Avalanche Forecast
Regions: Blue River, Cariboos, Clemina, McBride, North Monashee, Premier, Quesnel, Renshaw, Robson, Sugarbowl.
Watch for pockets of wind slab forming in high leeward terrain features and be ready to dial back your terrain choices if you see more than 15 cm of new snow.
Confidence
Moderate
Avalanche Summary
A couple of large cornice failures have been observed over the past few days. Both took place in high alpine areas in north-facing terrain. Neither of these failures propagated any weak layers on the slopes below.
Snowpack Summary
A dusting of new snow falls over a widespread melt-freeze crust on all but high north-facing alpine terrain, where dry and/or wind affected snow may persist.

Terrain and Travel Advice
- Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.
- Wind slabs are most reactive during their formation.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
Avalanche Problems
Wind Slabs
Wind slabs are possible where wind has deposited sufficient snow into lee terrain features at upper elevations. Wind slabs may be especially reactive where they sit over a crust.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 1.5
