Avalanche Summary

No new avalanches reported.

Snowpack Summary

There is about 5 cm of light dry new snow that has buried the melt-freeze crust that developed last week. The crust has been reported to be very hard with no foot penetration on solar aspects, and variable with a 10-15 cm foot penetration on shaded North aspects. There was widespread surface hoar at and below treeline before the new snow arrived, and can be found well preserved below the thin layer of new snow. Cold alpine temperatures are facetting the near surface snow at higher elevations. Some pockets of very soft slab have developed due to wind transported new snow. Deeply buried weak layers continue to exist, however the bridging effect of the re-frozen upper snowpack may reduce the likelihood of triggering.

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.
