In sintesi

Low avalanche danger exists at all elevations throughout the forecast area.  Loose wet avalanche activity should remain limited today.  If we receive more rain or more intense sun than forecasted, loose wet avalanches could become possible.  Avoid travel in areas below large cornices and glide cracks.

    Slightly colder overnight temperatures with increasing cloud cover and winds should all help to make loose wet avalanche activity unlikely today.  Any loose wet activity that does form should remain small.  If we receive more rain or longer periods of intense sun than forecasted, loose wet activity could become possible especially on E-SE-S-SW-W aspects.

    If the snow becomes wet and unsupportable in your area, it's time to change aspects to where colder snow exists.  Terrain traps, such as gullies, can magnify the consequences of even small loose wet activity.  Areas below cornices and glide cracks should be avoided. 

Avalanche Discussion

Observations were made and received yesterday from Red Lake Peak (Carson Pass area), Relay Peak (Mt. Rose area), and Negro Canyon (Donner Summit area).  Cloud cover with light rain was reported in the Northern part of the forecast area while the southern part remained in partly cloudy conditions.  Supportable snow conditions were reported at the higher elevations of Relay Peak and Carson Pass while Negro Canyon had wet surface snow with boot pen of 6'' at 3pm near 7000'.  With mostly clear overnight skies, a 4'' melt freeze crust provided good corn snow conditions at Carson Pass.  No signs of loose wet avalanche activity was reported at any location.
