Regions

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

Freezing levels remain elevated tonight and through the day Thursday. Watch for signs of instability increasing as warm temperatures persist especially in areas where solar input is causing rapid change to the snow surface.

Confidence

High

Avalanche Summary

No new avalanches have been reported in this region since Jan 21. Please continue to post your reports and photos to the Mountain Information Network, the information is very helpful to forecasters.

Snowpack Summary

10-20 cm of snow is becoming moist from elevated freezing levels. Below 1300 m moist snow sits above a thin melt-freeze crust. 50 cm of settling snow sits over a hard crust at higher elevations. Below 700 m surface is a hard crust.

The mid and lower snowpack is well-settled and consolidated.

Weather Summary

Wednesday Night

Partly cloudy with clear periods. Northwesterly ridge top winds 15 km/h. 1500m temperature low of 0C. The above-freezing layer remains from 1500 - 2500 m tonight.

Thursday 

Mainly cloudy with isolated flurries, trace accumulation. Moderate northwesterly ridgetop winds occasionally gusting to 50 km/h. 1500m temperature high of 0C. The above freezing layer between 1500 - 2500 m dissipates in the afternoon and freezing levels fall to 1000 m overnight.

Friday 

Mix of sun and cloud. Light westerly ridgetop winds occasionally gusting to 25 km/h. 1500m temperature high of -2C. Freezing levels drop to 800 m. 

Saturday 

Sunny with cloudy periods. Light northeasterly ridgetop winds occasionally gusting to 30 km/h. 1500m temperature high of -5C. Freezing levels drop to 500 m.

Terrain and Travel Advice

  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • Cornices become weak with daytime heating or solar exposure.
  • Stay in tune with the physical environment, conditions may change throughout the day.

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.
