Points saillants

Periods of low hazard are the best time to consider exploring more complex terrain.

Riding conditions will improve once the surface crust has softened on sun-affected slopes.

    Watch for surface snow becoming wet and heavy as warm temperatures and sun break down the crust.

Avalanche Summary

Small loose wet avalanches and pinwheeling have been observed from steep, sun-affected slopes. With the current weather forecast, we expect small loose wet avalanches will remain possible to trigger on Wednesday.

If you are headed into the backcountry please consider submitting a MIN report.

Snowpack Summary

Strong sunshine and warm temperatures have formed a crust on most surfaces, except on north-facing alpine slopes where the snow may remain loose and dry. With daytime warming, the crust will likely soften and melt, improving riding conditions that have been reported as challenging in some areas. However, loose wet avalanches may also become possible during this time. The mid and lower snowpack is dense, well-settled, and currently shows nothing concerning.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.
