Regions: South Coast.

What little snow there is in the region lies mainly in the alpine. Hardy travelers to these areas will need to manage small loose wet avalanche hazards on Wednesday.

Confidence

Moderate - Due to the number of field observations

Weather Forecast

Tuesday night: Clear. Light northeast winds. Freezing levels continuing to rise, topping out at about 2100 metres.Wednesday: Sunny. Light northeast winds. Alpine high temperatures around +1 with freezing levels remaining near 2000 metres.Thursday: Sunny. Light variable winds.

Avalanche Summary

No avalanches have been reported. Please submit any observations you have to the Mountain Information Network here.

Snowpack Summary

Alpine areas near Squamish have the most snow, with a suspected 70 cm of settled snow on the ground. In these areas there may be a crust lower in the snowpack, however it is now suspected to be well bonded to the overlying storm snow. There is generally insufficient snow for avalanches below 1500 m.

Avalanche Problems

Loose Wet

Warm temperatures and strong sunshine will destabillize surface snow and promote loose wet avalanche activity on sun-exposed slopes on Wednesday. Loose wet slides may occur naturally or with a human trigger.
Be aware that low-angle December sun tends to focus radiation on steeper slopes.Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

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

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 1.5
