Highlights

The general avalanche hazard is CONSIDERABLE above an elevation of 7,500 feet and MODERATE below that elevation. Three to four foot deep slabs were triggered yesterday by riders on a steep east facing slopes in the Wyoming Range. Large persistent slabs will slowly gain strength but could still be human triggered on a variety of aspects, especially by larger triggers such as snow machines. These slabs are expected to remain unstable on some slopes for days or weeks. Although these dangerous slabs could be triggered in the early morning hours, they will be more sensitive to failure during the warmer portion of the day. Expert knowledge and patience are essential for safe travel in avalanche terrain today.

    Large persistent slabs could be human triggered on a variety of aspects. At the mid and upper elevations these slabs could have crown depths of two to five feet. At the lower elevations these slabs could have crown depths of one to three feet. They have been triggered by skiers and riders in areas where thick deposits of wind-drifted snow exist in avalanche starting zones. Shallow, weak spots in these slabs on steep rocky slopes should also be considered likely trigger points. Previous tracks on a slope should not be mistaken as an indication of stability. These slabs will become more sensitive to human triggers during the warmer portion of the day. Persistent slabs warrant a patient approach to safely navigate potentially suspect terrain.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Skies will be clear. Temperatures will be inverted. Overnight lows will drop into the teens at 10,500 feet and to around zero in the valleys. Daytime highs will rise into the 20s and 30s. Winds will be light and variable.Large persistent slabs with depths of two to five feet could be human triggered on a variety of aspects at the mid and upper elevations where the general avalanche hazard will be CONSIDERABLE. Persistent slabs with depths of one to three feet could be human triggered at the lower elevations were the general avalanche hazard will be MODERATE.
