Regions

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

Freezing levels should drop enough for some new snow to fall in the alpine and possibly at treeline. Expect any fresh accumulations to become unstable when the pendulum swings back to rain.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported. Observations are limited in this area, but so is the snowpack.

If you head out into the backcountry, please consider sharing your observations on the MIN.

Snowpack Summary

A mix of snow followed by heavy rain will do little to improve snowpack coverage by end of day Tuesday. High alpine locations may see 10 -15 cm accumulate before it is again affected by rain.

Before the storm, higher treeline areas held an estimated 20 to 50 cm of snow. This diminishes rapidly below 1500 m.

Weather Summary

Monday Night
Cloudy with light flurries bringing 4 to 10 cm of new snow. 40 - 60 km/h southwest ridgetop wind. Treeline temperature 0 to -1 °C. Freezing level 1100 - 1300 m.

Tuesday
Cloudy. 20 to 30 mm of precipitation, first as snow, increasingly as rain at treeline. More snow again overnight. 20 - 60 km/h south ridgetop wind. Treeline temperature -1 to 1 °C. Freezing level 1300 - 1600 m.

Wednesday
Mostly cloudy with scattered flurries after 20 to 30 cm of snow overnight. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.

Thursday
Cloudy with 20 to 50 cm of new snow, including overnight amounts, rain during midday. 60 km/h south ridgetop wind. Treeline temperature -3 °C to 1 °C. Freezing level rising to 1500 m before returning to 1100 m.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Watch for rapidly changing conditions during periods of heavy loading from new snow, wind, or rain.

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.
