Snowpack Summary
Recent storm accumulations have been highly variable throughout the region; however, some ares saw moderate to heavy snowfall a few days ago. In general winds have been strong creating widespread windslabs at higher elevations. Warmer temperatures and rain at lower elevations have created moist surfaces that will most likely form a temperature crust with dropping freezing levels. Cornices are also reported to be unseasonably large and potentially unstable.There have been reports of buried surface hoar up to a metre down. This layer, which was buried about a week ago, seems most prevalent on the west side of the region. Little is known about its current reactivity.At the base of the snowpack you may find the early November crust which is associated with a layer of facets either directly above or below.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.
