Choose conservative terrain in the alpine and give the storm snow time to bond. Storm slabs will be most reactive on high north facing terrain.

Summary

Confidence

Moderate

Avalanche Summary

On Wednesday a skier triggered a size 1 wind slab on a north facing roll in the alpine.

Snowpack Summary

20 to 50 cm of recent storm  snow has been redistributed into wind slabs by southerly winds. This snow overlies a thick crust on all aspects and at all elevations. At lower elevations moist snow is likely found.

The mid and lower snowpack consists of various old crusts and is generally well-settled and well-bonded.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
