The general avalanche hazard is MODERATE today above an elevation of 7,500 feet and will be increasing as the day progresses. Human triggered avalanches are possible on a variety of aspects at the mid and upper elevations. Avalanches are unlikely at the lower elevations where the hazard will be LOW.
Winds that veered from the southwest to the northeast and then back to the west have transported recent snow into surface slabs on a variety of aspects. Slab avalanches, one to three feet in depth, could be human triggered today in steep terrain.
( Discussion is generated from the previous day's afternoon forecast. )A low pressure trough will track across Wyoming from the Pacific Northwest into the Central Plains. This system will bring moisture to the region through Sunday night and will be followed by an arctic cold front. Cold, light density snowfall is expected overnight and through the day on Sunday. Accumulations of a foot or more of new snow are likely by Monday morning. Temperatures will remain in the single digits. Winds will be west-southwest at 15 to 20 with gusts to 30 miles per hour.Slab avalanches with depths of one to three feet could be human triggered in steep terrain at the mid and upper elevations. Avalanches are unlikely at the lower elevations. With new snow in the forecast the general avalanche hazard is expected to be CONSIDERABLE at the upper elevations, MODERATE at the mid elevations and LOW below an elevations of 7,500 feet.
