Tetons

Rapid snowfall of over a foot of new snow in the past 24 hours with westerly winds have created easily triggered soft slabs to two feet in depth on lee slopes at upper and mid elevations. In steep areas below ridges and in chutes, deeper slides involving older snow could be triggered by backcountry travelers. Be alert as the hazard will increase with forecasted continuing snowfall. Cautious route-finding and conservative decision-making will be essential today. At lower elevations be alert to loose sloughs on isolated, steep terrain features.

Light snow is expected through Monday. Temperatures at 9500 feet will cool to the low teens overnight then warm to the mid 20s. Ridge top winds will be southerly at 10 miles per hour.Backcountry travelers will be able to easily start sloughs or soft slabs to 18 inches in depth on steep slopes at upper elevations in the Tetons where the hazard is expected to be Moderate. Triggered slides will rapidly entrain debris and build to dangerous volumes. Similar conditions will prevail in the Greys River and Togwotee Pass areas. The potential also remains for users to trigger slides that pull out older, deeper slabs to three feet in depth on very steep slopes and chutes below ridge crests. At mid and lower elevations people could trigger loose sloughs in very steep areas.
