The storm Saturday night may see enough new snow to start increasing the avalanche hazard at higher elevations.  Climbers and skiers should keep an eye on this through the weekend as the new snow will be sitting on a well developed layer of facets.

Summary

Weather Forecast

20-30cm of new snow is expected at higher elevations over the weekend.

Snowpack Summary

Up to 50cm of snow is present at higher elevations and the facetting process is well under way. In places a thin wind slab exists over the facets.  New snow over this layer is likely to be fairly reactive.

Avalanche Summary

No new avalanche observations in the past ten days.

Confidence

Intensity of incoming weather systems is uncertain on Saturday

Problems

Wind Slabs

Generally these thin wind slabs will be difficult to trigger however the consequences of a small slide in steep rocky terrain could be serious so use caution in these spots.
Be careful with wind loaded pockets while approaching and climbing ice routes.
