Human triggering of wind slabs remains possible.

Continually assess as you travel. Identify wind-affected slopes, and back off if snow feels dense or stiff.

Moderate

• We are uncertain about how quickly persistent slabs are gaining strength.

Reports of avalanche activity has tapered, no new avalanches have been reported this week.

As temperatures are forecast to remain cold temperatures it remains likely that wind slabs will be possible to human trigger as they are slow to bond to hard wind pressed surfaces.

Roughly 15 to 20 cm of new snow was redistributed by moderate southwest wind. This cold new snow overlies previously wind-affected surfaces treeline and above, and at lower elevations a crust.

Two weak layers remain a concern:

• A crust/facet layer buried early February down 90 to 120 cm.

• A surface hoar layer buried mid February down 60 to 90 cm.

Recent avalanche activity has involved these layers with natural and human-triggered avalanches reported.

Below these layers, the remaining snowpack is generally well settled.

• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• If triggered, wind slabs may step down to deeper layers, causing larger avalanches.
• Watch for areas of hard wind slab on alpine features.
• Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
