Snowpack Summary
Recent storm accumulations have been variable throughout the region, however some ares saw significant snowfall earlier in the week. Recent accumulations may sit over a rain crust that extends up to 2000 m, the new snow may have a poor bond to this crust. Widespread wind slabs exist at higher elevations, although I suspect that in recent days they may have gained some strength. There have been reports of buried surface hoar up to1m down. This layer, which was buried at the end of November, seems most prevalent on the west side of the region. Little is known about its current reactivity.At the base of the snowpack an early November crust which is associated with a layer of facets either directly above or below. Recent tests have shown sudden results at this interface. In general, snowpack data is sparse in this region and significant variations likely exist from one drainage to another. Digging down and making your own observations will be critical to safe slope selection. Any observations from the field are welcome at forecaster@avalanche.ca.
