    Slabs may be possible to trigger at high elevations where dry snow has been loaded into leeward terrain features.

Avalanche Summary

There have been no recent avalanche reports in the region.

If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).

Confidence

Moderate

Snowpack Summary

A firm crust may exist at upper elevations. Lower elevations snow surfaces are likely moist and sticky.

North through east-facing slopes in the alpine may have new surface hoar development and hold dryer snow (10 to 20 cm) which sits over moist snow. At treeline, 5 to 10 cm sits above a firm rain crust. Below the crust is a rain-soaked snowpack.

Snow depths at treeline vary across the region from 65 cm to 150 cm.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
