Avalanche Forecast
Regions: Pine Pass.
Avalanche danger will increase through the day as new snow and wind form heavy storm slabs at upper elevations and rain soaks the snow surface at lower elevations.
Confidence
Moderate
Avalanche Summary
A few wind slab avalanches were reported east of Prince George on Thursday. They were skier-controlled size 1.5 on steep north-facing convex rolls, running on the January facet layer.
Observations are limited in the region. If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
20-40 cm of new snow is forecast to fall by the end of the day Saturday. The new snow falls over recent snow that has seen some redistribution by wind at upper elevations, and moist or crusty surfaces at lower elevations.
A layer of facets is now buried 40-80 cm deep. This layer has been observed to be bonding recently but the significant new snow load may have a destabilizing effect in the short term.
The mid snowpack is generally strong and well bonded including a prominent crust buried 50 to 90 cm deep below 1400 m.

Terrain and Travel Advice
- Be careful to keep storm day fever from luring you out into bigger terrain features.
- Storm slab size and sensitivity to triggering will likely increase through the day.
- As the storm slab problem gets trickier, the easy solution is to choose more conservative terrain.
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
Avalanche Problems
Storm Slabs
New snow and wind are forming fresh storm slabs at upper elevations. Storm slabs may become increasingly reactive through the day with rising temperatures.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Very Likely
Expected Size: 1 - 2
Loose Wet
Loose wet avalanches will become increasingly likely at lower elevations as rain soaks the upper snowpack.
Aspects: All aspects.
Elevations: Below Treeline.
Likelihood: Likely
Expected Size: 1 - 2
