The general avalanche hazard is MODERATE above 9,000 feet and LOW below that elevation. At the higher elevations, the chance continues to trigger deep instabilities in the snowpack in a few steep avalanche paths. Avalanches below 9,000 feet are not expected today.
Layers of weak faceted snow are buried in the snowpack. At the upper elevations, hard slab avalanches with depths to three feet could be triggered by snowmobilers in steep, avalanche-prone slopes that face north through southeast.
( Discussion is generated from the previous day's afternoon forecast. )Dry conditions are expected overnight and into the morning hours on Tuesday. A weak disturbance could move in during the afternoon and evening and bring several inches of new snow to the higher elevations by Wednesday morning. Temperatures are forecast to fall into the teens tonight and rise into the 20s in the mountains and into the 30s in the valleys during the day. Winds will be light and variable.The snowpack is mostly stable with a few concerns at the upper elevations in all three of our forecast areas. In the Teton Range, isolated pockets of shallow wind slab less than foot in depth could be human triggered in very steep terrain at the upper elevations. In the Greys River area there are isolated locations at the upper elevations where some potential to trigger deep slab avalanches may persist. In the Togwotee Pass area some potential may also persist for snowmobiles to trigger deep hard slab avalanches in some steep upper elevation avalanche paths. The general avalanche is expected to be LOW in the Teton area and MODERATE in the Greys River and Togwotee Pass areas.
