Weather Forecast
Friday night will be mainly cloudy with flurries, low -3 C, light SW winds, and freezing level 1700m. Saturday will be clouds, sun, flurries, high -3 C, moderate SW winds, and freezing level 1800m. Sunday will bring sunny periods and flurries, -7 to -4 C, 15 gusting 45 km/hr winds, and freezing level 1800m.
Snowpack Summary
The snowpack is trending isothermal in the afternoons on all aspects up to 2100m including N aspects. This condition tapers off as you ascend. North aspects treeline and above is still a winter snowpack. No windslab exists treeline and below but expect to find it high alpine ridgetops on generally East aspects in isolated terrain.

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.
