    The upper snowpack continues to adjust to the recent spring-like weather. Expect small loose wet avalanches to be reactive on steep, solar aspects with sun and warm temperatures on Tuesday.

Terrain and Travel Advice

  • As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Snowpack Summary

Warm temperatures and solar radiation continue to produce moist snow surfaces on all but high-elevation northerly terrain. As temperatures drop overnight a surface crust will form.

The mid and lower snowpack is generally well-settled and bonded.
