Light winds and no precipitation for the forecast period.Thursday: Mostly clear with light winds and freezing levels down to the valley bottoms. Cooler in the alpine as the warm air moves to the Southeast.Friday: Becoming cloudy during the day with moderate westerly winds as a weak upper disturbance slides into the region.
Avalanche Summary
Explosives control released cornices on North aspects in the alpine. Cornices that fell onto slopes below did not release slabs.
Snowpack Summary
There is a mix of new surface hoar layers and thin light snowfalls that have buried these layers. Some wind slabs have developed as the recent snow has been transported into the lee of terrain features at higher elevations. The mid layers of the snowpack have settled and are generally reported to be strong. Weak layers that were developed in November continue to show results in tests, but have not been reactive. Thin snowpack areas are the most likely place for deeper layers to be reactive to the additional load of a skier or rider.
