Regular avalanche forecasts are now finished as we transition into Spring Conditions. Use our Weather Stations, the ACMG Mountain Condition Reports, and the Mountain Information Network to stay up to date.
Increasing activity with rising temps, especially during warm and/or sunny afternoons. Use extra caution if the surface hasn't refrozen overnight - clear nights help. Watch for Wind Slabs in the alpine, particularly following snow or rain. Use extra caution if these form above crusts - this often happens into Summer on high peaks, eg Mt Athabasca.
An overview of spring conditions is available on Avalanche Canada website.
Generally, danger increases with daytime warming, & decreases with cold, clear nights. A dry winter snowpack may persist on shady, high alpine slopes.
As the snow thins, crevasse bridges weaken. Use extra care in thin wind-affected areas, eg the Athabasca Glacier.
