Widespread areas of CONSIDERABLE avalanche danger exist near and above treeline on NW-N-NE-E-SE aspects 30 degrees and steeper due to newly formed wind slabs and below treeline on NW-N-NE aspects 30 degrees and steeper due to persistent slabs. Natural avalanches are possible, human triggered avalanches are likely today. Significant avalanche danger exists below treeline. --- Everyone is chomping at the bit to get out there today. Only a small percentage have a handle on the weakness of the existing snowpack and the reality of avalanches today. Conservative terrain selection and effective group communication are imperative.

Fall storms are starting to impact the forecast area with rain and high elevation snow returning to the Sierra. The operational portion of the avalanche center has yet to brush off the dust accumulated during the summer hiatus. As mid/late October approaches, work will resume to get the operational program ready to issue regular avalanche advisories once conditions warrant.

The non-profit fundraising portion of the avalanche center has been hard at work organizing fall events. Take a look at the SAC calendar for upcoming events to fuel your excitement.

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.

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.

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.

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.

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.

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.

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.

Near and above treeline, pockets of MODERATE avalanche danger exist on SE-S-SW-W-NW aspects on slopes 35 degrees and steeper. Expect to find small wind slabs in a variety of lee areas near ridgelines. For below treeline areas, avalanche danger remains LOW.

In most areas the avalanche danger is LOW. On a few isolated slopes steeper than 35 degrees, small pockets of MODERATE avalanche danger may remain on near and above treeline aspects along the Sierra Crest due wind slabs resting on frozen crusts. Small loose snow avalanches may also be possible on some steep slopes at all elevations today due unconsolidated snow resting on those frozen crusts.

On slopes steeper than 35 degrees, isolated pockets of MODERATE avalanche danger may remain on near and above treeline aspects along the Sierra Crest due wind slabs resting on frozen crusts. Small loose snow avalanches may also be possible on some steep slopes at all elevations today due unconsolidated snow resting on those frozen crusts.

On slopes steeper than 35 degrees, isolated pockets of MODERATE avalanche danger may exist on near and above treeline aspects due new wind slabs resting on frozen crusts. Small loose dry snow avalanches may also be possible on some steep slopes at all elevations today due new snow resting on frozen crusts.
