    Be proactive and assess the snowpack, as observations are very limited this time of year. Testing a small slope that's similar to a larger slope you want to ride is a good place to start.

    Small wet loose avalanches may be possible on steep slopes, sheltered from the wind.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

Avalanche Summary

Please consider sharing any observations you have on the Mountain Information Network.

Snowpack Summary

A melt-freeze crust is expected on all slopes that saw the sun on Sunday and low-elevation shaded slopes.

In sheltered spots at treeline, 5 to 10 cm of snow may be sitting on large surface hoar crystals.

The most prominent of several melt-freeze crusts in the lower snowpack is 100 - 120 cm deep and decomposing.

Snowpack depth is around 100 to 140 cm at treeline and decreases rapidly below about 1500 m.
