Slightly cooler and cloudier conditions are expected. We shouldn't see much precipitation, but if we do then danger could be higher.
Confidence
Fair - Due to the number of field observations
Weather Forecast
Check out the weather tab above for the detailed synopsis.Wednesday: Mainly cloudy with a slight chance of showers or flurries. The freezing level starts near 3000 m and should lower to 2200 m by the end of the day. Winds are moderate to strong from the SW. Thursday: A mix of sun and cloud. The freezing level is steady around 2200 m and winds are moderate from the SW. Friday: Mainly sunny. The freezing level spikes to 3000 m and winds are light.
Avalanche Summary
On Sunday, a skier-triggered slab released on a weak layer near the ground in Kananaskis Country. Otherwise there has been no new avalanche activity reported from the region.
Snowpack Summary
The snow surface consists of wind-affected snow or wind-scoured crusts in exposed alpine areas, moist snow or sun crust on sun-exposed slopes, or 5-10cm of dry snow overlying an old crust in shady and sheltered areas. At higher elevations, recent winds may have built thin wind slabs in leeward features. Lower elevations are undergoing daily springtime melt-freeze cycles. The most prominent snowpack feature is a thick supportive crust 10-30cm below the surface. It extends up to around 2200m elevation. Below this elevation the crust is effectively capping the snowpack, preventing riders from stressing deeper persistent weak layers. In alpine areas where the crust is not present or is less thick, dormant persistent weak layers may still be lingering and could wake-up with heavy loading or strong warming.
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 Wet
Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
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.
