Kernpunkte

Snow has been falling consistently for a few days.

Assess the area you are in for how that snow has bonded to the old snow, and if the wind has made it more dense or loaded.

    New snow is most likely to be reactive.

    • in wind-loaded leeward terrain features at upper elevations

    • in sheltered areas where it may sit over a weak layer of surface hoar

Confidence

Moderate

  • Uncertainty is due to how quickly the snowpack will recover and gain strength.

Avalanche Summary

Reports of a natural avalanche cycle up to size 2.5 on Monday and Tuesday consisting of storm slabs at upper elevations, with wet loose avalanches at lower elevations.

A few small (size 1) human triggered avalanches were reported on Tuesday, not running far or fast.

Snowpack Summary

up to 50 cm of snow is on the surface in sheltered areas and is wind affected in the alpine and open areas at treeline.

A crust is present at elevations lower than 1300 m and is buried 30cm deep.

A few layers of weak, feathery surface hoar crystals can be found between 50 to 150 cm deep.

Snowpack depths in excess of 300 cm can be found at treeline elevations.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Keep in mind that human triggering may persist as natural avalanches taper off.
  • Make observations and continually assess conditions as you travel.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
