Tetons

The general avalanche hazard is Low at the mid and high elevations. In areas where old snow lies, new and recent snow could be triggered as loose snow sloughs or small soft slabs in isolated areas. This hazard will increase as more snow arrives today. The old snow, which is deepest in higher, northerly terrain, is comprised of crusts and well developed faceted snow, including surface hoar. This basal snow will continue to be a concern as the snowpack grows but has seen limited loading in the Tetons at this time. At low elevations, snow depths remain too low for avalanche production.

Another round of snow is expected between midnight and 8 am, followed by periods of light snow through Thanksgiving Day. Temperatures are to be warmer, with upper elevations reaching into the twenties, while valleys reach just into the thirties. Summit winds are again to be from the southeast to south with ten to twenty mile per hour averages. The general avalanche hazard is expected to be Moderate throughout western Wyoming above 9000 feet where wind formed soft slabs will be sensitive to human triggers in steep terrain that is underlain by old snow. These slabs will be most likely to be found on northeast, north, and northwest slopes. Below 9000 feet, the hazard will be Low, as less recent snow has fallen and the old faceted snowpack is much less prevalent. At even lower elevations, very little snow lies on bare ground.
