Avalanche Summary
On Monday, a small skier-triggered storm slab was reported on a north aspect in the alpine.
NOTE: Observations are currently very limited.
Snowpack Summary
Up to 20 cm of recent snow may be found at upper elevations. This snow overlies a robust crust everywhere except northerly aspects in the alpine. Westerly wind may have formed wind slabs on lee aspects.
Most terrain has undergone strong melt-freeze cycles, creating a strong, well bonded snowpack.

Terrain and Travel Advice
- Be careful as you transition into wind-affected terrain.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
- Make observations and continually assess conditions as you travel.
