The freezing level should rise to 1700 meters (might stay at 1500, fingers crossed) today dropping back down to surface on Wednesday, a weak trough pushes through Wednesday with mostly cloudy skies, some ridging for Thursday with another frontal band arriving Thursday night into Friday. Long term, looking like it may dry out for the weekend with cold arctic air moving in from the Northeast. Guesstimates: 25-40 cm by Wednesday morning, Trace-2 cm by Thursday morning, trace-1 cm by Friday morning, 15-20 cm by Saturday morning.

From Mitch Sulkers:
January 5, 2020
Variability continues to be the name of the game in the Whistler area. Snow depths vary from 150-300cm depending on aspect at 2100m.
Winds in the alpine and ridgetops have remained at extreme for over 35 straight hours as of this morning, with northern exposures below ridgecrests heavily loaded.
There are at least five layers of concern in the snowpack, with the 191123 facet/crust combo being the deepest. A primary concern is that any one of the suspect layers triggered closer to the surface could trigger this deeper instability.
At surface, stormslabs and windslabs can be found in any areas that are wind-affected, including open areas below treeline. Cornices are also growing and may be triggered remotely.
Skied NW, W, and SW aspects from 2100-1760m today. Tight trees skied the best, with loose dry sluffs occuring even on some lower 30 degree slopes.
Trailbreaking was reasonable, with ski penetration from 25-50cm, depending on aspect and elevation.
With all the variability and lack of observations, it's worth being very careful in one's approach to even simple avalance terrain.
