    As the surface snow becomes wet and saturated with heavy rainfall, wet loose avalanches will be likely.

Moderate

Avalanche Summary

No recent avalanches have been reported, but observations are very limited in this region.

If you're heading out into the backcountry, please consider sharing your observations on the MIN.

Snowpack Summary

Up to 10 cm of new snow can be found at upper elevations, which was redistributed by strong southerly winds into greater accumulations on lee slopes. This builds upon previous storm slabs, which currently overlie older layers and a thick melt-freeze crust down 50 to 60 cm.

At treeline, a crust is supportive to skis with moist/wet snow underneath. The new snow seems to be bonding well to the surface crust. At lower elevations, the crust is variably breakable.

Total snowpack depths range from around 80 to 150 cm deep at treeline, and diminish rapidly at lower elevations.

Terrain and Travel Advice

  • Avalanche danger is expected to increase throughout the day.
  • Keep in mind that the high density of wet avalanches can make them destructive.
  • Be alert to conditions that change with aspect and elevation.
