Avalanche Summary
No new avalanches reported.
Snowpack Summary
Forecast new snow and Southwest wind may result in a new storm slab. High freezing levels may limit crust recovery before the new snow arrives. There are a few crusts in the snowpack that we are following. The March 25th crust is now down about 20-30 cm buried below a well settled layer of recent snow. The March 10th crust is buried down 60-90 cm and is reported to be widespread across the region up to about 2000 metres elevation. The facet/crust persistent weakness buried at the beginning of February is now down 70 - 200cm, and has been highly variable in terms of reactivity. In areas where the strong and supportive crust exists, triggering this layer has become unlikely. Avalanches releasing on this deeply buried weak layer could be very large and destructive.
