As the month long drought ends look for a variety of weak layers to be buried that could cause problems in the weeks to come.
Weather Forecast
The cold ridge of high pressure has finally broke down by a series of lows moving inland bringing warmer moister air and a little precip over the region. Thursday: A mix of sun and cloud. Alpine High -8 C, Low -16 C. Ridge wind Light Southwest gusting ModerateMountain weather forecast available at Avalanche Canada.
Snowpack Summary
10cm of new snow through Thursday and moderate winds could create new windslabs in the alpine. New snow will bury a variety of surface; surface hoar, facets and crusts. The upper snowpack remains generally facetted. The mid and lower snowpack is facetted but still generally carries skis.
Avalanche Summary
No new avalanches have been observed or reported.
Confidence
Timing, track, or intensity of incoming weather system is uncertain
Problems
Deep Persistent Slabs
Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
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.
