Avalanche Summary

No new avalanches were observed or reported on Wednesday.

Snowpack Summary

North-facing aspects above 2600 m hold dry, wind-affected snow. On solar aspects, a crust extends to ridgetop and has been weakening under daytime heating. As a cooling trend moves into the region, a widespread surface crust will lock in the snowpack everywhere except on high north-facing terrain.

Weather Summary

Temperatures will fall to below freezing at valley bottom and -10 to -15C at treeline. Some light snow mainly along the East slopes (5-10cm) will end during the day Thursday, and winds will be light to moderate.

Cold with light snow may continue for Friday and Saturday, with an upslope component.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
