Tetons

During the past four days up to eight inches of new snow has fallen in favored locations. This snow accumulated upon areas of surface hoar. Winds have been from mostly from the west-southwest to west-northwest during the past several days and have been strong enough to move some of this new snow along the highest ridge crests. At the upper elevations some isolated pockets of wind slab up to a foot in depth may be reactive to human triggers in very steep terrain. Caution is advised as even a small slab avalanche can cause serious injury during these early season conditions. Snow cover tapers from depths of one to two feet at the upper elevations to depths of less than six inches and areas of bare ground at the lower elevations

A broad upper trough is centered over the Gulf of Alaska. Skies are expected to be mostly clear tonight and mostly sunny again during the day. Temperatures are expected to become inverted with overnight lows in the single digits in the coldest valley locations. Daytime highs will rise into the 20s and 30s at all elevations. Winds will be light at less than 15 miles per hour and back from the west to the south.At the upper elevations small, isolated pockets of wind slab up to a foot in depth could be sensitive to human triggers in very steep terrain. The general avalanche hazard is LOW and normal caution is advised as even a small slab avalanche can cause injury during these early season conditions. Avalanches are unlikely at the mid and lower elevations.
