Kernpunkte

The most likely places to trigger a lingering wind slab will be in steep, high-consequence terrain. Don't let your guard down and assess often.

    Wind slabs may continue to linger directly, lee of features like high points and ridges, and may be poorly bonded to a melt-freeze crust.

Avalanche Summary

A few size 1 wind slabs and wet loose avalanche activity were reported on Saturday. Read about them in this MIN

Several small explosive-triggered wind slabs and size 1 to 1.5 wet loose from steep solars on Friday.

Snowpack Summary

Recent accumulated snow is settling on north-facing slopes and is moist on steep south-facing slopes, which overlies a crust on all aspects and elevations that is more robust on solar-facing slopes.

A widespread crust with facets above is down 60 to 110 cm. This layer is unlikely to human trigger in areas where a thick crust above the weak layer is present.
