Weather models are uncertain to the amount of snow arriving on Monday and Tuesday. A significant amount has potential to increase the danger rating.
Weather Forecast
10-20cm of snow may arrive starting Monday into Tuesday with winds shifting Northerly mid-storm and temperatures dropping. It will be clear skies, cold overnight temperatures, and Northeasterly winds the remainder of the week.
Snowpack Summary
Field observations in the Parkers area found snow depths vary between 10 to 140 cm. Extensive wind effect at TL and above giving supportive touring but limited ski quality out in the open. Where significant loading has occurred the snow remains stubborn and does not want to propagate.
Avalanche Summary
One possible unobserved skier remote, sz 1.5 seen Saturday on a slope in the Hilda-Destiny ridge area. A BTL steep rock slab feature in a cross-loaded gully. Forecasters are treating it as a anomalous event as no further naturals were observed.
Confidence
Timing, track, or intensity of incoming weather system is uncertain on Monday
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.
