Tetons

Surface slabs to eighteen inches deep could be human triggered today in steep wind loaded terrain at the high elevations. The remote possibility also continues to trigger deep hard slabs in cliff areas at the mid and high elevations. Avalanches at low elevations are unlikely except for isolated pockets in paths prone to excessive wind loading.

An upper level disturbance moving northeast across Nevada will bring clouds and some light snow showers to the area. Accumulations of 1 to 3 inches are possible by Friday night. Mountain temperatures will rise into the teens from overnight lows in the single digits above zero. Colder overnight temperatures are likely in the valleys. Ridge crests winds will be southwesterly at 20 to 25 miles per hour. The general avalanche hazard in the Teton Area is expected to be LOW. Mostly stable snow exists, however isolated pockets of slab one to three feet in depth could be human triggered in steep avalanche starting zones and in cliff areas. The general avalanche hazard in the Togwotee Pass/Continental Divide Trails Area is expected to be MODERATE. Slab avalanches could be human triggered on steep slopes that are underlain by weak faceted snow and have potential to step to the ground.The general avalanche hazard in the Greys River/Southwest Trails Area is expected to be CONSIDERABLE. In steep terrain dangerous slabs lie upon a base of weak faceted snow and could be triggered by humans who venture onto them.
