The avalanche danger is Moderate in the upper elevations today. New snow and winds have formed slabs that may be sensitive to human triggers. Loose snow avalanches will also be of concern in steep sustained upper elevation terrain. At the mid elevations isolated pockets of wind slab may be encountered on steep leeward slopes. At the low elevations avalanches are unlikely. Approach avalanche terrain cautiously today and be on the lookout for signs of unstable snow including recent avalanches, shooting cracks, and whoompfing. Travel one at a time in suspect areas, utilize islands of safety and communicate plans within your group.
Up to a foot of new snow accompanied with strong southwest winds have formed slabs up to 2 feet in depth. These slabs will be more sensitive in the higher elevations and on steeper slopes with firm and slick underlying bed surfaces.
Isolated snow showers will continue overnight with minimal accumulation expected. A trace to an inch of snow is possible in all three forecast areas. Winds will be light, in the 10-15 mph range out of all directions. A cold air mass that has moved its way into the central part of Wyoming will make its way west over the Continental Divide overnight. Temperatures at 8,000-9,000 feet will drop into the negative single digits overnight and only rise to the (positive) single digits during the day.While this storm progressed in a way that favors a quick improvement in stability, the possibility remains for human triggered wind slabs and dry loose avalanches in steep upper elevation terrain. It will be important to carefully assess the snowpack in this terrain prior to committing to a particular slope. In the upper elevations the danger will remain Moderate. In all other terrain avalanches will be unlikely and the avalanche danger will remain Low.
