Watch for a building temperature inversion and changing surface snow conditions especially on solar aspects.
Weather Forecast
Freezing levels will rise today along with strong solar input on southerly aspects. A strong inversion is moving in and will be the point of focus through Friday. Cloudy with sunny periods today and an alpine temp of -2C with light winds. Alpine temp up to +5C tomorrow and possibly 6C on Friday.
Snowpack Summary
Last week's 50cm of storm snow is providing good skiing accept in wind affected areas. Novemeber 26-23 crusts are down 60-80cm and giving hard progressive collapse results and breaks around the lower more faceted crust. These test results may change with the forecast warming trend over the week.
Avalanche Summary
Recent natural size 3 slab E aspect, 2400m off the Dome ridge, estimate150m wide, 200cm deep ran 200m. Probably down to basal ice. 1 size 1 slab off a small convexity on Video Peak. No new avalanches were observed in the highway corridor yesterday.
Confidence
Freezing levels are uncertain on Wednesday
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 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.
