North Columbia

Riders may still trigger wind slabs in the alpine.

Periods of low danger can be a good time to check out larger objectives.

On Tuesday, there was a natural wet loose avalanche cycle in the recent snow, mostly small but some up to size 2.

On Monday, several skier-triggered size 1 wind slabs were reported on northerly aspects below ridge tops.

NOTE: Observations are currently very limited.

Up to 25 cm of recent snow may be found at upper elevations. This snow overlies a robust crust everywhere except northerly aspects in the alpine.

Most terrain has undergone strong melt-freeze cycles, but the snowpack remains slightly more complex on north-facing alpine slopes, where buried weak layers may still be present.

• Carefully evaluate steep lines for wind slabs.
• 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.
