    Loose wet avalanches will become possible on E-SE-S-SW-W aspects at all elevations as daytime warming occurs.  Colder overnight tempertures with clear skies, and northerly winds today should prolong the window of supportable snow.  As the snow surface becomes wet and deep, it is time to move to a colder aspect or to leave the area.  Steep slopes and terrain traps can magnify the consequences of even small loose wet activity.

Avalanche Discussion

Observations were received from Angora Peak (Echo Summit area) and National Geographic Bowl (Squaw Valley area).  Rapid warming was reported at both locations.  Little to no snow surface refreeze was observed on tree covered slopes at 8am on Angora Peak.  In open areas, good travel conditions existed at 10:15am with spring type snow conditions.  Small loose wet activity was starting to occur on Angora Peak during this time frame.  Large cornices, glide cracks, and creek crossings were additional hazards noted.
