At the mid and upper elevations buried layers of surface hoar and areas with poor snow structure exist. Humans could trigger large slab avalanches on buried persistent weak layers. Evaluate terrain and snowpack carefully. Avalanches are unlikely at the lower elevations.
In steep terrain at the mid and upper elevations slab avalanches 1 to 3 feet in depth could be triggered by humans on persistent weak layers of faceted snow.
A couple of weak systems will move through the region and bring periods of light snow to the mountains. Accumulations of an inch or so are possible overnight with another couple of inches likely by Wednesday evening. Temperatures will be in the teens and 20s. Southerly winds will veer to the southwest and be light at 10 to 20 miles per hour.The general avalanche hazard is expected to be moderate at the mid and upper elevations (7,500 to 10,500 feet) on Wednesday. Large slab avalanches with depths from 1 to 3 feet could be human triggered on steep slopes. The failure planes for these avalanches would be weak buried layers of faceted snow. Evaluate terrain and the snowpack carefully. Avalanches are unlikely below an elevation of 7,500 feet where the general avalanche hazard is expected to be low.
