Tetons

Avalanche activity is unlikely today as cooler temperatures, increasing cloud cover and gusty winds will keep snow surfaces frozen, and the snowpack is mostly stable. Isolated small pockets of wind slabs on steep, high elevation slopes will be difficult to find, but if encountered could have consequences in extreme terrain. Variable snow surfaces will create challenging travel and on steep slopes firm snow could present slide for life conditions.

The incoming system, although weak, will at least bring a change in the weather and some accumulating snow. Expect snowfall to start by 5am and end during the evening. Four to six inches could fall in the Teton area during that time with slightly lesser amounts in the other forecast areas. Southwest to west winds are to be light during this event with 10-15 mph averages. Temperatures are to be relatively uniform with all elevations starting near 20 degrees in the morning, rising into the upper twenties in the afternoon. The general avalanche danger is expected to be Low throughout the day due to limited accumulation and light winds in the forecast. This new snow will fall on hard and slick snow surfaces on a variety of aspects and elevations. Very small wind slabs could start to form by the afternoon and if actual snowfall exceeds forecast amounts, the danger could increase to Moderate. Check the morning forecasts for updated danger ratings and details. Backcountry travelers are encouraged to remember that on steep slopes with a sustained pitch, even a couple inches of moving snow can pick up enough volume to knock someone over and carry them into unforgiving terrain.
