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

Thin wind slabs may be found on lee features at uppermost elevations.

Closely monitor how the new snow is bonding to the old surface.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported. Recent wet snow and rain may have caused wet loose avalanches in steep terrain, but field observations are limited.

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

Snowpack Summary

10-15 cm of fresh snow may be found over a recent melt-freeze 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, the snow depth remains shallow between 70 and 100 cm, and early-season hazards are prevalent at 1400 m and below.

Weather Summary

Sunday Night

Partly cloudy, no precipitation, alpine wind southwest 20 km/h, treeline temperature around -2 °C, freezing level at 1000 m.

Monday

Mainly sunny, no precipitation, alpine wind southwest 20 to 30 km/h, treeline temperature -1 °C, freezing level at 1300 m.

Tuesday

Mix of sun and clouds, no precipitation, alpine wind south 30 to 50 km/h, treeline temperature around +1 °C, freezing level at 1400 m.

Wednesday

Mostly cloudy, no precipitation, alpine wind south 20 km/h, treeline temperature around +1 °C, freezing level at 1500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Investigate the bond of the recent snow
  • 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.
