Regions

Coquihalla, Harrison-Fraser, Manning, Skagit.

Check how well the recent snow is bonding, and manage your exposure to sun-exposed slopes.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported, but observations are very limited.

Snowpack Summary

Upper elevations may have 10 to 20 cm of recent snow over melt-freeze crusts. A typical spring diurnal pattern is underway: daytime warmth moistens the upper snowpack, while overnight cooling usually forms a hard crust at higher elevations. Lower elevations may not refreeze and are melting out quickly.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Investigate the bond of the recent snow before committing to your line.

Problems

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.
