Points saillants

At the mid and upper elevations, hard slabs two to five feet deep still warrant concern for backcountry travelers venturing into very steep avalanche paths that did not slide during the last storm cycle. Larger triggers, such as snowmobiles, are more likely to impact these deep instabilities. As the day progresses, the likelihood of triggering these slabs on sunlit aspects will increase. The consequences of being caught in one of these slides could be fatal and caution is advised. At the lower elevations, the snowpack is mostly stable and avalanches are unlikely.

Avalanche Discussion

Wednesday looks to be mostly sunny with highs in the teens and light winds before a weak system brings the chance for some snow flurries or light snow Wednesday evening and night. The general avalanche hazard is Moderate. The chance persists for backcountry travelers to trigger pockets of slab to five feet in depth in steep rocky terrain. A larger trigger such as a snowmobile or a group of skiers may be needed to initiate failure although a slab could possibly fail even to one person if a shallow trigger point is impacted in very steep terrain.
