Carefully assess conditions as you gain elevation. Where precipitation fell as snow, storm slabs are possible.
At low elevations, you'll find a wet and compacted snowpack.

Avalanche Summary
No recent avalanches have been reported in this region.
If you do head into the backcountry please consider submitting observations and/or photos on the Mountain Information Network.
Snowpack Summary
Light, mixed precipitation continues. In terrain where more than 20 cm of storm snow has accumulated, small storm slabs may avalanche under the weight of a human. At treeline and below precipitation is likely to fall as rain, keeping the snow surface moist.
The mid and lower snowpack is made up of a series of crusts and rounded grains. The snowpack is generally well consolidated.
Overall, the snow depth remains shallow, creating challenging travel conditions and hiding early season hazards just below the snow surface.

Terrain and Travel Advice
- Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
- Be cautious of buried obstacles especially below treeline.
