A widespread weak faceted base is the root of all concern. Be very cautious in all steep terrain for slab and loose snow avalanches.
Weather Forecast
Clear warm conditions with light winds expected until Tuesday night then there is the potential for some snow (up to 10 cm) with moderate SW winds. (Don't hold your breath)
Snowpack Summary
SW (M-S) winds have built slab on top of a weak faceted snowpack on exposed tree line and alpine features. Mid-pack starting to loose strength. Very weak faceted snowpack below tree line.
Avalanche Summary
A couple of sz 2.5 slab avalanches in the alpine (a cornice and natural) on south and NE aspects south of the Icefields along the Parkway observed on Saturday.
Confidence
The weather pattern is stable on Monday
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.
Loose Dry
Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
