Regions

Coquihalla, Manning, Skagit.

New snow and wind loading may form reactive storm slabs, especially on north through east facing slopes.

It's a good day to stick to conservative terrain sheltered from the wind.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.
  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

No new avalanches reported. We suspect reactive storm and wind slabs may be seen on Wednesday, especially by the afternoon.

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

Tuesday Night
Mostly cloudy. Up to 5 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -7 °C.

Wednesday
Cloudy. 10 to 20 cm of snow. 70 km/h west ridgetop wind. Treeline temperature -7 °C.

Thursday
Mostly cloudy. 25 to 40 cm of snow. 60 gusting to 115 km/h west ridgetop wind. Treeline temperature -5 °C.

Friday
Mostly cloudy. 5 to 15 cm of snow. 30 gusting to 70 km/h west ridgetop wind. Treeline temperature -5 °C.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Strong wind is building wind slabs farther downslope than usual.
  • Shooting cracks, whumpfs, and recent avalanches are strong indicators of an unstable snowpack.
  • It's a good day to make conservative terrain choices.

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.
