Avalanche Summary
No avalanches have been reported in this region recently, but Monday's heavy snowfall will create large and touchy storm slabs.
Snowpack Summary
As of Monday afternoon, 30-45 cm of new snow has fallen in the South Coast mountains and is expected to continue into Monday evening. The new snow will form touchy storm slabs on Tuesday, especially at higher elevations and on wind loaded features. 30-50 cm of snow from last weekend's storm is rapidly settling, although a MIN report from Sunday suggests there were some instabilities in the old storm snow. Total snowpack depths are around 170 cm at treeline and over 2 metres at higher elevations, with the mid-pack rapidly gaining strength. Thanks to the riders in the Sky Pilot area for their recent MIN reports!
