Northeast winds may have created reactive wind slabs in areas where you may not typically see them.

Pay attention as you transition into wind-affected terrain and avoid sunny slopes later in the day.




Avalanche Summary

No new avalanche activity was reported since Friday.

Several rider-triggered size 1 wind slab avalanches were reported on lee aspects at upper elevations on Friday.

If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.

Snowpack Summary

At higher elevations, winds that have switched from the southwest to the northeast may have developed wind slabs on all aspects.

Below the recent snow is a melt-freeze crust, existing on all aspects at treeline and below. The crust extends to mountain tops on sunny aspects. In north-facing high alpine terrain, the surface snow may have remained cold and dry.

The mid and lower snowpack consists of a number of old crusts and facetted snow that continue to be monitored, particularly in shallow snowpack areas.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.
  • Avoid exposure to slopes that have cornices overhead.
