Highlights

Spring like weather may break down the surface snow, creating the possibility of small wet loose avalanches in steep terrain features.

    Wet avalanches will be most likely where warm temperatures are combined with sun on south facing slopes. Buried crusts will create ideal sliding surfaces for avalanche activity.

Avalanche Summary

No recent avalanches have been reported in this region. Small wet avalanches may be possible to be triggered by riders on steep slopes as the warming affects the snowpack.

If you do head into the backcountry please submit any observations and or photos on the Mountain Information Network.

Snowpack Summary

A widespread melt freeze crust likely exists to mountain top. As the freezing level rises over the day, this may begin to soften and break down.

The mid and lower snowpack is made up of a series of crusts and rounded grains. The snowpack is generally well consolidated.

Overall, the snow depth remains shallow, creating challenging travel conditions and hiding early season hazards just below the snow surface.

Terrain and Travel Advice

  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
  • Avoid sun exposed slopes, especially if snow surface is moist or wet.
  • Be cautious of buried obstacles especially below treeline.
