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.
The most dangerous slopes are north through east to south slopes were strong winds continue to drift snow into stiffer slabs. On northerly and easterly aspects there is an abundance of weak snow close to the ground and avalanches could step down to this layer creating a large slide.
