The area around Fernie is forecasted to get the heaviest snowfall in this next storm. Avalanche danger will increase through the day as snow falls. Observe how much new snow is piling up as you travel through terrain, and retreat to mellower terrain if you are seeing signs of instability like shooting cracks or recent avalanches.
Storm slabs will be reactive to the weight of a rider earlier in the day, and naturally triggered avalanches may become more likely by the afternoon and into the evening as more snow piles up.
On Saturday, east of Fernie, a couple of small to large natural and rider triggered avalanches were reported that involved cornices. See the MIN report for more information.
Looking forward, fresh storm slabs will be reactive to the weight of a rider earlier in the day, and naturally triggered avalanches may become more likely by the afternoon and into the evening as more snow piles up.
Please continue to share any observations or photos on the Mountain Information Network.
Moderate to heavy precipitation and moderate southwest wind is likely to form reactive storm slabs on the surface.
10 to 20 cm of storm snow from late last week was redistributed by moderate to strong winds which developed wind slabs at treeline and alpine elevations. This overlies a melt-freeze crust below 1900 m
The mid-pack is consolidated in the Lizard Range with a robust, frozen crust buried 70 to 90 cm.
