If the sun comes out, expect wet loose avalanches to start.

Avoid being exposed to steep slopes in the sun.

Avalanche Summary

No new avalanches were reported on Sunday at the time of publishing.

Several small dry loose avalanches were reported on Saturday.

Snowpack Summary

20 to 40 cm of snow accumulated above around 1000 m to 1500 m over the past few days. All this snow sits on surface hoar crystals that overly faceted or wind-affected snow on northerly alpine terrain or a hard melt-freeze crust elsewhere.

A widespread crust that formed in early February is buried anywhere from 80 to 150 cm deep. This crust has a weak layer of faceted grains above it that are slowly strengthening. This layer is currently dormant.

The remainder of the snowpack is settled.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Avoid exposure to steep sun exposed slopes.
  • Carefully evaluate steep lines for wind slabs.
  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.

Problems

Loose Wet

If the sun is out, wet loose activity is likely.

Aspects: East, South East, South, South West, West.

Elevations: All elevations.

Likelihood

Possible

Expected Size

1 - 1.5

Storm Slabs

An icon showing Storm Slabs

Recently formed storm slabs may not bond well to underlying layers, including weak surface hoar or facets on northerly terrain, or a hard melt-freeze crust elsewhere. Deeper deposits may be found in lee terrain features near ridges.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 2
