Tetons

In the last 24 hours, 10 to 14 inches of new snow fell at the mid and upper elevations, and 6 to 8 inches at the lower elevations. Backcountry travelers could easily trigger soft slabs and loose snow sluffs in steep terrain. These potential avalanches, which lie upon excellent sliding surfaces, will entrain significant amounts of loose snow and could carry skiers or riders long distances. Any warming events of the snow surface, such as brief periods of sunshine or scattered rain showers, will further destabilize the snowpack making natural activity more likely, particularly at the lower elevations.

Snow showers will continue until midnight then high pressure will begin to build over the region Tuesday with partly cloudy skies and temperatures rising from morning lows near ten degrees into the low twenties in the afternoon.In the Tetons increased winds Monday night will help firm up slabs to three feet in depth on lee slopes at upper elevations. The slabs will be easily triggered Tuesday or run naturally. Any periods of sunshine will rapidly weaken the snow surface and natural or human triggered slides will become more likely. The avalanche hazard is expected to be Considerable.In the Greys River area six to eight inches of new snow carries the chance of sloughs being triggered on steep slopes at higher elevations. The hazard there will be Moderate Tuesday.In the Togwotee Pass area there has been less snow and wind and the hazard there will be Moderate with a chance of surface sloughs on steep, lee slopes at higher elevations.
