In sintesi

Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

Avoid steep, rocky, and wind affected areas where triggering slabs is more likely.

    15 to 20 cm of new snow and extreme southwest winds formed wind slabs on lee aspects at upper elevations. These slabs are most likely to be reactive on steep slopes below ridgetops.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

On Tuesday, numerous skier triggered size 1 wet loose avalanches were reported on sunny aspects below treeline.

Last week's rain and warm temperatures triggered a widespread natural slab avalanche cycle up to size 3.

If you are heading into the backcountry, please consider sharing conditions via the MIN.

Snowpack Summary

15 to 20 cm of new snow and extreme southwest winds formed wind slabs on lee aspects at upper elevations. These slabs are most likely to be reactive on steep slopes below ridgetops. The new snow sits on a thick crust.

The snowpack below is moist to ground, and well consolidated in most locations. The snowpack depth tapers rapidly at lower elevations.

Weather Summary

Wednesday Night
Mostly cloudy. 0 to 5 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Thursday
Mostly cloudy. 40 km/h west ridgetop wind. Treeline temperature -9 °C.

Friday
Sunny. 50 km/h west ridgetop wind. Treeline temperature -7 °C.

Saturday
Sunny. 50 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level 1900 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
