Jasper.
A little bit of fresh snow has improved ski conditions. Watch for daytime heating destabilizing the surface snow.
Weather Forecast
Friday will be a trace of snow and -1 C, mainly cloudy, SW 10-30km/hr winds, and freezing level 2200 meters. Saturday will be cloudy with sun and isolated flurries, trace of snow, and Alpine temperatures Low -5 C and High -2 C, with freezing level 1800 meters. Sunday may bring 13cm of snow and gusting 50km/hr winds.
Snowpack Summary
Last night's 5-10cm of fresh snow covers the recent melt-freeze crust. Below treeline the snowpack is trending isothermal in the afternoons depending on the overnight freeze. Higher elevations maintains softer snow with on-going multiple melt-freeze cycles. On north facing alpine slopes up to 15cm of surface snow overlies previous old dry surfaces.
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.
