As of 4:30 PM, there is a HIGH avalanche warning for the backcountry
   west of Rock Creek north to Sonora Pass. Heavy dense new snow is adding
   additional load and stress to a variable and unpredictable snowpack.
   Weak faceted snow at the base of the snowpack and above the ice lens
   from the end of January storm remain very active and skier triggered
   slides this afternoon failed on the ice lens, then collapsed on the
   depth hoar on the ground. Newly formed wind slabs also are loading the
   snowpack on northwest to northeast aspects. This HIGH avalanche rating
   applies to all slopes from 7,500 ft to the Sierra Crest. Stay on low
   angle terrain and avoid avalanche runout areas. Be cautious about
   terrain selection and are avoiding anything steeper than very low 30
   degree slope angle. Travel in avalanche terrain is not recommended.

   MOUNTAIN WEATHER

   As of 4:30 PM, the area from Rock Creek north to Sonora Pass is
   experiencing the first of two bursts of heavy precipitation. According
   to the National Weather Service, the second burst will occur Monday
   morning with another 1 inch of water being added to the snowpack.
   Around the Mammoth to June Mountain areas this storm could add 2 inches
   of water to the snowpack above 8,500 ft. Snow drifting into dense
   windslabs will continue to load all north aspects until late tomorrow.

   SNOWPACK AND AVALANCHE DISCUSSION

   BOTTOM LINE

   The avalanche danger rating is estimated to be HIGH. Heavy dense new
   snow is adding additional load and stress to a variable and
   unpredictable snowpack. Weak faceted snow at the base of the snowpack
   and above the January ice lens is actively producing avalanches this
   afternoon. Several skier triggered slides failed on the ice lens then
   collapsed on the faceted snow above the ground. Newly formed wind slabs
   are also a concern. The HIGH avalanche rating applies to all slopes
   from 7,500 ft to the Sierra Crest. Rain below 8,000 ft is loading
   shallow snowpacks on all aspects. Stay on low angle terrain and avoid
   avalanche runout areas. Travel in avalanche terrain is not recommended.

   Please note that the avalanche danger rating in this advisory expires
   in 24 hours. This advisory is the best interpretation of snow pack
   conditions and NWS forecasts issued today. Backcountry travelers should
   be aware that elevation and geographic distinctions are approximate and
   that a transition zone exists between upper and lower elevations.

   Avalanches do not happen by accident and most human involvement is a
   matter of choice not chance. Most avalanche accidents are caused by
   slab avalanches that are triggered by the victim of member of the
   victim's party. Even small slides can be dangerous. Always practice
   route finding skills and carry avalanche rescue gear. Remember that
   avalanche danger ratings are only general guidelines. Distinctions
   between geographic areas, elevations, slope aspects and slope angles
   should be made.
