Tetons

The general avalanche hazard at mid and upper elevations is MODERATE this morning increasing to CONSIDERABLE at upper elevations this afternoon/evening. Yesterday and overnight new light density snow was bonding poorly to the old crusts and was being drifted into lee areas at 8500 feet and above. Slabs to 18 inches in depth exist on lee slopes at upper elevations and could be easily triggered by backcountry travellers today. Due to the thin snowpack injuries from contact with surface objects could be serious even if caught in a small slide. The general avalanche hazard is LOW at low elevations

Snowfall is expected to become more widespread throughout the western mountains tonight with another 3 to 6 inches falling at the upper elevations and 1-3 inches falling at the lower elevations. Morning snow showers will taper to scattered snow showers in the afternoon and clearing skies by Monday night. Overnight lows will be in the teens to 20s, daytime highs will rise into the 20s to low 30s. West winds will increase to 25 to 35 MPH with higher gusts. AVALANCHE HAZARD FOR THE TETON, TOGWOTEE PASS/CONTINENTAL DIVIDE AND GREYS RIVER/SOUTHWEST TRAILS AREASThe general avalanche hazard for Monday is expected to be CONSIDERABLE at the upper elevations (10,500 to 9,000 feet), MODERATE at the mid elevations (9,000 to 7,500 feet) and LOW below 7,500 feet. Strong winds will continue to form new soft slabs on leeward aspects at the mid and upper elevations. Slabs depths to two feet are possible. These slabs are likely to be easily triggered by humans and may release naturally in heavily loaded starting zones. At the lower elevations new snow slabs are expected be isolated and shallow.
