Strong winds are drifting new snow into cohesive slabs creating dangerous avalanche conditions. Though the storm underproduced, you still run the risk of triggering a slide in the new snow that can step down into layers buried up to three feet deep. You can trigger these larger, more destructive slides from thinner spots in the snowpack that are now obscured by freshly drifted snow. Strong winds may have loaded snow further down on slopes so watch for and avoid wind-drifted areas. These can be identified by their smooth, bulbous appearance and can be on steep rollovers and gullies. Sticking to terrain less than about 30 degrees with no steep terrain above can keep you safer.
