dsaly,
Avalanche Canada
Avalanche hazard will increase in areas where fresh snow accumulates and wind redistributes loose snow.
Summary
Confidence
Moderate - Forecast precipitation (either snow or rain) amounts are uncertain.

Avalanche Summary
On Saturday, small pockets of loose wet snow were reactive to skiers.
Snowpack Summary
Rain has reached the top of the North Shore Mountains with wet snow falling above 1400 m. A surface crust has formed with cooler overnight temperatures. Dry snow may persist at the highest elevations, and has been heavily impacted by wind. The snowpack is strong and settled from earlier rain, and now 200-300 cm deep around the peaks of the North Shore mountains.
Terrain and Travel
- Minimize exposure during periods of heavy loading from new snow and wind.
- Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
- As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
Problems
Storm Slabs
Storm slabs will build at higher elevations where snowfall accumulates.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
Rain and warm temperatures will encourage wet-loose avalanches in steep terrain at lower elevations.
Aspects: All aspects.
Elevations: Treeline, Below Treeline.
