    Storm slabs continue to develop with each new pulse of Pacific moisture. Incremental loading like this can add a great amount of uncertainty for forecasting avalanche danger.

Confidence

Low - Due to the number and quality of field observations

Weather Forecast

Avalanche Summary

No new avalanches reported.

Snowpack Summary

There is a great deal of variability in the region. The Duffey Lake area has received the most snow and rain during the recent storms, and it has also had the highest freezing levels. The Coquihalla has a shallower snowpack with slightly cooler temperatures. Storm slabs of varying depths are developing above a mixture of old surfaces left behind after the recent high pressure. We have not had many observations from this region, if you are out in the mountains please submit your observations to the Mountain Information Network.
