    Strong southwest wind has blown recent snow into lee terrain features, forming wind slabs. Use added caution above the rain-snow line, where these deposits may be reactive to human traffic.

Avalanche Summary

Small storm slab avalanches were triggered by skiers and naturally on Wednesday. They were 10 cm thick and generally on northerly aspects. The likelihood of triggering avalanches will increase above the snow-rain line due to continuous snowfall this weekend.
