Weather Forecast

A significant storm is entering the forecast region starting tomorrow. Up to 40cm is expected and this will obviously elevate the danger rating.

Snowpack Summary

Below tree line there is not enough snow for avalanches. Above 1900m a buried rain crust that formed in early November lies 20-40cm above the ground. This along with surface hoar in some areas is being buried by light snow and will create a good sliding layer as the new snow accumulates. Some lee slopes near the divide have thin wind slabs.

Avalanche Summary

No avalanches observed or reported today.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Wednesday
