  Rain on snow and warm temperatures should have prevented much of a refreeze last night meaning that wet snow remains widespread across all aspects below 8500 ft. Human triggered loose wet avalanche activity will remain possible on slopes 35 degrees and steeper on all aspects below 8500 ft. Some natural loose wet avalanche activity could also occur. Most of these wet snow instabilities should remain limited to roller balls, pinwheels, and small wet snow sluffs, but some of them could entrain enough snow to cause problems for backcountry travelers. Wet slab avalanche activity should remain unlikely but isolated wet slabs are not impossible today.

  Above 8500 ft. new snow and strong winds could have formed new winds slabs on the leeward NW-N-NE-E-SE aspects in near and above treeline terrain. These wind slabs should remain small due to the small amounts of new snow received overnight but could reach up to 1 ft. in depth in some areas. Human triggering of these wind slabs will be possible today.
