Forecast Details

Weather Forecast

The Mountain Weather Forecast is available from Avalanche Canada (https://www.avalanche.ca/weather/forecast).

Detailed local forecasts are available from sites like SpotWX (https://spotwx.com/)

Snowpack Discussion

An overview is available: (https://www.avalanche.ca/pages/static-page/summer-conditions)

Generally, danger increases with daytime warming, & decreases with cold, clear nights.

As the snow thins, crevasse bridges weaken. Use extra care in thin wind-affected areas, eg the Athabasca Glacier.

Avalanche Activity Discussion

Avalanches can occur all year on high peaks. Avalanche activity increases with fresh snow, rising temps, especially during warm and/or sunny afternoons. Use extra caution if the surface didn't freeze overnight.
