    there is still a chance for significant sluffing with the new storm snow. Be aware of loading on S aspects with northerly winds.

Weather Forecast

Cold and clear with light north winds through till end of week at least.

Snowpack Summary

10-15 cm of Storm Snow has fallen over last 48 hrs. Strong Northerly winds caused some reverse loading and fresh wind slabs with the arrival of the Arctic front. Steep gullies and large open start zones at and above treeline should be treated as suspect until this storm snow settles. Cold temperatures should promote a stabilizing trend.

Avalanche Summary

No new avalanches have been observed.

Confidence

Due to the quality of field observations
