Regions: Cariboos.

Avalanche danger has improved since last weekend, but a skier or sledder could still trigger a large avalanche in specific terrain.

Confidence

Fair - Intensity of incoming weather systems is uncertain

Weather Forecast

Saturday: Light snow. Moderate to strong SW winds. A layer of warm air may form at mountain height, while the valleys remain cooler.Sunday: Light snow. Light to moderate S winds. The layer of warm air aloft may persist. Monday: Light snow. Moderate to strong S winds. Warming up at all elevations late in the day.

Avalanche Summary

We haven't had any recent reports of avalanche activity.

Snowpack Summary

Recent reports from the region suggest that 50-150 cm of settling snow overlies one or more weak crust/facet layers which formed during November. Snowpack tests show generally improving strength, but the potential to produce large avalanches if triggered. Forecast winds may build wind slabs on lee slopes.

Avalanche Problems

Wind Slabs

Forecast winds may build new slabs on lee slopes. Watch for breakable, punchy snow or smooth bulbous shaped slopes.
Be cautious as you transition into wind affected terrain.>Highmark or enter your line well below ridge crests to avoid wind loaded pillows.>

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3

Persistent Slabs

The chances of triggering a persistent slab have decreased, but the consequences would be high.
Avoid common trigger zones including thin snowpack areas, near rocky outcrops, and steep alpine slopes.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 5
