Avalanche Summary
A Special Avalanche Advisory is in effect from 4:30 PM Wednesday until 4:30 PM Sunday. Avalanche conditions are more dangerous than we’ve experienced this season. You can easily trigger dangerous avalanches large enough to injure or kill you. Avoid traveling on and under slopes with a slope angle steeper than about 30 degrees. You can trigger avalanches from a distance or from below.
This week's storm built slabs of dense snow one to two feet thick on a widespread layer of weak snow on many west through north-to-east-facing slopes. This new avalanche concern is difficult to manage and requires conservative decisions and wide safety margins. Lower-angle southerly-facing slopes are the best options to help avoid being caught in an avalanche.
