Rugged travel conditions are the most readily found hazard.
Cornices triggers are becoming less likely but may trigger slabs in dry snow or through a thin crust.
Large, looming cornice failures are becoming less likely in cooler temperatures but these large loads are destructive and can trigger lingering wind slabs on slopes below.
No new avalanches reported in the region.
On Thursday and Friday, a number of cornice/ice falls triggered large wind slabs, size 2 to 2.5, in extreme terrain in the high alpine.
A widespread melt-freeze crust extends up to at least 1600 m and as high as 2200 m. This crust may soften on steep south-facing slopes during the day. On all but southerly aspects in the high alpine, snow is dry and wind affected. Cornices loom large.
A crust/facet layer from mid-December exists in the mid snowpack. Triggering this layer is unlikely, except with large loads or in thin snowpack areas.
