    Storm slabs continue to develop with incremental loading above a variety of old surfaces.

Weather Forecast

Flurries or periods of light snow are forecast overnight combined with moderate westerly winds. Freezing levels should remain at valley bottoms due to an Arctic ridge slowly descending from the north. Unsettled with flurries on Saturday with light to moderate southerly winds. Winds increasing Saturday night as some moisture and warmer air try to push up from the major storm on the south coast.

Avalanche Summary

No recent avalanches have been reported. Thin new storm slabs are expected to develop with forecast snow and wind.

Confidence

Poor - Due to the number and quality of field observations

Snowpack Summary

In general, the early season snowpack is shallow and weak. Developing storm slabs are sitting on a mix of crusts and weak facetted crystals or surface hoar in some parts of the region. The southwest of the region sounds like it has the most snow, and probably the most wind with the new snow. We have some reports of a weak facetted base layer in the north of the region where recent temperatures were quite cold during the arctic outbreak. If you get out into the mountains, please submit your observations using the Mountain Information Network.
