Weather Forecast
Expect seasonal temperatures next few days with a slight daytime warming trend continuing Sunday. Consistent moderate westerly winds continue through Sunday making it unpleasant to tour in the open. Monday afternoon forecast still calling for 10-15 cm of storm snow. Be observant of the impacts of previous wind and the resulting stiffening slab.
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. This was the case on a heavily cross-loaded open west aspect.
Avalanche Summary
One possible unobserved skier remote, sz 1.5 seen today on a regular performing 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 evidence in the surrounding area supports that snowpack character but, still a high consequence event.
