Regions: Sea To Sky.

Does green mean go? No! Keep your wits about you: avalanches are still possible in isolated areas.

Confidence

Fair - Timing or intensity of solar radiation is uncertain

Weather Forecast

Any lingering precipitation should peter out by Saturday, leading into a dry week. Temperatures warm on Sunday, when the freezing level is forecast to spike up to 2800 m. Winds are light to moderate from the north.

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

Cornices are reported to be large and potentially fragile. On high north-facing terrain light amounts of cold, lower density snow overlie a widespread thick hard crust. Below about 2000 m, there is no snow on the crust and surface runnels show the effect of recent rain. Sun-exposed slopes recently became moist, or wet with daytime warming and solar radiation and are also likely now refrozen. Below the surface crust, the snow may still be moist; however, the mid and lower snowpack are generally strong and well-consolidated. Most of the terrain below treeline is below threshold for avalanche activity.

Avalanche Problems

Cornices

Large and fragile cornices may collapse. Isolated areas of wind slab may also be found.
Avoid steep slopes below cornices.>Be cautious as you transition into wind affected terrain.>

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 3 - 5
