Recent snow accumulation and wind loading have formed fresh slabs. Seek conservative terrain choices that avoid north-aspect terrain.
Continued wind and available snow has formed wind slabs in areas just below ridgetops, at the top of gulleys, and at the base of steep features.
Expect new and weak cornice formation at ridge tops and at the top of gulleys.
No new avalanches have been reported or observed.
New accumulations between 10 cm and 15 cm overlie a thin snowpack. Upper elevation terrain in the direct lee of the past south wind harbors pockets up to 50 cm to 70 cm in depth with upper Alpine terrain nearing 100 cm in depth.
Coverage is minimal with many early seasons hazards such as thinly buried rocks and trees, open creeks, and weak lake ice.
Expect wind-transported snow to have formed wind slabs in the immediate lee of terrain features. Exposed upper windward terrain will continue to remain stripped down to old surfaces.
