Lo esencial

Cooler weather will consolidate the upper snowpack.

Be cautious in thin snowpack or rocky areas where triggering a deeper layer may be possible.

Problemas de aludes

  • Wind Slabs

    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely
    Tamaño
    1.5–2.5

    Old and hard windslabs may be lingering in lee and cross-loaded terrain features at all elevations.

  • Persistent Slabs

    Possible
    Tamaño
    2–3.5

    A weak layer of facets may be found 70 to 100 cm deep. In shallower inland areas, weak depth hoar exists to ground.

    Warm temperatures in the alpine may increase the sensitivity of this layer.

Confidence

Moderate

  • Uncertainty is due to limitations in the field data.

Avalanche Summary

January 16 to 18

  • No new avalanches reported but observations are limited. Consider posting to the MIN if you are out in the mountains!

January 15

  • Large natural avalanches (size 3) where reported and may have been a day old.

  • A small (size 1) persistent slab was remotely triggered near log cabin.

January 14

  • A large (up to size 3.5) natural avalanche cycle occurred during periods of rapid loading and warming. Breaking mature timber and going through lake ice at Bryant lake.

Snowpack Summary

30 to 40 cm of snow has accumulated over the past week and has been redistributed by extreme southerly wind with scoured south facing slopes and loaded north facing slopes.

At lower elevations a crust is present on or under the recent snow.

A weak layer of facets is buried 70 to 100 cm deep. In shallow snowpack areas, the bottom half of the snowpack is composed of weak depth hoar.

Terrain and Travel Advice

  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
