Tetons

Overnight lows were a few degrees warmer than yesterday, and surface crusts may be less developed. If mostly clear skies persist into late morning, the general avalanche hazard could increase from LOW to MODERATE before mid-day once snow surfaces soften. This scenario brings a possibility for wet loose slides and cornice failures. These events, along with backcountry travelers, could also trigger pockets of surface slab up to 18 inches deep. If cloud cover comes in early and surface crusts remain frozen, mostly stable avalanche conditions could continue throughout the day. Monitor the warming of the snowpack, stay out from under large cornices, and plan to avoid avalanche terrain if snow surfaces significantly soften.

Expect mostly cloudy skies overnight, along with mountain snow showers, as an upper level trough moves over the area. The chance for new snow will decrease during the day. Overnight lows up high will be in the upper teens before rising into the mid-20s in the afternoon. Southwesterly ridgetop winds will shift to the northeast at 10 to 20 miles per hour.The general avalanche hazard is expected to be LOW Sunday morning. Isolated pockets of very shallow new wind slab may develop overnight and into Sunday. This blanket of new snow, along with colder temperatures and cloud cover, should keep old snow surfaces frozen. Monitor conditions, and move to a cooler aspect if surface crusts begin to break down.
