A surface crust will create challenging travel conditions.

If dry snow exists in the alpine, watch for pockets of wind slab in lee terrain features.

• Watch for areas of hard wind slab on alpine features.
• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
• Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.

A natural avalanche cycle occurred over the past few days as it rained to near mountain top, followed by clear skies and warm temperatures. Storm slab and wet loose avalanches (size 1-2) occurred on all aspects and elevations.

A crust will form on the surface overnight, making avalanche activity unlikely. If dry snow exists in alpine terrain, human-triggered wind slabs are possible.

A crust or moist snow exists on the surface at most elevations due to recent rain and warm temperatures. Below this, the upper snowpack has various depths of moist or wet snow from recent rain.

There are multiple crusts in the mid- and lower snowpack, and it is generally dense and well-settled.

The average snowpack depth at treeline is roughly 150 to 200 cm.
