Points saillants

We are in Spring Conditions. Avalanches are still possible.

Up to 25 cm of storm snow will see increasing solar radiation and decreasing cloud cover. Look out for signs of solar warming and wet loose activity as the forecast period progresses.

    A warming trend with decreasing cloud cover will make this problem more prevalent as the forecast period progresses.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
