Regions

South Coast, North Shore, Sasquatch, Sky Pilot, Tetrahedron.

Hazard will improve as rain stops and freezing levels lower through the day. Monitor conditions as you move through the terrain.

Watch for unstable snow on specific terrain features, especially where snow is moist or wet.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported however backcountry users should expect to see evidence of a wet loose avalanche cycle from the past 48 hours of rain. Please continue to post your observations and photos to the Mountain Information Network. It helps strengthen our data gathering.

Snowpack Summary

Up to 100 mm of rain in the last 48 hours has saturated the snowpack at all elevations. Previously 25 mm of snow sat upon a melt-freeze crust down 40 cm. The upper snowpack consists of moist snow overlying a few decomposing crusts formed in early January and late December. Generally, the snowpack is well-settled.

Weather Summary

Friday Night

Periods of rain or snow continue, 10 to 20 mm. Winds will ease to southerly 40 km/h. Ridgetop low-temperature +3C. Freezing levels will slowly fall to near 1500 m by Saturday morning.

Saturday

Cloudy with flurries easing in the afternoon, 5-10 mm. Southeast winds of 40 to 60 km/h. Ridgetop high-temperature +7C. Freezing levels will be near 1500 m.

Sunday

Mainly cloudy with scattered flurries, 5-10mm. Light variable winds gusting 20 km/h. Ridgetop high-temperature +6C. Freezing levels 1500 m.

Overnight rain changes to snow, 15-25 mm. Freezing levels will fall to 1000 m by Monday morning.

Monday

Mainly cloudy with isolated flurries, 5 mm. Light variable winds gusting 20 km/h. Ridgetop high-temperature +1C. Freezing levels 1000 m.

Terrain and Travel Advice

  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Loose avalanches may start small but they can grow and push you into dangerous terrain.

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.
