A series of Pacific storms will cross the north coast and move inland over then next 4 days with small amounts of precipitation. Tuesday is forecast to bring the most moisture and should leave 5 to 15cm of snow at upper elevations. Dribs and drabs will follow on Wednesday.

Avalanche Summary

No avalanche activity has been reported in the forecast region

Snowpack Summary

In general, the early season snowpack is shallow and weak. The recent 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.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
