Terrain and Travel Advice
- Watch for fresh storm slabs building throughout the day.
- Storm slab size and sensitivity to triggering will likely increase through the day.
- As the storm slab problem worsens, the easy solution is to choose more conservative terrain.

Avalanche Summary
No new avalanche observed or reported.
If you are heading into the backcountry, please share your observations on the Mountain Information Network (MIN).
Snowpack Summary
Surfaces softened by Tuesday's sun will refreeze with the passage of the winter storm. The new snow is therefore expected to fall on crusted surfaces. The strong to extreme easterly winds accompanying the snowfall are likely to significantly affect snow distribution. The bonding of the new snow to the crust remains to be determined.
The mid-pack of the snowpack is composed of alternating well-settled snow and refrozen crusts. At mid-elevation, the snowpack depth ranges from 60 to 160 cm.

Low
- Forecast precipitation (either snow or rain) amounts are uncertain.
- Uncertainty is due to the extreme variability of wind effect on the snowpack.

For backcountry rescue call 911 and tell them you are in the Chic-Chocs
