Kernpunkte

A strong storm will create very dangerous conditions where the wind drifts deep slabs of snow. Travel in avalanche terrain is not recommended at middle and upper elevations. Large, natural avalanches could easily be big enough to bury or kill you. Stick to low-angle, wind-sheltered terrain far away from steep overhead slopes.

    If you travel in the backcountry, be sure of your ability to avoid avalanche terrain and slopes steeper than 35 degrees. Stay well away from steep slopes on leeward sides of ridges and below cliffs.  The wind will form deeper drifts and larger, more dangerous avalanches. Seek out lower-angle, wind-sheltered terrain. Watch for cracks shooting through the snow and recent avalanches to indicate the danger.

    Even on sheltered slopes, you could trigger avalanches 1-1.5 feet deep in the new and recent snow. Use small features and quick tests to see how easily the snow slides before getting onto slopes that are steep enough to ski or ride down.

Avalanche Discussion

An intense and prolonged storm moved into the region on Wednesday and will run at least into Thursday night. Expect around 1.5 feet of new snow. Winds will increase throughout the day becoming strong and driving intense blowing snow.

On Tuesday and Wednesday, observers on Delancey Ridge reported triggering small avalanches and other signs of instability in wind-drifted snow. There was 6" of new snow at the Silver Star trailhead.

The snowpack in the eastern portion of the zone is shallower and may hold more weak layers. Pay attention to red flag signs of instability, such as whumping collapses, and consider digging down to identify and layers of weak snow. Last week, observers reported small avalanches failing on a layer of buried surface hoar. The distribution of the surface hoar is uncertain, though it could exist in other areas of the eastern mountains and foothills.
