In sintesi

Snow continues to accumulate at higher elevations, increasing avalanche danger. Assess for new slabs in steep terrain.

    Stormy weather may build new slabs at higher elevations. They may not bond well with old snow surfaces, particularly where the new snow rests on a hard crust. Assess for slab conditions and the bond with the old surface as you travel.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

We haven't received any reports of recent avalanche activity.

Looking forward, riders could trigger storm slabs at higher elevations, particularly if they don't bond well to underlying old surfaces. Assess for slab formation and reactivity before jumping into high-consequence terrain.

Please consider submitting a MIN to let us know what you're seeing out there.

Snowpack Summary

Around 10 to 30 cm of snow from Tuesday to Wednesday morning sits on moist snow or a hard melt-freeze crust. More snow will accumulate over the day on Wednesday, adding to these snow amounts. The snow is also falling with strong wind, forming deeper deposits in lee terrain features. Below 1500 m, all this precipitation is falling as rain, wetting an already wet and melting snowpack.

The remainder of the snowpack is strong.

Weather Summary

Tuesday Night
Cloudy. 10 to 20 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1500 m.

Wednesday
Mostly cloudy. 5 to 15 cm of snow and local amounts up to 25 cm possible. 30 km/h west ridgetop wind. Treeline temperature -4 °C. Freezing level 1600 m.

Thursday
Mostly cloudy. 5 to 10 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -6 °C.

Friday
Mix of sun and clouds with isolated flurries. 1 to 2 cm of snow. 20 km/h northwest ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Carefully evaluate steep lines for wind slabs.
  • Make observations and continually assess conditions as you travel.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
