The General Avalanche Hazard is LOW at all elevations this morning, and could rise to MODERATE during the day depending on the amount of sun impacting the snowpack. Any extended periods of sunshine this time of year can rapidly warm the upper snowpack and wet, loose slides can result. These slides may be started by backcountry travelers, snow falling off cliff areas, or cornice collapses.
Avalanche Discussion
A weak system moving across the area could produce a few snow showers tonight, but with little accumulation. During the night and into Thursday, winds should increase to near 30 mph out of the Southwest. Overnight lows are expected to dip into the mid 20s in the mountains, and near freezing in the valley, before rising into the 40s up high and 50s down low. Skies should be mostly to partly cloudy.AVALANCHE HAZARD FORECAST FOR THE TETON, TOGWOTEE PASS, AND SOUTHWEST TRAILS AREAS:The General Avalanche Hazard tomorrow morning is expected to be LOW at the mid and upper elevation and MODERATE at the low elevation, before rising to MODERATE at all elevations in the afternoon. Below freezing overnight temperatures will temporarily lead to a stabilizing trend at the mid and upper elevation. The hazard will raise proportional to the amount of heat and sun absorbed by the snowpack during the day.

These slides may be started by backcountry travelers, snow falling off cliff areas, or cornice collapses.
