Points saillants

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

    Probabilité
    Possible
    Taille
    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 19

  • 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

The upper 30 to 40 cm has been redistributed by extreme southerly wind with scoured south facing slopes and loaded, pressed and altered, north facing slopes.

Below 1200 m and on south facing slopes 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.

Wednesday
Mostly sunny. 20 km/h north ridgetop wind. Treeline temperature -9 °C. Freezing level 900 m.

Thursday
Mostly sunny. 20 km/h northeast ridgetop wind. Treeline temperature -12 °C.

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.
