Avalanche Forecast
Regions: Waterton Lakes.
Weather Forecast
Continued Chinook conditions with warm temperatures with light precipitation are forecast for Saturday. Sunday morning winds ease off and switch to the North, temperatures should drop considerably to more seasonal values and we may see moderate accumulations of snow before a clearing trend on Monday.
Snowpack Summary
Moist surface snow below 1900m on all aspects and up to 2100m on solar aspects. Wind slabs present near ridge crests and open areas above tree line. In deep snow areas there are no other persistent weak layers. In thin snow areas facets are present in the snow pack which could be activated by the warm wet weather we are experiencing.
Avalanche Summary
Loose wet slides up to size 1.5 out of steep terrain below tree line were observed today. As things continue to warm up over the next 36hours we may see more avalanches as the combination of wind, warm temperatures and new snow and/or rain, over load cornices, wind slabs and surface snow. As temperatures drop the hazard will also lower.
Confidence
Timing, track, or intensity of incoming weather system is uncertain
