Regions
Little Yoho.
Windslab formation is expected to begin with the new snow tomorrow. Open, lee ridgecrests should be suspect. New snow should make skiing excellent.
Weather Forecast
Daytime temperatures will range from -20 to -10. Some snow (5-15cm) is forecast with moderate winds. We will likely see windslabs form in open areas, in the lee of ridgecrests.
Snowpack Summary
5-10 cm of new snow overlies low density facets that formed near the surface during the current cold spell. These surface conditions can produce dry loose avalanches in steep places, but slab formation has been minimal. The distribution of the Jan 17 SH is spotty, but in some areas (Kootenay) it appears prominent; strength tests are hard & sudden
Avalanche Summary
No new avalanches observed or reported.

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.
