High pressure in a Northerly flow aloft will bring cold temperatures and clear skies for today. This trend will continue into Friday, and hopefully the high will begin shifting East by Friday night allowing a front onshore for Saturday/Sunday. In the mean time enjoy the sun! Awesome turns to be had above 1800 meters.

From South Coast Touring:

Mitch Sulkers:
Observations from the past three days in the Whistler backcountry. Snow accumulations from 60-265cm encountered between 1900m and 2200m, depending upon aspect and elevation. Above 1950m on north aspects, rounding facets are the predominant basal layer, from 20-30cm deep. Where the snowpack is deepest (generally higher and on more northerly aspects) this rounding process is progressing well; in shallow regions, the facets tend to be less consolidated and may well be "fist" resistance (and hence a poor foundation). In areas from 1900 to 1970m, these facets are overlain with a fairly substantial melt-freeze crust from 181103. Few significant tests in recent stability evaluations, but expect variability again based on aspect, slope angle, and elevation. We occasionally got hard compression results, sudden planar, down as far as 90cm from the surface in deeper, higher elevation regions. Skiing remains very good in supported, higher terrain, with 20-30cm of near surface facets skiing very well. Be cautious in areas of irregular ground surface or small bushes, as these areas may have voids capable of swallowing a ski as one glides along...
