Lingering snow in gulleys and northernly features will continue to cycle through diurnal swings in temperature, increasing the hazard through the day.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–2
    Spring weather can often bring variable amounts of precipitation, localized winds, and rapid loading in alpine lee features.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Very Likely
    Size
    1–2.5
    Expect these avalanches to start early on all slopes where the seasonal snow persists.

  • Wet Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely - Very Likely
    Size
    1.5–3.5
    Warm temperatures, solar radiation, and cornices falling; one, or a combination of these are acting as triggers and creating large destructive avalanches.

Snowpack Summary

Snow still sticking around at treeline elevations and above on northerly slopes. Deep persistent slabs are out on most aspects in the alpine and treeline. Large triggers, like cornices still lingering in many alpine areas. Isolated spring storms may create non persistent instabilities, like wind slabs, and sluffing.

Avalanche Summary

Large destructive avalanche are running from all elevations and aspects!
