Regions
Banff Yoho Kootenay.
Another weak storm will create some more isolated windslabs on steep alpine slopes. Otherwise, the crusts will be intact and strong for much of the day. A significant warm up towards the end of the week may trigger a spring cycle.
Weather Forecast
A weak storm will bring a little bit of snow to higher ground. Temps initially will be cool heating up considerably later in the week.
Snowpack Summary
Cooler temperatures have refrozen the snowpack. Upper elevations have new fresh snow and some windslabs.
Avalanche Summary
There have been a few cornice falls and steep wind slabs reported over the last week. All on steep terrain and not running very far.
Confidence
Freezing levels are uncertain on Thursday
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
