Avalanche Canada wlewis, Avalanche Canada


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.




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.

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.
