Weather Forecast

There is up to 25cm recent storm snow and an additional 10cm forecast until the end of day on Sunday. This new snow along with what has fallen so far will keep the avalanche hazard at Considerable in the Alpine.

Avalanche Summary

No new natural avalanche activity was observed.

Snowpack Summary

20-30 cm of storm snow is overlying a buried wind slab. This new snow and the buried wind slab down 50cm are both reactive to snow pit tests in the Alpine. These two layers are certainly a concern for triggering. The November 12th melt-freeze crust is now 40-60cm down from the surface and is still showing a good bond with the snow above.
