Tetons

Overnight temperatures remained above freezing up to 9000 feet. Although in the early morning the avalanche danger will be Low, warm temperatures and periods of morning sunlight followed by rain will quickly further weaken the snowpack and the avalanche danger will increase. At the high elevations pockets of dense and possibly wet slabs to two foot depths could be human triggered in very steep terrain. At the mid and low elevations wet loose and wet slabs could release naturally in very steep avalanche terrain features. During the mid afternoon yesterday, a skier triggered and was carried by a two foot slide on Albright Peak in Grand Teton National Park.

In the mountains, expect two to four inches of new snow overnight as a cold front moves through the region. Snow showers will continue through the day with an additional one to three inches by the evening. Rain or a rain/snow mix will be possible in the valleys. Overnight lows in the mountains will be in the mid to upper teens before rising into the low 20s during the day. Valley temperatures should dip below freezing during the night and then climb into the low 30s during the day. Southwesterly ridgetop winds will veer to the west at 25 to 35 miles per hour overnight, and then decrease to around 20 during the day.At the higher elevations, the general avalanche hazard is expected to be LOW Sunday morning and could rise to MODERATE during the day as new soft slabs form on slick sliding surfaces. Backcountry travelers could trigger these six to twelve inch slides in steep, wind loaded terrain. At the lower elevations, any extended periods of rain could increase the hazard to MODERATE and bring about the possibility of wet loose slides.
