Wet loose avalanches are possible on steep sun-exposed slopes. Give cornices a wide berth from above and below.
Where a thick surface crust exists avalanche activity will be unlikely.

Avalanche Summary
No recent avalanche reports by 4 pm on Wednesday. Sunshine and rising temperatures may weaken the surface snow and initiate small wet loose avalanches on southerly-facing slopes. Use caution on north-facing slopes in the alpine as they may host pockets of wind slab.
If you head into the backcountry, please submit any observations or photos to the Mountain Information Network.
Snowpack Summary
Up to 20 cm of new snow overlies the old snow surfaces, but may only exist on high north slopes after Wednesday's sunshine. The new snow sits above a widespread crust at all elevations besides the high north-facing slopes where small pockets of wind-affected dry snow exist.
Watch for moist, unstable snow on southerly slopes with sun and warm temperatures.
Below treeline elevations have minimal snow cover. Expect challenging travel conditions with hazards like rocks, stumps and open creeks.

Terrain and Travel Advice

- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
Problems
