“Large and dangerous avalanches are likely,” the CAIC forecasters said, urging backcountry travelers to avoid avalanche terrain.
About 10 to 15 inches of dense snow piled up, with southwest winds building slabs at higher elevations. At all elevations and all aspects, the new snow sits atop layers of old persistent slabs and non-cohesive faceted kernels of snow at the base. Slides in the storm slab layer can step down into older snow, resulting in big avalanches potentially running long distances.

The Steamboat area has seen between 3 and 4 feet of snow in the past week, and high winds have built extensive windslabs on north to east to south aspects, where both triggered and natural slides are likely the next few days. Some of the avalanches will be large and destructive. Under the warning, travel is not recommended in avalanche terrain. Continue reading “Colorado: Avalanche warnings & watches in the backcountry”→
Snow Thursday night could set off another natural avalanche cycle
By Summit Voice
SUMMIT COUNTY — A round of forecast snow — perhaps 4 to 10 inches Thursday night — could unleash another cycle of dangerous, naturally running backcountry avalanches, Colorado snow safety experts said, issuing an avalanche watch that covers the Front Range and mountains to the west from Fairplay up to Steamboat Springs.
An avalanche watch means that, if the weather forecast is accurate, the avalanche danger will rise to high in the watch area, with both natural and triggered slides likely. The watch is in effect through 11 a.m. Friday. A high danger rating means very dangerous backcountry avalanche conditions, and travel in avalanche terrain is not recommended. Specifically, the warning covers the Park Elkhead, Flattop, Front, Gore and Tenmile ranges. Continue reading “Colorado: Backcountry avalanche watch issued”→
Fresh powder at all Colorado ski areas; large and dangerous avalanches expected in the central and southern mountains
By Summit Voice
SUMMIT COUNTY — In the last edition of the weatherblog, we asked, “Whither the jet stream?” Well, we got our answer Thursday night and Friday morning as a fire hose of steady snow set up across much of Colorado, delivering impressive snow totals around the state, with the biggest totals in the central mountains. Monarch reported a 26-inch storm total, while Crested Butte reported 22 inches. Click here for the full snow report.
That bullseye area is now under an avalanche warning valid through 12 p.m. Sunday (Feb. 27), where forecasters with the Colorado Avalanche Information Center are expecting a cycle of large natural avalanches on northwest to east-facing slopes.
The National Weather Service is maintaining a winter weather advisory for the northern mountains through 11 a.m. Sunday, as blowing snow will lead to dangerous driving conditions on some mountain roads and passes. Snowfall will taper off Sunday afternoon, but temperatures will remain cool under a northwest flow.
Highs for Sunday will stay in the teens and low 20s, warming just a bit on Monday. Another shot of moisture with a chance of light snow is forecast for Monday night. Northwest flow remains over the area for the next few days with on and off chances for snow showers. Continue reading “Weatherblog: Valentine’s Day freshies”→
