Summary
Weather Forecast
Depending which weather forecast you believe we could see 5-10cm today. I'm going with the hopeful 10cm. Alpine high of -15C and NE winds up into the moderate range are expected. Cold arctic air is forecast to push in overnight with an alpine high tomorrow of just -21C with light easterly winds.
Snowpack Summary
10-15cm of settled, faceted snow resides on old wind slabs in sheltered areas. Moderate to strong winds have deposited thin wind slabs on exposed terrain features at ridge-top and exposed areas BTL. A crust on steep solar aspects makes for difficult traveling conditions, both uphill and down. The mid and lower snowpack is well settled and strong.
Avalanche Summary
Two size 1 skier accidental wind slabs were reported on MIN Wednesday one from the Thorington route. The second was a skier accidental involvement size 1 in Cougar Creek East with enough mass to nock the skier over.
Confidence
Due to the number of field observations
Problems
Wind Slabs
Previous moderate to strong winds and cold temperatures have been promoting wind slab development. Reactive wind slabs are occurring in isolated areas, these slabs may be overlying old dormant wind slabs or weak facetted snow.
Watch for whumpfing, hollow sounds, and shooting cracks.Watch for pockets of hard windslab in steep alpine features.
