Avalanche Summary

No significant avalanche activity has been reported in recent days, aside from small wet loose avalanches during warm, sunny weather.

Snowpack Summary

A cooling trend will create hard, crusty surfaces, though it's uncertain if Friday night will bring a full refreeze. Light rain transitioning to snow may produce dust-on-crust conditions by Saturday afternoon. The snowpack is strong and well bonded, and continues to melt rapidly at lower elevations.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Be alert to conditions that change with elevation and sun exposure.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
