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.

    Likelihood
    Possible - Likely
    Size
    1–1.5
    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.

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.

Confidence

Moderate - Due to the number of field observations
