    Wet loose avalanche activity is expected to increase under strong sunshine and high freezing levels. The greatest hazard will be on steep slopes where the snowpack has gone isothermal and wet sluffs may gouge deeply.

Avalanche Summary

No recent avalanche reports, but observations are very limited.

If you're heading into the backcountry, please share what you see on the Mountain Information Network.

Snowpack Summary

Some dry snow may still remain on shady northerly aspects in the high alpine.

A typical spring diurnal pattern is in effect: daytime warming melts the upper snowpack, while overnight cooling usually forms a crust at higher elevations. Freezing levels are expected to soar to 3000 m over the next couple of days, with very limited cooling and crust recovery overnight.

Lower elevations will not refreeze and are experiencing an all-melt, no freeze scenario, and are melting out quickly.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Use appropriate sluff management techniques.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Start your day early and be out of avalanche terrain during the heat of the day.
