Large slab avalanches could be triggered by humans on steep slopes with poor snow structure. Steep slopes that were wind loaded during the last storm are most likely to to be unstable. These unstable slabs lie upon weak faceted snow and could be triggered by the weight of a single person. Evaluate terrain and snowpack carefully. Avalanches are unlikely below an elevation of 7,500 feet.
In steep terrain above an elevation of 7,500 feet persistent slab avalanches 1 to 3 feet in depth could be triggered by humans on buried weak layers of faceted snow.
( Discussion is generated from the previous day's afternoon forecast. )The dry weather will continue through most of Tuesday. In the afternoon clouds will begin to increase ahead of a weak Pacific system. At elevation temperatures will drop in to the low teens tonight and rise into the upper 20s on Tuesday. Valley temperatures will drop below zero and then rise into the low 20s. Winds will be from the south-southwest and increase from 5 to 10 miles per hour.The general avalanche hazard is expected is to be moderate at the mid and upper elevations and low below an elevation of 7,500 feet. In steep terrain at the mid and upper elevations humans could trigger large slab avalanches up to three feet in depth on buried weak layers of faceted snow. Evaluate terrain and the snowpack carefully.
