Shady, sheltered slopes may still provide good riding.

    Watch for surface snow becoming moist on sunny slopes. Rollerballing and pinwheeling are indications that the snow is primed for wet loose avalanches.

On Sunday, riders on a south slope in the alpine triggered a wind slab avalanche (photo below).

The surface snow on sunny slopes may produce small wet loose avalanches with temperatures above 0°C.

If you venture into the backcountry, please consider submitting your observations to the MIN.

Terrain and Travel Advice

  • The snowpack is generally stable; it may be appropriate to step out into more complex terrain.
  • Make observations and continually assess conditions as you travel.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
