Tetons

Last night's cold front brought 3 to 6 inches of new snow to the mountains. This new snow lies upon hard old snow surfaces. Shallow loose snow sloughs involving this new snow are possible on very steep slopes. At the higher elevations skiers and riders who venture into steep avalanche starting zones may encounter isolated pockets of wind slab that are less than a foot deep. Watch out for unstable snow on isolated terrain features. Even small slides can have consequences in extreme terrain.

Conditions will be dry until another cold front passes through the area tomorrow night. Under clear skies, temperatures will fall into the teens and 20’s. Daytime highs will be in the 30’s and 40’s in the mountains and in the 50’s in the valleys. Clouds will begin to increase in the afternoon ahead the cold front. Westerly winds will increase to speeds of 20 to 30 with gusts to 45 miles per hour. The snowpack is mostly stable, and the general avalanche hazard is expected to be low. The wet snow avalanche hazard will increase as the day warms. Shallow wet loose slides are possible on very steep sunlit aspects during the warmest portion of the day. Isolated pockets of shallow wind slab up to a foot in depth could be triggered by ski and snowboard mountaineers on very steep slopes at the highest elevations.
