Kernpunkte

Abundant sunshine and warming temperatures will be increasing the hazard as the day progresses. Todays 5 AM temperatures are ten degrees warmer than yesterdays. Surface slabs up to two feet in depth could be human triggered at the higher elevations and may release naturally during the heat of the day. Wet loose slides are likely in steep terrain. Cornice failures are possible. Monitor conditions and plan to avoid avalanche terrain after snow surfaces have significantly softened.

Lawinenprobleme

  • Wet Slabs

    Wahrscheinlichkeit
    Likely
    Größe
    1–2

    Wet surface slabs up to two feet in depth are likely to occur on steep slopes after significant warming has occurred. These slabs were formed by northwest winds and will be dry at the higher elevations in the early morning hours and become damp during the course of the day. These slabs could be human triggered in the morning and could release naturally during the warmest portion of the day.

  • Loose Wet

    Wahrscheinlichkeit
    Likely
    Größe
    1–2

    Abundant sunshine and warming temperatures are likely to cause wet loose slides on very steep slopes on a variety of aspects and elevations. At the upper elevations these loose snow slides could trigger wet slab avalanches.

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    2–3

    Huge cornices exist. Cornice failures are possible today. Large cornice drops could trigger very large, deep slab avalanches.

Avalanche Discussion

Conditions will remain dry and unseasonably warm overnight and into the afternoon on Wednesday, before clouds begin to increase as a weak cold front passes to the north and east. Mostly clear skies tonight will allow air temperatures to drop into the upper 20s to low 30s. Snow surfaces are expected to freeze by daybreak but soften during the morning hours. Temperatures on Wednesday will once again rise into the 40s and 50s in the mountains. Southwest winds will veer towards the west and increase from 15 to 25 miles per hour with higher gusts ahead of the approaching front. Scattered mountain rain and snow showers are possible during the late afternoon and early evening hours in the Teton Range and along the Continental Divide. The general avalanche hazard is expected to be mostly low in the early morning hours and increase to CONSIDERABLE at the higher elevations after snow surfaces soften. Wet slabs up to two feet in depth and shallow wet loose slides are likely in steep terrain. Cornice failures are possible and have some potential to trigger large, deep wet slab avalanches in isolated areas.
