Highlights

Riders and skiers have the chance to trigger new soft slab avalanches and older slabs in steep terrain. In areas where significant new snow fell over the past two days, wind slabs could be triggered. Older, persistent slabs could also be triggered that vary in depth from one to four feet, with the deeper slabs possible at the higher elevations. Evaluate the snow and terrain carefully, and identify features of concern.

    Backcountry travelers could trigger recently developed wind slabs with depths up to one foot in steep, wind loaded terrain.

    Persistent slabs lie upon weak, faceted snow and sun crusts formed during the January dry period. There is a high degree of spatial variability associated with these weak layers, which makes them difficult to predict. These slabs may be soft or hard and could be triggered by backcountry travelers in steep, avalanche prone terrain with depths of a foot at the lower elevations to four feet at the higher elevations.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Expect mostly cloudy skies and a chance for light, scattered snow showers tonight and into Sunday. Cloud cover will decrease Sunday afternoon. Overnight lows in the mountains will be in the single digits rising into the low teens during the day. Northeasterly ridgetop winds will range from 10 to 20 miles per hour.The General Avalanche Hazard is expected to be MODERATE on Sunday. Backcountry travelers venturing into steep, avalanche prone terrain could trigger slides up to four feet deep. These slabs lie upon weak, faceted snow and sun crusts formed during the January dry period. There is a high degree of spatial variability associated with these weak layers, which makes them difficult to predict. In some areas the new snow is bonding well to the January surfaces, but that is not the case everywhere. Evaluate the snow and terrain carefully, and identify features of concern.
