AVALANCHE DANGER MORNING AFTERNOON
GENERAL AVALANCHE ADVISORY
At the mid and upper elevations strong west and northwest winds during the past several days have created shallow pockets of wind slab on a varierty of aspects that have been easily triggered by skiers in steep avalanche prone terrain. Older wind slabs up to three feet in depth lie in some areas on faceted snow and could also be triggered by skiers or riders. On steep northerly aspects above an elevation of 9,000 feet these slabs could step down to the ground. Avalanches are unlikely at the lower elevations.
Recent west to northwest winds have formed pockets of dense wind slab up to two feet in depth. In addition older wind slabs up to three feet in depth remain from last weeks storm. In some areas these older slabs lie upon buried layers of faceted snow that formed in late November. If these surface slabs are triggered on steep northerly aspects above an elevation of 9,000 feet they could step down to the ground.
Weak faceted snow exists at the base of the snow pack on shaded aspects above an elevation of 9,000 feet. Some potential persists for humans, especially those on snowmachines to trigger dangerous hard slab avalanches to the ground on this weak persistent layer. Previous tracks should not be interpreted as a sign of stability.
