Regions

Coquihalla, Manning, Skagit.

New snow and wind loading has formed reactive storm slabs.

Make conservative choices and be very wary of exposure to overhead hazards, especially when the sun is out.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

A few natural wind slabs were observed in steep, north facing terrain on Sunday. No other recent avalanches have been observed.

Natural and human triggered avalanches remain likely on Tuesday.

Snowpack Summary

Up to 25 cm of new snow overlies a mix of facets, exposed crusts, and sun-affected snow. Leeward aspects (north to northeast) may hold deeper and stiffer storm slabs due to wind loading during the storm.

A widespread crust/facet layer from late January is buried 60 to 90 cm deep.

The mid and lower snowpack is generally well settled and strong.

Weather Summary

Monday Night
Partly cloudy. 20 km/h northwest ridgetop wind. Treeline temperature -7 °C.

Tuesday
Sunny. 10 km/h south ridgetop wind. Treeline temperature -5 °C.

Wednesday
Mostly cloudy. 5 to 15 cm of snow. 60 km/h west ridgetop wind. Treeline temperature -6 °C.

Thursday
Mostly cloudy. 10 to 30 cm of snow. 90 km/h southwest ridgetop wind. Treeline temperature -5 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • Shooting cracks, whumpfs, and recent avalanches are strong indicators of an unstable snowpack.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
