Some new snow in the forecast for tomorrow. The skiing may be refreshed and quite good with dust on crust. A reminder that the bulletins will be phased out in the next while as spring continues. MM
Confidence
Fair - Intensity of incoming weather is uncertain on Monday
Weather Forecast
A cooling trend will bring some convective snow to the area over the next 12 hours. Typical with convective activity, the amounts are uncertain but there could be up to 12cm by tomorrow afternoon. Ridge winds will be strong from the NW.
Avalanche Summary
No new observations
Snowpack Summary
up to 5cm HN in alpine areas that has ben redistributed by moderate to strong NW winds. New windslabs suspected in isolated terrain, but for the most part the storm snow has been blown clean. A thick and supportive melt/freeze crust is exposed up to 2500m. Isothermal snow below treeline by early afternoon, even with heavy cloud cover. Compression tests on a windward aspect had moderate results on a crust down 28cm on depth hoar, 2440m.
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.
