Highlights

Rapid loading or rapid heating will cause stability to deteriorate quickly.  Pay lots of attention to the aspect you are traveling on.

Avalanche problems

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2
    Loose wet point release avalanches are occurring on solar aspects related to daytime warming.  In some areas these smaller avalanches are triggering slabs on underlying slopes.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    2–6
      The basal facets are producing large slab avalanches that are failing on the basal facets.

Confidence

Fair - Timing, track, or intensity of incoming weather system is uncertain on Friday

Weather Forecast

Avalanche Summary

Sporadic natural avalanche activity up to sz 3 continues in all three elevation zones.  The majority of these slides that are occurring are related to daytime heating.

Snowpack Summary

Spring conditions. The snowpack is settling rapidly. Surface crusts are melting during the day and re-freezing at night. The snowpack has gone isothermal at lower elevations on the warmer days. Even North aspects have been affected with moist snow as high as 2500m. Where cornices exist they are large and sagging.
