Highlights

Cool and stable weather with no significant precipitation for the next few days will contribute to lower avalanche danger.

Be cautious of surface snow sloughing off steep slopes above you, and enjoy some soft turns in the sun this weekend.

Avalanche problems

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1.5–3

    This problem layer is the crust and facets created by early February's warm spell. It is down 30-90 cm in the snowpack and is a 1-10 cm thick crust or multiple crusts with a layer of weak facets above.

  • Loose Dry

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

    Loose dry avalanches likely won't be much of a hazard unless they push you into or off a terrain trap.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1.5–3.5

    Basal depth hoar makes up the bottom of the snowpack. This is a low probability but high consequence problem. Stay away from weak, rocky, shallow location where triggering this layer is more likely.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
