Avalanche danger starting at LOW danger early this morning will steadily increase as the day progresses. Avalanche danger is expected to become CONSIDERABLE this afternoon near and above treeline on NW-N-NE-E-SE aspects on slopes 35 degrees and steeper. Below treeline, avalanche danger will increase to MODERATE danger with pockets of CONSIDERABLE danger on NW-N-NE aspects on slopes 35 degrees and steeper.

MODERATE avalanche danger exists on all aspects on slopes 35 degrees and steeper due to a combination of strong shifting winds, new snow, and new as well as old weak layers. Human triggered avalanche will remain possible today. The largest and most fragile snow will exist on wind loaded near and above treeline slopes along the Sierra Crest. Most other avalanche activity shoud remain small due to the limited accumulation amounts.

In near and above treeline terrain, MODERATE avalanche danger exists on all aspects on slopes 35 degrees and steeper where wind slabs rest on weak snow. Human triggered avalanches will remain possible today in these areas. Below treeline the avalanche danger has decreased to LOW even though some small loose snow instabilities do remain possible.

In near and above treeline terrain, some pockets of MODERATE avalanche danger may still linger on all aspects on slopes 35 degrees and steeper where wind slabs rest on weak snow. Human triggered avalanches will remain possible today in these areas. Below treeline the avalanche danger remains LOW even though some small loose snow instabilities may still continue.

Near and above treeline, avalanche danger is MODERATE on NW-N-NE-E-SE-S aspects on slopes 35 degrees and steeper due to a new round of wind slab formation that occurred last night. For all other areas, avalanche danger is LOW. The greatest areas of instability are expected near and along the Sierra Crest.

On a regional scale the avalanche danger remains LOW for most elevations and aspects. Very isolated and sporadic pockets of MODERATE danger may exist in complex or extreme near and above treeline terrain where isolated unstable wind slabs rest on layers of weak snow. Continue to use normal caution when traveling in the backcountry.

On a regional scale the avalanche danger remains LOW for all elevations and aspects. While finding a small isolated unstable wind slab is unlikely, it is not impossible today in a few scattered places in near treeline or above treeline terrain. Continue to use normal caution when traveling in the backcountry.

Near and above treeline, areas of MODERATE avalanche danger will develop this morning as new wind slabs form on the most heavily wind loaded NW-N-NE-E-SE aspects on slopes 35 degrees and steeper. For all other areas, avalanche danger remains LOW. In low elevation areas where rain continues to fall today, isolated loose wet snow avalanches are possible on slopes 37 degrees and steeper.
