Avalanche Forecast
Regions: East Island, North Island, South Island, Vancouver Island, West Island.
Confidence
Moderate
Avalanche Summary
A widespread loose wet avalanche cycle is expected to have occurred throughout the monsoon. Observations have been limited aside from small loose wet activity out of steep, rocky treeline terrain near Arrowsmith and Strathcona on Friday and Saturday.
Natural activity may slow down during the break in rain today, but human triggering remains likely.
Snowpack Summary
Rain has saturated the snowpack to mountaintop. Below treeline, the snowpack has melted out almost entirely, leaving it below threshold for avalanches.
Weather Summary
Monday night
Cloudy with continued rain, south alpine winds 100 km/h, treeline temperature 4 °C, freezing level 2000 m.
Tuesday
A mix of sun and cloud with scattered showers, southwest alpine winds 40-50 km/h, treeline temperature 5 °C, freezing level 2300 m.
Wednesday
Cloudy with heavy rain, southwest alpine winds 80-90 km/h, treeline temperature 5 °C, freezing level 2100 m.
Thursday
Cloudy with moderate rain turning to snow, southwest alpine winds 80-90 km/h, treeline temperature 2 °C, freezing levels around 1500 m.

Terrain and Travel Advice
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
- Keep in mind that human triggering potential persists as natural avalanching tapers off.
- Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
Avalanche Problems
Loose Wet
High water content and low cohesion in the snowpack means loose wet avalanches can be expected in steep terrain.
Natural activity may slow down during the break in rain today, but saturated snow remains primed for human triggering.
