Highlights

A few cm of new snow have freshened things up in sheltered areas but wind exposed areas will still feel a bit firm especially with the cold temperatures. A bit more snow tonight will help and the warmer temperatures forecast for next week will too!

    Isolated pockets of hardslab found in the typical areas of the Alpine like ridge tops, exposed features, or ledges above ice climbs. These may have been buried by a few cm and will be a bit harder to detect

Weather Forecast

Friday remained cold with new 5cm overnight and light winds and trace amounts accumulating through the day. A few  more cm are expected overnight before clearing starts again Saturday. Temperatures will warm slowly through the weekend becoming almost warm Monday while  winds will remain light westerly winds at ridge top through Sunday.

Snowpack Summary

5cm of new snow now buries isolated pockets of wind slab in exposed ALP & TL areas sitting on an old snow interface of facets, sun crust, wind effect, or surface hoar. 3 crusts extend into the lower limits of the alpine and are sitting dormant in the snowpack, the Nov 24 crust is providing mid-pack strength over the lower Oct 31 crust and facets.

Avalanche Summary

No new avalanches have been reported or observed along the parkway.Explosive control at the local hill on Christmas Eve produced a few small avalanches from isolated pockets of wind slab.
