Chinook conditions are expected to occur this weekend so its going to get warm and windy! Ice climbers, keep an eye on overhead terrain. Sluffs can quickly grow to a big size and knock you over.
Confidence
Poor - Due to limited field observations
Weather Forecast
Chinook conditions expected to occur this weekend. Expect to see winds increase into the strong range throughout the day on Saturday peaking in the evening. Very little precipitation is expected with this event.
Avalanche Summary
A few loose wet avalanches up to size 2 occurred with the rain and wind event on Thursday Nov 1st.
Snowpack Summary
Recent rains have created a breakable rain crust up to 2350m in areas along the divide. Further east out towards Highwood pass and the Rae Glacier, this crust extends to higher elevations.
Problems
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.
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.
