Highlights

New snow and wind loading has formed reactive storm slabs.

Make conservative choices and be very wary of exposure to overhead hazards, especially when the sun is out.

Avalanche problems

  • Storm Slabs

    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    1–2

    New snow and strong wind has formed reactive storm slabs. The new snow falls on a variety of surfaces, carefully assess the bond as you travel. The new snow arrives with significant wind, expect deposits to be deeper on north aspects.

  • Loose Wet

    New storm snow is expected to become reactive with solar warming. Watch for natural wet loose avalanches, particularly on sun-exposed slopes.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

On Sunday, the region saw natural and human-triggered avalanches up to size 2.

Natural and human triggered avalanches remain likely on Tuesday.

Snowpack Summary

Up to 60 cm of new storm snow has blanketed the region. This sits on a variety of surfaces, including old wind slab on all aspects, facets, and exposed crust. Expect the potential for a poor bond at the storm snow interface.

The early February crust/facet layer is down approximately 100 cm.

Another widespread crust and facet layer from late January is buried 120 to 160 cm deep.

The mid and lower snowpack is well settled and strong.

Terrain and Travel Advice

  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Shooting cracks, whumpfs, and recent avalanches are strong indicators of an unstable snowpack.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
