Tetons

Heavy snowfall overnight and continuing through the day is being moved by strong southwest winds to create easily triggered soft surface slabs one to two feet in depth on a variety of aspects. The new snow is falling on weak, light density snow and surface hoar. This sensitive load rests on sun crusts and wind pack. Natural or human triggered avalanches are likely on many aspects. Travel in avalanche terrain above 9,000 feet is not recommended. The size and sensitivity of the slides will increase through the day at all elevations. Steep slopes, road cuts and ravines should be avoided at low elevations.

Some light snow is expected tonight as the storm exists the area and as the cold front forces temperatures to drop to near zero degrees by morning. Winds are to diminish to near ten mile per hour averages overnight. Skies are to be partly cloudy during the day and temperatures are to rise only to the higher single digits. The general avalanche hazard is expected to be Considerable in the Southwest Trails area and in the high elevations of the Teton Area. It will be possible for humans to trigger soft slabs to depths of two feet in steep terrain in these areas. Pockets of similar slab exist at lower elevations of the Tetons. In the Togwotee area, the avalanche hazard is expected to be Moderate, where pockets of surface slabs to a foot in depth could be triggered in steep terrain.
