    The deep, persistent weakness remains in the snowpack. This problem appears dormant until the next big warm spell, but we continue to note it's presence.

Weather Forecast

Mixed clear skies and some clouds overnight should result in another good surface freeze on the snowpack. Friday looks like a repeat of Thursday, with mixed sun and clouds and freezing levels rising to 2100 m. No new snow expected, and highs of +1 expected for Friday afternoon.

Snowpack Summary

Clear skies and overnight temperatures below freezing should result in a strong surface crust on Friday morning. This crust exists up to 2300m, above where 10cm of dry powder overlies a dry, winter snowpack. Isolated windslabs were reported in the high alpine (3000m) near ridges. Conditions are solid, but watch for deterioration in the afternoon.

Avalanche Summary

No new avalanches were observed or reported today.
