Tetons

Backcountry skiers or riders could trigger pockets of surface slab to eighteen inches in depth in steep avalanche terrain today. These small slabs are most likely to be found in and around cliff areas. There is a chance of wet-loose surface slides on sunlit slopes at all elvations if sustained sunshine melts existing strong sun crusts.

Clouds will increase overnight ahead of a strong Pacific front. Light snow will begin Saturday morning then become heavy in the afternoon and early evening. Snow depths of six to twelve inches are forecasted in the Tetons by late Saturday night. Winds will continue from the southwest and increase to thirty miles per hour with strong gusts. Temperatures will remain in the mid twenties Saturday morning to night. Temperatures on the valley floor will rise to the upper thirties bringing a chance for rain. The Greys River area peaks are forecasted to receive up to six inches of snow and the Togwotee Pass area four inches.Cooling temperatures Friday night will allow strong sun crusts to re freeze. The general avalanche hazard is expected to be Low in the Tetons and Togwotee Pass areas and Moderate in Greys River region Saturday morning then increase rapidly to Moderate and possibly Considerable by Saturday night with heavy new snow and wind. Faceted snow on shaded aspects and smooth sun crusts on southerly aspects will create unstable conditions and make avalanches easy to trigger. At low elevations any rain will make wet-loose slides probable on road cuts or ravines.
