Wet Slab Avalanches

By  | 

With temperatures reaching 70 degrees and beyond in many parts of the state today, there were at least five wet slab avalanches.

Wet slab avalanches are most likely to occur during warm weather when the snowpack doesn't freeze hard during the night. It creates instability between the layers of snow, leaving the lower layer unable to support the layer above.

A 30-foot-wide, three-foot-deep slide on Loveland Pass had Highway Six closed for about an hour this morning. It broke away at about eleven-thousand-200 feet and covered the highway about a mile-and-a-half below Arapahoe Basin Ski Area.

Colorado Department of Transportation spokesman Bob Wilson says a second avalanche hit Highway 91 south of Copper Mountain Resort, reducing traffic to one lane.

Slides also were reported around Battle Mountain near Minter, Berthoud Pass in Grand County and Highway 50 over Monarch Pass.

Cooler temperatures forecast for tomorrow are expected to reduce the activity.
