You may find touchy wind slabs on all aspects in exposed terrain features.
Summary
Confidence
Moderate - Uncertainty is due to the limited number of field observations.
Weather Forecast
TUESDAY NIGHT: Clear skies, 20 km/h north wind, alpine temperature -26 C.
WEDNESDAY: Increasing clouds over the day with afternoon snowfall, accumulation 1 to 3 cm, 20 to 40 km/h northwest wind, alpine temperature -25 C.
THURSDAY: Cloudy with snowfall, accumulation 5 cm, 20 to 40 km/h southwest wind, alpine temperature -26 C.
FRIDAY: Mix of sun and cloud with no precipitation, 15 km/h north wind, alpine temperature -26 C.
Avalanche Summary
No recent observations are available for the Cariboos. It is suspected that wind slabs are triggerable by riders.
We'd appreciate if you submit your observations to the Mountain Information Network, even just a photo.
Snowpack Summary
Cold air continues to facet the top of the snowpack. Elevated wind on Wednesday may produce new wind slabs on south to east aspects. Old wind slabs may still linger given the cold air, meaning wind slabs may be found on all aspects.
Sugary faceted grains above and below the early-December melt-freeze crust is around 60 to 100 cm deep. The layer exists up to around 2000 m. This layer is spatially variable, with many areas showing good bonding to the crust whereas others still being of concern. Learn more about how to manage this problem here.
Terrain and Travel
- Carefully evaluate steep lines for wind slabs.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
Problems
Wind Slabs
New wind slabs are expected to form on south to east aspects over the course of Wednesday. Lingering wind slabs may still exist on northerly aspects, meaning you could trigger a slab on all aspects.
Aspects: All aspects.
