Regions
Little Yoho.
Ice climbs in Field are in good shape, but the valley bottoms are still a little thin for skiing: ~30 cm of snowpack at Emerald Lake and ~ 20 cm in Field.
Weather Forecast
Thurs-Friday will be a mixed bag of sun/cloud and we may see occasional flurries (up to 5 cm). Cold air pushes into the region Friday night as the winds switch to NW and temperatures drop to -15 to -20 .
Snowpack Summary
The October 26 crust is found ~10-30 cm above the ground. The snowpack averages 40-85 cm at 2200m across the region. The wind slabs described earlier this week seem to be thin on immediate lees and of little consequence unless found on an ice climb.
Avalanche Summary
No avalanches observed or reported.
Confidence
Due to the number of field observations
Problems
Deep Persistent Slabs
Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
