglas County and Cherry Creek schools closed for the day; Denver schools were open, but some were delayed.

Denver is forecasted to warm up to 40 degrees, and may even see some sunshine by the afternoon. Warmer, drier conditions are expected through the end of the week.
