Regions

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

Freezing levels reach well into the alpine Wednesday and Thursday causing surface snow to slowly deteriorate. A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.

Confidence

Moderate

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.

Snowpack Summary

10-20 cm of storm snow from the weekend is found in wind-sheltered terrain features. In some areas, new snow sits on top of 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.

Last week's rain saturated the snowpack and created a well-consolidated lower snowpack.

Weather Summary

Tuesday Night 

Cloudy with isolated flurries stopping early evening, trace accumulation. Westerly ridge top winds 15-20 km/h. 1500m temperature low of -1C.

An above freezing layer develops from 1500 - 2500 m by morning. 

Wednesday 

Mainly sunny with low valley cloud. Light westerly ridgetop winds gusting to 25 km/h. 1500m temperature high of +3C. Freezing levels continue to rise to 3000 m. 

The above freezing layer remains from 1500-2500 m overnight. 

Thursday 

Cloudy with sunny periods and isolated flurries, trace accumulation. Light westerly ridgetop winds occasionally gusting to 40 km/h. 1500m temperature high of 0C. An above freezing layer remains between 1500-2500m. 

Friday 

Mix of sun and cloud. Light westerly ridgetop winds occasionally gusting to 35 km/h. 1500m temperature high of -1C. Freezing levels drop to 800 m.

Terrain and Travel Advice

  • Be especially cautious as you transition into wind affected terrain.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet

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.
