Snowpack Summary
As of Friday, between 20-30cm of recently fallen snow sits over a variety of surfaces that may include surface hoar, a sun crust on steep solar aspects, and well settled storm snow from last week. Forecast wind and snowfall for Friday night and Saturday should significantly increase the size and reactivity of this developing wind/storm slab.Deeper in the snowpack you might find a thin, spotty surface hoar layer about 85cm down. As well, the early November rain crust now sits over 100cm down in most locations (at treeline and above) 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'.The snowpack depth in the alpine ranges from 130-225 cm. Treeline near 150 cm.
