Snowpack Summary
A strong, localized wind event has scoured the majority of our terrain. Areas that still hold snow will have pockets of windslab and heavy loading. New windslab overlies a variety of bed surface including bare ground, old windslab and a melt freeze crust where snow from the late Sept. snowfall did not melt out. Snowpack depth varies from 0 -90 cm.
Avalanche Summary
No new avalanches observed.
Confidence
Due to the number and quality of field observations
Problems
Wind Slabs
Any terrain with a skiable snowpack will likely have Windslab. Our last storm was accompanied by NE winds. We have now returned to a typical SW flow. The combination of these two events has seen Windslab development on all aspects.
- Be careful with wind loaded pockets. Be aware of wide variation in snowpack depth
- Watch for shooting cracks or stiffer feeling snow. Avoid areas that appear wind loaded.
Aspects: All aspects.
