Look to sheltered areas at lower elevations for good turns. Wind slabs are widespread at upper elevations. Use caution in shallow snowpack areas where triggering of the wind slabs is more likely.

Summary

Confidence

Good

Weather Forecast

Cool air will move into the region for a couple of days bringing cold temperatures and light northerly winds. No precipitation is expected for at least the next few days. A warming trend is expected to push into the area sometime on Friday.

Avalanche Summary

No new avalanches were observed or reported.

Snowpack Summary

Between 5 and 10cm of new snow has fallen in the last 24hrs with light to moderate ridge-top winds. This additional snow has had very little impact on the snowpack. Previously formed wind slabs are widespread through Alpine terrain and open areas at Treeline. Expect to find dense wind slabs in all lee and cross-loaded features, except in sheltered areas at lower elevations.

Problems

Wind Slabs

Dense wind slabs are common in Alpine terrain and in open areas at Treeline, especially in lee and cross-loaded features. Steep and/or convex terrain with shallow snowpack characteristics are potential trigger points.

Avoid unsupported slopes.>Avoid cross loaded slopes at or above treeline.>Avoid convexities or areas with a thin or variable snowpack.>

Aspects: North, North East, East, South East, South.
