Avalanche Forecast
Regions: Glacier.
Weather Forecast
Sunny, warm, light winds, no precip this week. This looks like the first week of Spring. Freezing levels will climb as the day progresses, hitting 2000m today and possibly 2400m tomorrow. The strong STRONG sunshine will make things feel even warmer if you are on a sunny slope.
Snowpack Summary
Yesterday's sun and heat has created a surface crust to ridge-top on solar aspects and further settled the snowpack on polar aspects. Of most concern are the multiple crusts in the top metre of the snowpack, found mainly on sunny slopes. Avalanches may step down to deeper layers if they start moving. Wind slabs can be found in alpine lee features.
Avalanche Summary
The strong heat yesterday from the sun triggered numerous loose avalanches to size 3 from steep alpine and tree-line start zones. Expect to see the same today once the frozen surface crust breaks down this morning. Another glide crack release was observed in Lone Pine on Tupper, reminding folks of the unpredictable nature of these looming threats.
