Highlights

A winter interlude in the middle of spring has us thinking about winter problems again. Watch for windslabs in alpine and treeline lees.

Be prepared to travel in spring conditions again later this week.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    1–1.5

    New snow and strong SW winds are forming wind slabs in immediately and ridge crests. Slabs sit top refrozen surfaces and may well not bond

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    1–1.5

    As temps warm throughout the week we expect to see new snow transition to a wet loose.
