In sintesi

DANGEROUS AVALANCHE CONDITIONS WILL EXIST FOR THE NEXT SEVERAL DAYS.

The danger is estimated to be HIGH and may rise to EXTREME in some areas in the next day or two.

Long running natural and human triggered avalanches are expected. Even unusual avalanches are possible in atypical terrain on atypical aspects and elevations.

Travel Advice: Avoid being on or beneath steep slopes.

You can still trigger deep and destructive avalanches 3-5'+ deep and hundreds of feet wide.

Key Information: The most suspect terrain includes mid and upper elevation west to north to southeast facing slopes but I am worried with the recent and expected snowfall and wind that some southerly aspects and lower elevation northerly aspects will also become active. I am uncertain of timing. It may be today, tomorrow, or Tuesday.

These types of avalanches are most pronounced in steep, thin rocky terrain...and areas that have previously avalanched this winter.

Keep in mind:

Existing tracks on the slope offer zero signs of stability.

Avalanches can be triggered from a distance or below.

Any fresh wind slab or new snow avalanche may step down several feet into older snow..

New snow avalanches are possible on all aspects and elevations and will likely get bigger and more active over the next few days. Extreme caution is required.

Lastly, pay attention to cornices. Cornices are developing along many ridgelines and we have seen a few avalanches triggered from cornice falls. Be sure to give cornices a wide berth as they typically break much further back than expected and could trigger a much larger avalanche below.

Recent Activity

Avalanches ran with explosive control work yesterday. Natural avalanching is also suspected in the steepest terrain.

Our Week in Review - where we highlight significant avalanche and snow events for the past week - is published.

Snow and Weather

Skies are overcast with a trace of new overnight.

Mountain temperatures are in the single digits to mid-teens.

Winds are generally light from the north; however the highest elevations are seeing gusts to 35.

Storm totals since Thursday night are now up to 15-20" with snow water equivalents pushing 2.0".

We're not done. The next storm is on tap for tomorrow.

We'll see mostly cloudy skies today with temps in the teens. Northwest winds should increase to 20-25mph along the highest elevations.

The next storm arrives tomorrow and will be accompanied by strong northwest winds and the arrival of snowfall on a warming trend. Another 8-14"+ can be expected through Wednesday.

Special Announcement

The final report about the Wilson Glade avalanche in Millcreek Canyon has been published. Our deepest condolences go out to the friends and families involved in this tragic accident.
