Kernpunkte

Avalanche danger should remain LOW for all elevations and aspects again today. While avalanches are unlikely, a few scattered loose wet avalanches are not impossible on some isolated terrain features. Use normal caution when traveling in the backcountry.

    Another refreeze should have occurred last night since the clear skies allowed the snowpack to radiate heat out into the night. While slightly cooler temperatures and light to moderate winds should help keep the snow surface from melting too quickly, today's sunny skies and warm temperatures will still cause wet snow to form by mid-morning. Despite the wet snow formation, wet snow instabilities should remain limited since the snowpack has already been through so many melt freeze cycles and the sun still remains relatively low in the sky. If any wet snow instabilities do occur today, human triggered roller balls and pinwheels should represent the majority of them. Actual loose wet avalanches are unlikely but not impossible. The sun-exposed E-SE-S-SW-W aspects will represent the best places to find wet snow instabilities today.

Avalanche Discussion

The wind scoured SW-W aspects of Castle Peak held 2-4 inches of soft corn snow above a supportable base by 2:30 pm yesterday. Some minor softening also occurred on the NW aspects. Ski cuts and general observations on these aspects did not reveal significant signs of wet snow instabilities. On more northerly aspects of Castle Peak, the snow surface was a mix of firm melt freeze crusts and soft wet snow. Snowpit data on a NNW aspect at 8500 ft. showed a well bonded and strong snowpack consisting of the softer surface snow above a thick rain crust with wet snow below that.
