Below 1,700m this curst is present regardless of aspect. The snowpack at all elevations has a weak base and several mid-pack weaknesses

A widespread avalanche cycle took place on Thursday evening with little overnight freezing this will likely occur again this evening. Numerous point releases from the alpine then triggered wet slabs that ran to ground. The largest events were on south and westerly facing and ran to size 2.5. Fewer slides are occurring on northerly terrain.
