The freezing level was likely low enough on Thursday for new snow to accumulate in alpine terrain, forming wind slabs along ridgelines and open alpine slopes.
Avalanches are possible on wind-loaded features in the alpine.
The freezing level was likely low enough on Thursday for new snow to accumulate in alpine terrain, forming wind slabs along ridgelines and open alpine slopes.
While direct observations are lacking, recent storms likely produced some wind slab and wet loose activity. As temperatures cool on Friday, wind slabs at upper elevations will be the main concern.
A few small (size 1) skier-triggered slabs were reported on Mount Seymour on Tuesday.
10 to 20 cm of wind-affected snow is possible at upper elevations, while treeline elevations have a settled, rain-soaked snowpack. Lower elevations are melting out rapidly.
