Snowmobilers could trigger dangerous hard slab avalanches in isolated areas. Shallow wind slab avalanches could also be triggered by riders or skiers on steep slopes with recent deposits of wind blown snow.
Some potential could remain for snowmobilers to trigger deep hard slabs in isolated areas where weak faceted snow persist near the base of the snowpack. These dangerous slabs could have depths to five feet.
Slab avalanches up to two feet in depth could be triggered by riders or skiers who venture into very steep terrain and cliff areas.
( Discussion is generated from the previous day's afternoon forecast. )A warm front in a southerly flow will bring some mountain snow showers and valley rain showers to the region overnight. This flow will favor the Salt River, Snake River and the Wyoming Ranges. Several inches of new snow accumulation are possible by sunrise at the higher elevations. Snowfall will continue into Wednesday morning and is expected to diminish during the day. Winds will be light and variable and temperatures will be in the teens and 20s. The general avalanche hazard is expected to MODERATE at the mid and upper elevations where dense slabs up to two feet in depth could be human triggered in very steep active avalanche paths and cliff areas. The hazard is expected to be LOW at the lower elevations.
