Avalanche Forecast
Cariboos
This forecast is based on very few field observations. This high level of uncertainty warrants conservative terrain selection.

- Be cautious as you transition into wind affected terrain.
Avalanche Problem 2: Persistent Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Not much is known about the reactivity of a hard crust which lurks deep in the snowpack. This uncertainty warrants conservative terrain selection as an avalanche at this interface could be large and destructive.
Travel and Terrain Advice
- Avoid exposure to avalanche terrain during periods of rapid loading by rain, snow, or wind.
Avalanche Summary
No new avalanches were reported in this region. This may speak to a lack of observations rather than actual conditions. With forecast wind and snow, a natural storm slab avalanche cycle is expected on Wednesday night and into Thursday.
We currently have very limited observations from this region. Please submit your observations to the Mountain Information Network (MIN).
Snowpack Summary
Up to 30cm of new snow has fallen in the past few days. At higher elevations, southerly winds (gusting strong at times) likely redistributed the new snow, forming wind slabs on lee features.
Below the recent storm snow you may find a couple of crusts which formed during last week's rain. That said, little is known about the reactivity of these crusts or the elevation bands at which you're likely to find them.
A major feature in the snowpack is a crust which formed around November 11th and can be found approximately 100cm down at treeline elevations. We currently have very limited snowpack observations within this region and it is critical to supplement this information with your own observations.
The depth of the snowpack varies greatly with elevation. Recent reports suggest the average depth is 200+cm in the alpine, 100-160cm at treeline, and decreasing rapidly below treeline where the primary hazards are rocks, stumps, and open creeks.
Weather Forecast
Wednesday evening: 5-15cm of new snow / Moderate southwest winds / Freezing level at 1100m
Thursday: 8-15cm of new snow / Moderate southwest winds / Freezing level at 1100m
Friday: 3-5cm of new snow / Light southerly winds / Freezing level at 1100m
Saturday: Mix of sun and cloud / Light southerly winds / Freezing level at 700m

New wind and snow on Wednesday night and Thursday will form reactive new storm slabs. Surface avalanches may "step down" to buried weak layers resulting in surprisingly large avalanches.
