Points saillants

Air temperatures dropped to around freezing overnight after a very warm day. Snow surfaces will soften early and create dangerous conditions. Wet slides will continue to be a problem on steep slopes. Loose wet slides, wet slab avalanches and cornice drops are possible. Avoid steep slopes and their run-out zones after snow surfaces have softened.

Problèmes avalancheux

  • Wet Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    2

    Dangerous wet slabs up to three feet in depth will become increasingly sensitive to human triggers and natural release as the day warms.

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1

    Wet loose slides are possible on a variety of steep slopes after significant warming occurs. These slides could dig down to lower layers and trigger underlying wet slab avalanches.

  • Cornices

    Cornice failures are possible. Large cornice drops could trigger dangerous wet slabs.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )The high pressure ridge over the western states will shift slowly east with a southwest flow developing through the day. Expect increasing clouds with a chance of some light snow showers in the mountains and light rain showers in the valley by evening. Temperatures will drop into the upper 20s overnight and rise into the 30s and 40s during the day. Winds will be west to southwest at 10 to 30 miles per hour.If skies clear overnight and temperatures drop below freezing the general avalanche hazard is anticipated to be LOW in the early morning hours and rise to MODERATE as temperatures increase. Wet slides are possible on steep slopes snow surfaces have soften.
