Avalanche Forecast
Regions: North Shore, South Coast, Tetrahedron.
Minimize your exposure to steep, south facing slopes.
Rising temperatures will increase the potential for wet avalanches. Hazard is expected to reach considerable on sun affected slopes.
Confidence
High
Avalanche Summary
On Thursday reactive slabs were observed on all steep slopes, reactive to human triggers. On Saturday, we expect sunshine and warm temperatures to create ideal conditions for wet snow avalanches.
If you head into the backcountry, please submit any observations or photos to the Mountain Information Network, observations are limited in the spring.
Snowpack Summary
15-30 cm of recent snowfall is moist to wet from warm temperatures and sun. This snow will likely slide easily on the widespread crust below.
Below treeline elevations have minimal snow cover, if any at all. Expect challenging travel conditions with hazards like rocks, stumps and open creeks.
Weather Summary
Friday Night
Clear skies. 10-20 km/h westerly ridgetop wind. Freezing level climbs overnight to 2300 m.
Saturday
Sunny. 10-15 km/h southwest ridgetop wind. Treeline temperature reaches a high of +9 °C. Freezing level remains around 2500 m.
Sunday
Mostly sunny. 20-40 km/h west ridgetop wind. Treeline temperature +3 °C. Freezing level drops over the day to 2000 m.
Monday
Mostly sunny. 40 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level around 1000 m.

Terrain and Travel Advice
- Avoid sun exposed slopes, especially if snow surface is moist or wet.
- A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
Avalanche Problems
Loose Wet
Expect wet slab and wet loose avalanches on all steep, sun affected slopes as temperatures rise. Avalanches are expected to initiate easily on the crust below.
Aspects: South East, South, South West, West.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1 - 2
Storm Slabs
Storm slabs are expected to remain reactive to human triggers. Around ridgelines, deeper deposits can likely be found on north facing slopes.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 1.5
