Snowpack Summary

Low density snow will accumulate on Monday as dropping temperatures will also bring snow to lower elevations. Saturday night saw 5 cm of new snow in the Howe Sound area and 15-25 cm towards the eastern parts of the region. With a total of 30-50 cm of recent storm snow, fresh storm slabs will continue to form in the alpine and at treeline. Total snowpack depths are around 160 cm at treeline and over 2 metres at higher elevations, with the mid-pack rapidly gaining strength.

Problems

Storm Slabs

New snow will create fresh storm slabs at higher elevations. Storm slabs are expected to be thickest and most reactive in steep wind-exposed terrain.

Be cautious as you transition into wind affected terrain.Be alert to conditions that change with elevation.Avoid steep, open slopes.
