Tetons

Deep snow from the weekend storm rests on slick sun crusts and firm wind-pack at mid and upper elevations. Backcountry travelers could trigger soft slabs or sloughs to 18 inches in depth on very steep slopes. Debris from these slides have been building rapidly to dangerous size. At upper elevations, deeper slides involving older snow could be triggered in very steep areas below ridges and in chutes. At low elevations be alert to pockets of loose sloughs on isolated, steep terrain features.

LIght snow is expected overnight into Wednesday morning with up to three inches of accumulation in the Tetons and Togwotee Pass areas and one to two inches in the Greys River mountains. Morning temperatures at 9500 feet will be in the low teens then warm to near 30 degrees during the day. Ridge top winds will continue strong through the period from the west with 25 mile per hour averages and stronger gusts.The avalanche hazard is expected to be Moderate Wednesday. Ample available snow and very strong winds will increase both the size and sensitivity of slabs on lee slopes. Backcountry travelers will have the potential to release slabs to three feet in depth on lee slopes at upper elevations.
