Togwotee Pass

A passing cold front brought 6 to 12 inches of new snow to the higher elevations. This system favored the west slope of the Continental Divide and the northern portion of this forecast area. This new snow has accumulated on firm old snow surfaces. Loose snow sloughs could be triggered by humans on very steep slopes or release naturally on steep sunlit aspects. These sloughs and isolated pockets of wind slab up to a foot in depth pose a hazard to skiers and riders who venture onto very steep slopes and into cliff areas. Watch out for unstable snow in isolated terrain features.

( Discussion is generated from the previous day's afternoon forecast. )Expect a final burst of precipitation this evening as a cold front associated with the aforementioned upper level disturbance moves through the region. The mountains in the northern portion of the forecast area should receive an additional two to four inches of new snow while only an inch or two is expected in the Southwest Trails area. Skies will be on a clearing trend after midnight and mostly sunny to partly cloudy skies should persist into the afternoon if not throughout the entire day. Overnight lows in the mountains will drop into the low teens before rising into the low 20s in the afternoon. Valley temperatures will fall into the low 20s by the early morning hours before climbing to near 40 during the day.The general avalanche hazard is expected to be LOW on Monday. With substantially colder temperatures and partially clearing skies overnight, strong crusts should develop by sunrise, and avalanche activity will be unlikely below these crusts. As the day warms, shallow wet loose slides involving the new snow will be likely on steep, sunlit aspects. In high elevation terrain that is mostly to fully shaded from the sun, skiers and riders might be able to trigger an isolated pocket of shallow wind slab in very steep, wind-loaded terrain. Up there, loose snow sluffs will also be possible.
