Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
There is a MODERATE danger from loose wet avalanches at middle elevations. As the latest storm develops, rain and warming temperatures could heat and soften middle elevation slopes and increase the loose wet avalanche danger. Be wary of steep, rocky slopes that will heat up quickly and shed their snow first.
