Points saillants

Low avalanche danger this morning will increase to Moderate avalanche danger due to loose wet avalanche problems.  Loose wet avalanches will become possible at all elevations as daytime warming occurs.  Avoid slopes with deep, wet, and unsupportable snow.

    Loose wet avalanches will become possible on E-SE-S-SW-W aspects as daytime warming occurs.  If afternoon rain materializes, loose wet avalanche activity could become more widespread on all aspects.  Avoid areas with deep, wet, and unsupportable snow.  Even small loose wet avalanches can have consequences in steep terrain or where terrain traps exist.

Avalanche Discussion

Observations were made and received from Jakes Peak (West Shore area), Negro Canyon (Donner Summit area), and Flagpole Peak (Echo Summit area).  All areas reported warming conditions through the day with decreasing winds.  Supportable crusts existed in the morning with good travel conditions before becoming unsupportable wet snow by the mid day.  Minor skier triggered roller balls were reported at all locations.
