FORECAST:
Ridge of high pressure will bring a mix of sun and cloud in a Northerly flow aloft this morning. Cloudy skies can be expected later this am as the ridge slowly moves South and the low sends cloud our way. The FL will spike at around 1000 meters dropping back down to surface tonight. Weak frontal band arrives around midnight with light precip into Wednesday morning. Around noon the precip will diminish with cloudy weather, with a chance of a brief break in the afternoon. Ridge rebuilds for Thursday with a mix of sun and cloud. Ridge brings sunny weather into Saturday. Next snow will happen on Sunday. Guesstimates: 8-12 cm by Wednesday am, 0 cm Thursday--Sunday. Possibly 15-20 cm by Monday.

Avalanche Summary
Avalanche reports during Sunday's storm were limited to a few small (size 1) storm slab avalanches, primarily on wind affected slopes.
Snowpack Summary
Recent snow is settling but may still be blown around in open terrain by westerly wind. Stormy weather since Thursday has delivered about 30 cm of snow to the Whistler area and closer to 50 cm further west and south. This snow sits above a widespread crust, with the exception of high north-facing terrain. Observations suggest the snow has bonded well to these old interfaces. There are currently no concerning weak layers in the snowpack, although a spotty early season facet layer deep in the snowpack could return as a problem later in the season.
Remember that cornices along ridgelines are large at this time of year and always have the possibility of failing naturally or from the weight of a human.
