Avalanche Canada
Overnight snow and wind will form fresh storm slabs that are expected to become increasingly reactive throughout the day; especially in wind affected terrain. Choose very conservative terrain away from overhead hazard.
Summary
Confidence
Moderate - Uncertainty is due to the timing, track, & intensity of the incoming weather system. Forecast snowfall amounts are uncertain.

Avalanche Summary
No new avalanches were reported in this region on Tuesday.
Snowpack Summary
The new snow is not expected to bond well to the hard crust now caps the snowpack up to the tops of the North Shore mountains. The new storm slabs are expected to be most reactive in wind affected terran. High elevation terrain in other parts of the region could have up to 50 cm of recent snow, likely heavily wind affected. However there are no observations to confirm alpine conditions.
Terrain and Travel
- Avoid all avalanche terrain during periods of heavy snowfall.
- Storm slab size and sensitivity to triggering will likely increase through the day.
- Expect slab conditions to change drastically as you move into wind exposed terrain.
- Be careful to keep storm day fever from luring you out into bigger terrain features.
Problems
Storm Slabs
New snow and wind are expected to form touchy storm slabs reactive to human triggers; especially in wind affected terrain.
