MODERATE avalanche danger exists today on slopes steeper than 35 degrees in both above and below treeline on NW-N-NE-E-SE aspects with pockets of MODERATE danger on the S aspects. Lingering wind slabs in isolated areas and heavy snow loads sitting on top of weak persistent deep slabs will allow large destructive human triggered avalanches to remain possible. Even though these avalanches have become less likely, the consequences of such a slide would be very high.

We have started to collect data and will be sharing all of the information we gather on our observations page and in intermittent updates to this page. We plan to resume daily avalanche advisories in November as conditions dictate.

Early season conditions update #1

We are just beginning to collect field data on current snowpack and avalanche conditions. At this time we do not have sufficient information to issue avalanche advisories, but we are working to share the information that we do know. Daily avalanche advisories are planned to resume in November as conditions dictate. Intermittent early season updates to this page will occur earlier as conditions warrant.

Fall Avalanche Statement 

Daily avalanche advisories are planned to resume in mid November or later as conditions dictate. Occasional intermittent early season updates to this page may occur earlier if conditions warrant and resources are available.

We have stopped issuing daily avalanche advisories until the fall of 2012. The avalanche danger can and will change quickly this spring. Continue to monitor changing conditions and use caution when traveling in the backcountry. For general spring avalanche information read the full spring avalanche statement.

Early this morning, avalanche danger is LOW for all elevations and aspects. Widespread MODERATE avalanche danger will form today at all elevations and on all aspects in response to daytime warming. The vast majority of any avalanche activity that occurs today is expected to be human triggered. An isolated natural avalanche occurrence is unlikely, but not outside the realm of possibility during the late afternoon hours.

This morning, MODERATE avalanche danger exists near and above treeline in recently wind loaded areas on NW-N-NE-E aspects on slopes 35 degrees and steeper. A transition will occur during the late morning and afternoon hours to warming and wet snow instability. Pockets of CONSIDERABLE avalanche danger are expected to form at all elevations on all aspects on slopes 35 degrees and steeper by this afternoon.

Widespread MODERATE avalanche danger exists on all aspects at all elevations on slopes 32 degrees and steeper due to wet snow instability formed by rain on snow. The vast majority of avalanche activity today is expected to be human triggered, but an isolated natural avalanche is not impossible.

Widespread MODERATE avalanche danger will form on all aspects at all elevations on slopes 30 degrees and steeper due to daytime warming and rain on the snowpack today. If more rain impacts the area than forecasted, the danger of wet avalanches will increase.

Widespread MODERATE avalanche danger will form quickly today on all aspects at all elevations on slopes 30 degrees and steeper in response to daytime warming. Pockets of CONSIDERABLE danger may form this afternoon on slopes 35 degrees and steeper. The majority of instability that occurs today is likely to be human triggered, but natural avalanches are possible in isolated areas.

Widespread MODERATE avalanche danger will form quickly today on all aspects at all elevations on slopes 35 degrees and steeper in response to daytime warming. Pockets of CONSIDERABLE danger may form this afternoon on slopes 37 degrees and steeper. The majority of instability that occurs today is likely to be human triggered, but natural avalanches are possible in isolated areas.

Both above and below treeline widespread MODERATE avalanche danger will form on E-SE-S-SW-W aspects on slopes 35 degrees and steeper in response to daytime warming. On NW-N-NE aspects, avalanche danger is LOW with pockets of MODERATE danger in wind loaded areas both above and below treeline on slopes 35 degrees and steeper. Areas of unstable snow will exist within surrounding areas of seemingly stable snow.

On slopes steeper than 35 degrees near and above treeline, CONSIDERABLE avalanche danger will exist on N-NE-E aspects with pockets of CONSIDERABLE danger on the NW and SE aspects due to new snow and wind loading. Pockets of CONSIDERABLE danger may also exist on below treeline NW-N-NE-E-SE aspects on slopes steeper than 35 degrees. Human triggered avalanches are likely today, and natural avalanche are possible.
