While warm and windy conditions have kept snow accumulation to a minimum, be aware that some avalanche hazard does exist. Visitor Safety technicians will start producing regular Avalanche Bulletins each Tuesday and Friday beginning on December 1.
Weather Forecast
Expecting continued warm temps with minimal accumulations
Snowpack Summary
Warm temperatures and strong winds have persisted for the last week Minor accumulation amounts for this period above 1500m only. S and W slopes are largely scoured. HS at LP has settled to one half its original value.
Avalanche Summary
None - Of note however are the collapse of many water ice routes: Expert's Choice, Quick and Dirty ,Compound Slabs, etc have all gone from nearly formed to total collapse in the last 48hrs.
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.
