Avalanche Summary

We haven't received any reports of recent avalanche activity.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

Around 5 to 10 cm of soft snow overlies a hard melt-freeze crust above 1200 m on northerly aspects. The crust is on the surface on sun-exposed slopes and below 1200 m. The crust will transition to moist snow with daytime warming and freeze back into a crust overnight.

Cornices are large and looming at this time of year.

Weather Summary

Wednesday Night

Clear skies. 10 km/h northwest ridgetop wind. Treeline temperature 0 °C.

Friday

Sunny. 10 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 1600 m.

Saturday

Sunny. 10 km/h southeast ridgetop wind. Treeline temperature 3 °C. Freezing level 1600 m.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

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.
