Deep persistent slabs remain a problem on steep slopes. These slabs could be triggered by the weight of a single person. Conservative terrain choices are essential for safe travel in avalanche terrain today.
Very large dense slab avalanches up to six feet in depth are likely to be human triggered on steep slopes that are underlain by a base of week faceted snow. These slabs clound be triggered by the first person on a slope or after a slope has been crossed multiple times.
( Discussion is generated from the previous day's afternoon forecast. )Some light snow will move back into the region from the Pacific Northwest overnight. Accumulations of one to three inches are likely at the higher elevations by daybreak. On Tuesday this snowfall is expected to increase in coverage and intensity with another three to six inches of accumulation possible. Winds will back towards the southwest at speeds of 10 to 20 miles per hour. Temperatures will be in the teens overnight and rise into the 20s during the day.The general avalanche hazard is expected to remain CONSIDERABLE in the Greys River/Southwest Trails and the Togwotee Pass/Continental Divide areas. In the Teton area the general avakanche hazard is expected to be CONSIDERABLE at the upper elevations and be MODERATE at the mid and lower elevations. Slab avalanches with depths of two to six feet are likely to be human triggered in the Greys River/Southwest Trails and the Togwotee Pass/Continental Divide areas. In the Teton area slabs with depths of 1 to 3 feet could be human triggered in steep, wind loaded avalanche starting zones.
