    The coastal storm should still deliver enough new snow to the alpine to form touchy new storm slabs up high. Strong winds are likely to build deeper, more sensitive slabs in the lee of wind-exposed features.

    Rainfall is expected to weaken surface snow and promote active loose wet avalanche conditions on Monday.

Avalanche Summary

No recent avalanches observed.Please submit any observations you have to the Mountain Information Network here.

Snowpack Summary

Snow depths are around 50 to 80 cm at treeline and alpine elevations, although there may be deeper deposits in wind-loaded areas. Approximately 30 cm of recent snow sits above a layer of surface hoar (north aspects) or a crust (south aspects). All but the highest elevation and/or smoothest slopes have insufficient snow cover for avalanches to occur at this time.
