Rapidly warming temperatures and sunshine will soften snow crusts and increase the avalanche hazard. Wet loose and wet slab avalanches are possible after significant warming occurs. Avalanche terrain should be avoided after snow surfaces soften.
Wet loose slides are possible after snow surfaces have softened and could pull out deeper layers or run to the ground on steep slopes where the snow is wet, loose and unconsolidated.
Dangerous wet slab avalanches are possible in steep avalanche paths during the heat of the day. These slabs could be triggered by snow machines and are likely to fail on buried layers of faceted snow or the ground. Avalanche terrain should be avoided once surfaces soften.
( Discussion is generated from the previous day's afternoon forecast. )High pressure will keep skies mostly clear Saturday night through Monday. Clear nights will allow good cooling with mountain lows dropping to 20 degrees Sunday morning. Temperatures will warm rapidly with sunrise and highs will reach into the upper 30s or warmer. Winds at 10,000 feet will be westerly at 10 miles per hour.Crusts will form overnight on most slopes for good morning stability. Rapid warming with the sun will increase the chance of triggering wet-loose slides in the Tetons and possibly deeper slabs in the Togwotee Pass and Greys River areas. The General Avalanche Hazard will be LOW in the Morning then rise to MODERATE when crusts break down.
