Snowpack Summary
Recent snowfall accumulations across the region have been highly variable; however, as of Friday some areas had over 30cm overlying a variety of surfaces that formed during last week's dry spell. These surfaces may include well-settled storm snow and surface hoar. Relevant wind data has been extremely limited; however, some information suggests that winds have been in the moderate range. Forecast snow and increased wind values on Friday night and Saturday will add some more punch to this developing storm slab. There may be a thin buried surface hoar layer down about 115 cm. As well, the November rain crust now exists over 125cm down in some locations and may exist in combination with facets. These layers seem to have been unreactive in recent days, but may have the potential to 'wake-up' with additional loading.Average snow depths at treeline seem to be between 140cm and 170cm.Snowpack data is sparse in this region and significant variations likely exist from one drainage to another. In short, 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.
