Highlights

Triggering an avalanche 2-5 feet deep on buried weak layers is possible in very steep terrain (>35°). Evaluate very steep slopes carefully, especially on the north half of the compass where slopes were previously loaded by the wind.

    Weak layers of faceted snow exist in the middle of the snowpack and near the ground on most slopes. Avalanches involving these layers will be 2-3 feet deep and up to 5 feet deep on heavily wind-affected slopes. Triggering one of these dangerous avalanches is possible on very steep slopes over 35 degrees. Signs of instability such as cracking, collapsing, or recent avalanches will likely not be present before triggering a large avalanche capable of propagating long distances. You're most likely to trigger an avalanche where the snowpack is thin - very steep, rocky, convex terrain should remain suspect. Multiple tracks on a slope do not indicate stability with this problem type. 

Avalanche Discussion

Today, conditions continue to transition from several days of warm weather to colder temperatures and cloudier skies. Yesterday, partly cloudy skies allowed for the sun to warm the snow surface. A refreeze last night will have solidified the surface, likely creating a supportable snowpack. The snowpack will continue to stabilize as temperatures cool off, but with clearer skies today, here are a few things to keep in mind. 

  • Wet loose avalanche activity could still be a concern with enough heating today. Look for softening snow surfaces and rollerballs coming from your sled or skis. If you see these signs or find the snowpack becoming unsupportable, move to lower-angle slopes.
  • Large cornices are most likely still sensitive right now after the last few days of sun. Minimize time spent on slopes with large cornices looming overhead. They can break unexpectedly and act as very large triggers.

Several bear sightings have been reported this spring. When planning for the day, bear spray, group travel, and appropriate food storage should be considered.
