SUMMIT COUNTY, Colo. (CBS4) – Video of an avalanche rumbling across Interstate 70 early Friday afternoon served to validate experts’ warnings about the increased danger of high-country snowslides this weekend.
This as a new storm system arriving Sunday threatens to release additional accumulation on weakly connected layers of deepening snow.
Initial small slide impacting WB lanes, however, area needs to be cleared.

David Roth was driving westbound on I-70 just after 1 p.m. Friday when the slide billowed downhill and across the roadway. By the end of the recording, the snow cloud had reached Roth’s vehicle.
Less than a year ago, Colorado travelers experienced record-setting avalanches along the same stretch of I-70, referred to as Tenmile Canyon.
The northern and central mountains of Colorado saw the greatest impact. Ski areas near the slide measured two-and-a-half feet of new snow from the most recent system.
Forecasters from the Colorado Avalanche Information Center placed the avalanche danger in those areas at a Level 4 out of 5 Friday. It remains high through Saturday. Kreston Rohrig of the CAIC posted a Youtube video on Thursday, prior to the system’s arrival, describing the “weak facets” of the snow layers along Vail Pass.
“Digging here was like digging in a sandbox,” Rohrig said of the granular snow. “Really weak.”
Five to ten more inches of snow is expected in the mountains from Sunday’s incoming system.
