    Watch your overhead exposure during the heat of the day - Cornices and loose wet avalanches may be easy to trigger when the sun is strong.

Confidence

Moderate

Avalanche Summary

Small wet loose avalanches (size 1 to 1.5) have been reported the past few days, especially on sun-exposed slopes. Small wind slabs may have occurred during stormy weather on Wednesday.

Field observations are currently very limited in this region. Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

5 to 15 cm of recent snow sits above crusts and hard snow. Isolated wind slabs may exist in steep alpine terrain. Melt-freeze crusts near the surface exist to mountaintops on sun-exposed slopes.

Surfaces will transition to wet snow with daytime warming and generally refreeze at night.

Cornices are large and may become weak with daytime warming.

Terrain and Travel Advice

  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Be alert to conditions that change with aspect and elevation.
