Avalanche Summary

A Special Avalanche Advisory is in effect for the southern San Juan Mountains. New snow and winds through the holiday weekend will create dangerous avalanche conditions developing Saturday afternoon through Monday. Avalanche conditions will be more dangerous than we’ve experienced in weeks. Adjust your weekend plans accordingly, and check the forecast frequently for changing conditions.

New snow and wind continue to keep danger elevated at all elevations. Avalanches will be larger where thick slabs of stiff snow sit above weak buried layers. Move to low-angle terrain without steep slopes overhead if you observe fresh avalanches, shooting cracks, or collapses in the new snow.
