Lo esencial

Several weak layers in the upper snowpack remain reactive, keeping danger considerable

Start with small, low-consequence terrain & test conditions before committing to larger features

    Two persistent weak layers of surface hoar/ facets/ crust from Feb 7th and Jan 26th are buried in the upper meter of the snowpack and remain a significant concern. These layers continue to show reacivity at all elevations.

  • Storm Slabs

    5 to 25 cm of recent snow may be overlying a new surface hoar layer. Recent southwest winds likely built thicker and more reactive slabs on lee slopes below ridgetops. Slabs in motion could step down to deeper persistent layers.

Confidence

Moderate

  • We are uncertain due to a highly variable snowpack.

Avalanche Summary

The reactivity of persistent weak layers is slowly lessening in both size and frequency of triggering.

However, several natural, explosive, skier-triggered and remote-triggered avalanches occurred in the region up to size 3 on Thursday and up to size 2 on Friday. Many of these avalanches failed on, or stepped down to, persistent weak layers. Several also occurred at lower elevations below treeline on relatively benign slopes.

Snowpack Summary

There is a lot of variability in the region, but three prevalent surface hoar layers stand out:

5 to 25 cm of recent storm snow is covering a new layer of surface hoar/ facets or sun crust. This new weak layer may make slabs more reactive and resistant to bonding than usual.

Below that, 20 to 40 cm of older snow is covering a second reactive layer of surface hoar or a crust from Feb 7th.

Lastly, the late January layer of surface hoar/facets/crust is buried 50 to 100 cm deep. This layer continues to surprise people with its reactivity over the past week, especially in sheltered treeline and below treeline features.

The remaining snowpack has no layers of concern

Weather Summary

Partly cloudy. 0 to 4 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -9 °C.

Sunday

Mix of sun and clouds. 20 km/h west ridgetop wind. Treeline temperature -9 °C.

Monday

Mix of sun and clouds. 0 to 5 cm of snow. 30 km/h south ridgetop wind. Treeline temperature -9 °C.

Tuesday

Mostly cloudy. 0 to 4 cm of snow. 10 km/h south ridgetop wind. Treeline temperature -8 °C.

Terrain and Travel Advice

  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.
  • Be especially cautious as you transition into wind-affected terrain.
