Highlights

As the surface crust becomes wet and slushy over the day, wet loose avalanches may be possible. Particularly in steep, sun-facing terrain.

Avalanche problems

  • Loose Wet

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

    Wet loose activity is most likely on steep south-facing aspects, once the sun and warming deteriorate the surface crust.

Confidence

High

  • Confidence is due to a stable weather pattern with little change expected.

Avalanche Summary

No new avalanche activity has been reported since the most recent storm cycle ended on Tuesday. A thick surface crust is widespread across most elevations and aspects. As daytime warming weakens the crust, wet loose avalanches may become possible.

Cornices are large following the recent storm. Keep them in mind as the tropical weather persists; cornice failures could act as large triggers for slopes below.

Snowpack Summary

A thick surface crust extends to mountain top on all aspects and elevations. Save for dense trees below treeline, where a crust may not have formed, and the snowpack is moist. Underneath the crust, the storm snow from last weekend is drying out and well settled.

The mid and lower snowpack is well consolidated, consisting of multiple crusts and rounded grains. There are no layers of concern at this time.

Terrain and Travel Advice

  • Avalanche danger will increase as the surface crust breaks down.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
