Lo esencial

At the mid and upper elevations, backcountry travelers might be able to trigger persistent slabs up to four feet deep on steep avalanche prone slopes. Avalanches are less likely at the lower elevations, but could still be triggered with depths to one foot in steep terrain.

    Persistent slabs lie upon weak, faceted snow and hard snow surfaces which formed during the January dry period. There is a high degree of spatial variability associated with these weak layers, which makes it difficult to predict how a slope will react to the presence of skiers or riders. Adjacent slopes with similar aspects could have varying conditions. Evaluate the snow and terrain carefully, and identify features of concern.

Avalanche Discussion

Light density snow is expected to fall from mostly cloudy skies overnight and through the day on Wednesday. Accumulations of several inches are likely overnight and again on Wednesday. Winds will be northwesterly at 15 to 20 miles per hour and will easily transport the new light density snow onto leeward aspects along the higher ridge crests. Temperatures will be in the single digits and teens in the mountains and rise into the 20s in the valleys.Unstable conditions persist and the hazard is expected to be increasing. Soft slabs up to three feet in depth lie upon persistent weak layers of faceted snow and could be human triggered on steep slopes in all of our forecast areas on a variety of aspects and elevations. Natural avalanches are possible especially in the Greys River/Southwest Trails Forecast Area where the general avalanche hazard is expected to be CONSIDERABLE. A MODERATE but increasing avalanche hazard in expected in the Teton and Togwotee Pass/Continental Divide Trails areas.
