Avalanche Summary

There have been no recent avalanche reports in the region.

Increasing snowfall mixed with rain and strong southwest wind are certain to induce a natural avalanche cycle.

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

Snowpack Summary

New snow mixed with rain will bury a firm crust at treeline and will become increasingly unstable as the new snow rapidly gets deeper. North through east-facing slopes in the alpine may have buried surface hoar which sits over moist snow.

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

Weather Summary

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avalanche danger will rapidly increase if snow switches to rain.
