Regions: Coquihalla, Harrison-Fraser, Manning, Sasquatch, Skagit, Stave.

Spring like weather may raise avalanche danger on specific terrain features. Watch for wet snow on steep, sun affected slopes.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported in the region.

If you do head into the backcountry please submit any observations and/or photos on the Mountain Information Network.

Snowpack Summary

Warm temperatures and sun may moisten the surface snow and break down crusts likely formed overnight. A widespread layer of breakable crust with surface hoar is buried around 5-10 cm deep, under wind affected snow.

The mid and lower snowpack is made up of a series of crusts and rounded grains. The snowpack is generally well consolidated.

Overall, the snow depth remains shallow, hiding early season hazards just below the snow surface.

Weather Summary

Saturday Night

Mostly clear skies with no snowfall. Freezing levels remain above 2000 m. Southwest winds continue, 40-60 km/h.

Sunday

Sunny with no snowfall. Freezing levels spike to 3000 m, treeline temperatures reach +5 °C. Winds ease from the southwest, 20-30km/h.

Monday

Partly cloudy. Freezing levels remain above 2500 m, treeline temperatures around +3 °C. Southwest winds continue, 30-40km/h.

Tuesday

Mostly cloudy. Freezing levels fall to 1500 m gradually, treeline temperatures around +3 °C. Southwest winds, 20-30 km/h in the morning build over the day.

Terrain and Travel Advice

  • Avoid sun exposed slopes, especially if snow surface is moist or wet.
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.

Avalanche Problems

Loose Wet

Wet avalanches will be most likely where warm temperatures are combined with sun on south facing slopes. Buried crusts and surface hoar create ideal sliding surfaces for avalanche activity.

Aspects: South East, South, South West.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5
