WEDNESDAY: Broken cloud cover, freezing level holding around 1500 m, light gusting moderate southwest wind, trace of precipitation possible.THURSDAY: Scattered cloud cover, freezing level around 1200 m, light northerly wind, no significant precipitation expected.FRIDAY: Scattered cloud cover, freezing level around 900 m, light variable wind, no significant precipitation expected.

Snowpack Summary
Monday's storm produced over 200 mm of precipitation that mostly fell as rain. Winds were extreme out of the south/southwest. Cornices likely formed on many ridgelines. Terrain above 1300 m will likely receive 20 to 30 cm of snow Tuesday night which is expected to form fresh storm slabs. Alpine areas near Squamish have the most snow, with around 70 cm of settled snow on the ground. In the alpine, there may be a crust lower in the snowpack. It is thought that there is insufficient snow for avalanches below 1500 m.
