Cooler temperatures will decrease the wet snow avalanche hazard. At the upper elevations, above 9,000 feet, the hazard has increased to moderate. At those higher elevations moderate winds and the new snow will be forming pockets of new soft slab on leeward aspects and will be cross loading gullies. In steep terrain these slabs could be triggered by humans who venture onto them. Today's snow shower activity could be locally intense. Monitor conditions for increasing hazard. Even small slides can sweep riders or skiers into trees and terrain traps. Practice social distancing directives. Conservative terrain choices are warranted given our current health care situation.
At the higher elevations humans could trigger pockets of wind slab formed by southwest to westerly winds. These slabs could be 6 to 18 inches deep and large enough to injure or carry a person long distances on very steep slopes.
( Discussion is generated from the previous day's afternoon forecast. )A large low-pressure system is dropping south along the coastal waters of the Pacific Northwest. As the leading edge of this low moves into Western Wyoming snow shower activity will increase and will continue to favor the southern portions of the Greys River area. Snowfall amounts of 3 to 6 inches are likely down there during the next 24 hours. A weak cold front will pass through the region later tonight. On Wednesday temperatures will be in the single digits and teens in the mountains and rise from the teens into the 30’s in the valleys. Winds will veer to the west at 15 to 25 miles per hour.Cooler temperatures will decrease the wet snow avalanche hazard. Moderate southwest to west winds will continue to form small pockets of wind slab at the upper elevations. Those slabs could be triggered by humans with depths to 18 inches. The general avalanche hazard is expected to be moderate above an elevation of 9,000 feet in the Greys River/Southwest Trails area and between an elevation of 9,000 and 10,500 feet in the Teton area. In those areas the hazard will be low below 9,000 feet . The hazard is expected to be low at all elevations of the Togwotee Pass area.
