Finally, a storm is on the horizon! Although precipitation amounts look to be minimal, increasing winds will raise the danger on Tues and Wed. Enjoy the "Green Brick" while it lasts!
Weather Forecast
A system is moving in and Monday will see clear skies with alpine winds increasing to moderate from the W/NW. Tuesday through Thursday we should see some light precipitation with moderate W winds and temperatures in the -5 to -15 range.Check our weather stations for current conditions.
Snowpack Summary
3-10cm of low density snow sits over the Jan 6 interface of surface hoar, facets and sun crust (buried on steep S aspects). Thin, Isolated wind slabs exist in the alpine near ridge crests. Below 2000m the Dec 3 layer of surface hoar and facets remains visible down 20-50 cm but is currently dormant. Thin areas are faceting out and weakening.
Avalanche Summary
No new avalanches observed or reported today
Confidence
Timing, track, or intensity of incoming weather system is uncertain on Tuesday
Problems
Loose Dry
Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
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.
