Early Season Conditions Update #1

Our first series of winter storms for the season are approaching our region today through Saturday.  In areas that receive the most snowfall, isolated wind slabs and minor loose wet avalanches could become possible.  Practice safe travel protocols when in or near avalanche terrain.  Daily avalanche advisories will begin as the snowpack builds.

    Wind slabs could become possible in the heaviest wind drifted areas in near treeline and above treeline terrain mainly above 8000'.  Strong to gale force S/SW winds are forecasted throughout the incoming storms.  In areas that receive the most snow, wind slabs could form on NW-N-NE-E-SE aspects.  Look for areas of blowing snow, cornice formation, and wind pillows.

    As snow levels fluctuate and rise throughout these incoming storms, small loose wet avalanches could become possible due to rain on new snow.  These loose wet avalanches are expected to be in isolated areas that receive the most snow and be small in size. 

Avalanche Discussion

The observations page is available for sharing snowpack and avalanche observations submitted to the avalanche center.  Let us know what you see out there!

Excitement is high with the approaching storm and the kick off of our winter season.  Even after this series of storms, our snowpack will be shallow with a minimal amount of useable snow for recreation in most areas.  Many hazards and obstacles will exist throughout the region including: exposed trees, rocks, bushes, open water, creek crossings, etc.  Use caution during this early season to avoid injury.

This is the time to get all of your backcountry gear out and in good working condition.  Get out with your friends and partners in the new snow to practice avalanche rescue so you will be prepared for the coming winter.
