Regions
Banff Yoho Kootenay.
Pay attention to how warm it is getting. If the sun comes out the hazard will increase rapidly on solar aspects.
Weather Forecast
Mixed sun and cloud for Monday with freezing levels near 2000 m. Cooling trend, unsettled weather and light flurries forecasted for Tuesday.
Snowpack Summary
40-50 cm of recent storm snow at treeline lies overtop of previous moist surfaces and in some areas a weak but supportive melt freeze crust. Storm snow is becoming moist at lower elevations and on solar aspects is sluffing out of steep terrain. There may be some fresh wind slabs lingering near lee ridge tops.
Avalanche Summary
Moist loose avalanches up to Class 2 sluffing out of steep and very steep terrain. No slabs observed.
Confidence
Freezing levels are uncertain
Problems
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.
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.
