Regions

Sasquatch, Sasquatch, Coquihalla, Harrison-Fraser, Manning, Skagit.

Thin wind slabs may be found on lee features in the alpine.

Before committing to your line, consider the consequence of any fall. Barely buried early season hazards remain.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported.

If you head into the backcountry by any method of travel, please consider submitting observations and/or photos on the Mountain Information Network.

Snowpack Summary

Freezing levels vary widely across this forecast area, so expect a mix of wet snow, frozen crusts, and dry snow on the surface, depending on elevation.

In general: 10-15 cm of settling snow may be found over a frozen crust, which overlies 15-25 cm of moist snow. This shows a good bond to the well-settled snowpack, containing several melt-freeze crusts.

Overall, treeline snowpack depths are shallow, between 70 and 120 cm, and early-season hazards are prevalent at 1400 m and below.

Weather Summary

Wednesday Night

Cloudy. 3-7 cm of snow above 1000 m. Light to moderate southwest ridgetop wind. Treeline low around -4 °C.

Thursday

Cloudy. 2-5 cm of snow expected above 800 m. Moderate southwest ridgetop wind. Treeline temperature around -4 °C.

Friday

Mostly cloudy. 5-10 cm of snow expected above 750 m. Moderate to strong southwest ridgetop wind. Treeline temperature around -6 °C.

Saturday

Mostly cloudy. 10-15 cm of snow expected above 300 m. Moderate southwest through northwest wind. Treeline temperature around -7 °C.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
