Kernpunkte

Wet loose avalanches are possible on steep sun-exposed slopes. Give cornices a wide berth from above and below.

Where a thick surface crust exists avalanche activity will be unlikely.

    Daytime warming and sunshine may affect the snowpack. Moist snow surfaces, snowballing and wet loose avalanches are indicators of a weakening snowpack.

Avalanche Summary

No recent avalanche reports by 4 pm on Wednesday. Sunshine and rising temperatures may weaken the surface snow and initiate small wet loose avalanches on southerly-facing slopes. Use caution on north-facing slopes in the alpine as they may host pockets of wind slab.

If you head into the backcountry, please submit any observations or photos to the Mountain Information Network, observations are limited in the spring.

Snowpack Summary

A widespread surface crust likely exists at all elevations, except on high north-facing slopes where pockets of wind affected dry snow exist above 2000 m. Watch for moist, unstable snow on southerly slopes with sun and warm temperatures.

Below treeline elevations have minimal snow cover if any at all. Expect challenging travel conditions with hazards like rocks, stumps and open creeks.

Terrain and Travel Advice

  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
