Strong southwest wind may form slabs on lee features at treeline and above.

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

Moderate

• We are uncertain about forecast snowfall amounts.

No recent avalanches have been reported.

15 to 25 cm of new snow and strong southwest wind may form wind slabs at treeline and above. The recent snow overlies a persistent weak layer.

At treeline and above, this layer is primarily a hard crust with weak facets above and/or below.

In sheltered treeline locations and below, this layer may be a combination of hard crust and/or surface hoar.

The mid/lower snowpack is generally well settled and strong.

Snowpack depth ranges between 100 to 250 cm at treeline elevations.

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