Tetons

New snow is falling on a mostly stable snowpack that is capped with hard snow surfaces. This new snow could be triggered by backcountry skiers and riders today as soft surface slabs or as loose snow sluffs in steep avalanche terrrain. Although small in size these events could quickly entrain enough snow to carry or knock people over in extreme terrain such as cliff areas and couloirs. This hazard will increase at the mid and upper elevations today as new snow and northwest winds continue and slabs of six inches to a foot could develop and be triggered this afternoon.

Some additional light snowfall is likely overnight. Snow shower activity will end on Sunday. Skies will slowly clear as a high pressure ridge builds into the region. Temperatures will be cold in a northeast flow. Overnight lows near zero are expected. Daytime highs will rise into the single digits and teens. Winds will be easterly at 10 to 20 miles per hour with higher gusts.At the mid and upper elevations small pockets of soft surface slab up to 18 inches in depth in isolated areas could be triggered by skiers or riders in steep avalanche starting zones and cliff areas. Shallow loose snow sluffs could also be human triggered on very steep slopes. The general avalanche hazard is expected to be MODERATE above an elevation of 8,000 feet and LOW below that elevation.
