The Cold Persists! The good news is that we should receive a light dusting of new snow. Every little bit helps!
Weather Forecast
A light dusting of new snow, between 5.2 and 7.6 cm is expected Thursday night and into Friday. However alpine temperatures will remain low at around -22 C to -18 C. Friday will remain mainly cloudy with isolated flurries, alpine temperatures: -24 C, High -19 C. Winds will remain light Northerly at ridge top until Sunday.
Snowpack Summary
Isolated pockets of wind slab will be found in exposed areas at upper elevations over the old snow interface of facets, crusts, wind effect, or surface hoar. There are 3 crusts, found generally at TL and the alpine, that sit dormant in the snowpack. The Nov 24 crust seems to be providing mid-pack strength over a lower, rotted, Halloween layer
Avalanche Summary
No new avalanches have been reported or observed along the parkway
Confidence
Due to the number of field observations
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.
