Steady snowfall throughout the week is expected.
Weather Forecast
Steady snowfall expected during the week, increasing in intensity by next weekend. Winds light to moderate from the Southwest. Temps warming up from the recent arctic condition but remaining cool with daytime highs in the -2C range at treeline. Freezing levels reaching 2000m by mid-week.
Snowpack Summary
Supportive mid-pack above 1900m. A persistent weak layer (Feb10 interface) can be found down 30-70cm and consists of decomposing surface hoar and or facetted grains. This appears to be bonding well and is mainly a concern on solar aspects (South and West). Recent moderate winds have created new windslabs in open areas above tree line.
Avalanche Summary
No new avalanches have been reported.
Confidence
Intensity of incoming weather systems is uncertain
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.
