Regions

Yukon, Tutshi, Wheaton, White Pass East, White Pass West.

Wet loose avalanches may occur on steep sun exposed slopes during the heat of the day.

Cornices are large and may weaken with daytime warming.

Confidence

High

Avalanche Summary

No new avalanches were reported in this region on Thursday.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

Predominantly wind affected snow surfaces are found in the alpine. Wind-sheltered terrain may hold settled soft snow that can produce dry loose avalanches with skier traffic in steep terrain. Steep sun-exposed slopes will moisten with daytime warming and freeze into a hard melt-freeze crust overnight.

Cornices are large and looming at this time of year.

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.
  • Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.
  • Make observations and assess conditions continually as you travel.

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.
