Storm slabs may be possible to trigger at high elevations where dry snow has been loaded into leeward terrain features.
Ease into terrain on Monday. Verify conditions as you travel and tune into any signs of instability.
Storm slabs may be possible to trigger at high elevations where dry snow has been loaded into leeward terrain features.
There have been no recent reports in the region. We suspect the likelihood of avalanches has decreased substantially since the storm on the weekend, but rider-triggered storm slabs may still be possible at upper elevations on Monday.
If you are going out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
At upper elevations, 20 to 40 cm of snow from the weekend is expected to bond well. At lower elevations, a crust develops over a rain-soaked snowpack.
Snow depths at treeline vary across the region. Around 90 cm is reported in the Coquihalla and 60 cm near Manning Park.
