Avalanche Summary

No recent avalanches have been reported in the region, but we expect wet loose avalanches to occur over the next few days as skies clear and the freezing level rises to mountain tops.

Snowpack Summary

Expect surfaces to melt and weaken as the freezing level climbs to 2700 m on Saturday. This will occur rapidly on sun-exposed slopes.

The upper snowpack consists of various melt-freeze layers and the lower snowpack is strong and bonded.

Terrain and Travel Advice

  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • Minimize your exposure time below cornices.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
