Avalanche Forecast

Expect a mix of sun and cloud from Monday to Wednesday. Ridgetop winds will remain mainly light while freezing levels will climb gradually from 1900m on Monday to about 2400m by Wednesday.

Most commercial operations have closed for the season, and data is becoming sparse. If you have any avalanche activity to report, please consider sharing through the Mountain Information Network.

Monitoring the snow surface is very important during the spring. If the snow surface does not freeze overnight or if the crust is only a few cm thick, the effect of daytime heating, rain or solar radiation will weaken the snowpack much more quickly than it would if there is a well frozen thick crust. Deeply buried weak layers in the mid snowpack and near the ground still have the potential to wake up and become active with a rapid warm up. While unlikely, releases on these deeply buried weak layers would result in very large avalanches. Glide cracks are widespread, active, and best avoided. Cornices are large, fragile, and could trigger deep slab avalanches that run to valley bottoms. The snowpack in many areas has become isothermal, meaning the snowpack is 0 degrees Celsius throughout. An isothermal snowpack is more prone to full depth wet slab avalanches during the heat of the day.
