Highlights

Rising temperatures will keep the danger elevated.

There is uncertainty around how the continued warmth will affect the snowpack.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    1.5–2.5

    Extreme wind has redistributed recent storm snow, forming deep deposits in lee and cross-loaded terrain features at all elevations. Treat the snowpack as suspect anywhere the snow surface isn't scoured.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    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 rapidly fluctuating freezing levels.
  • Uncertainty is due to limitations in the field data.

Avalanche Summary

January 16 & 17

  • No new avalanches report 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. The wind 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.

Monday
Mix of sun and clouds. 20 km/h northwest ridgetop wind. Treeline temperature -4 °C.

Tuesday
Mostly sunny. 20 km/h east ridgetop wind. Treeline temperature -8 °C. An above freezing layer between 1500 m and 2400 m.

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.
