We aren't expecting snow, but we are expecting the winds to pick up at all elevations. Expect windslabs to be forming in the alpine and exposed treeline areas.
Weather Forecast
Cloudy with clear periods and isolated flurries tomorrow. Ridge winds westerly at 40km/hr. Temps should be a bit cooler with the freezing level well below valley floor.
Avalanche Summary
Nothing new
Snowpack Summary
The warm temps continued overnight which helped to settle the surface snow. As a whole, the low elevation snowpack is still weak. Especially around trees or exposed rocks. Treeline conditions have changed very little in the last 24 hours. The upper snowpack is weak, but the mid to lower pack is stronger and able to carry the weight of a skier. The Dec 15 & Nov 27th layers are apparent, but not reacting to moderate loads at this time. The warmer temperatures and clear skies have created suncrusts and moist snow on all solar aspects. The alpine winds picked up overnight as well and began to create windslabs in exposed areas above treeline.
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.
