Tetons

At the mid and upper elevations strong southwest winds will drift snow onto existing slabs. This loading will increase the potential for humans to trigger soft surface slabs up to three feet deep in steep wind loaded avalanche starting zones and cliff areas. Some potential remains for humans, especially those on snow machines, to trigger hard slabs up to five feet deep. Avalanches are unlikely at the lower elevations.

The National Weather Service in Riverton has issued a winter storm warning and the Pocatello office has issued a Blizzard Warning. Heavy snow and strong winds will continue to create whiteout conditions and are likely to cause temporary road closures. Up to 14 inches of additional snow is expected in the mountains. Temperatures at 10,000 feet will be in the single digits. Ridge crest winds are forecast to be southwesterly at 50 with gusts to 70 miles per hour. The general avalanche hazard is expected to be HIGH. Human triggered and naturally released slab avalanches are likely. New soft slabs up to three feet in depth could step down to deeper persistent weak layers of faceted snow.
