Lo esencial

Continue to assess your local conditions. Large cornices and pockets of wind slab may persist along ridgetops in the alpine.

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

A variety of snow surfaces exist at higher elevations, including firm wind affected surfaces, hard crusts and loose powder snow (primarily in sheltered north facing terrain).

Large, fragile cornices can be found on exposed ridgelines and should be given a wide berth.

Below roughly 1300 m anticipate a widespread, supportive crust to deteriorate through the day with warming and solar effect.

Weather Summary

Tuesday Night

Mostly clear. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -6 °C.

Wednesday

Sunny. 10 to 20 km/h west ridgetop wind. Treeline temperature -6 °C.

Thursday

Mix of sun and cloud. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Friday

Cloudy with 2 to 10 cm of snow. 30 to 50 km/h south ridgetop wind. Treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
