Points saillants

A supportive surface crust makes for generally safe avalanche conditions. Consider scaling back your terrain choice if snow surfaces begin to weaken or moisten from daytime warming.

    Wet loose avalanche likelihood may increase throughout the day with daytime warming and sunny conditions, particularly on steep south-facing terrain.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

As temperatures gradually decline expect to find a widespread crust on the surface. Anticipate the surface snow to weaken throughout the day with daytime warming and potential sun effect.

80 to 120 cm below the snow surface, a weak layer of faceted snow may exist sitting atop a crust on all but high north aspects.

The mid and lower snowpack is generally settled and strong.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • The more the snowpack warms-up and weakens, the more conservative you`ll want to be with your terrain selection.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
