Forecast moderate south winds on Saturday may form reactive wind slabs on lee features.

Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.

Moderate

• We are uncertain about alpine conditions due to limited field observations.

On Thursday, a naturally triggered size 1.5 wind slab was reported on a northeast aspect in the alpine. Observations in this region are very limited.

If you head out into the backcountry, let us know what you're seeing by submitting a MIN report.

Cornices are large and looming. Avoid traveling underneath them.

Forecast moderate south winds may form reactive wind slabs on lee features.

20 to 40 cm of snow overlies heavily wind affected surfaces. Up to 60 cm of snow can be found in sheltered areas.

A persistent weak layer of facets or crust/facets can be found down 65 to 100 cm.

Facets or depth hoar exist at the base of the snowpack, especially in the inland areas that have a shallower snowpack.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
• Use ridges or ribs to avoid areas of wind-loaded snow.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
