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.
15 to 20 cm of new snow and extreme southwest winds formed wind slabs on lee aspects at upper elevations. These slabs are most likely to be reactive on steep slopes below ridgetops.
On Tuesday, numerous skier triggered size 1 wet loose avalanches were reported on sunny aspects below treeline.
Last week's rain and warm temperatures triggered a widespread natural slab avalanche cycle up to size 3.
If you are heading into the backcountry, please consider sharing conditions via the MIN.
15 to 20 cm of new snow and extreme southwest winds formed wind slabs on lee aspects at upper elevations. These slabs are most likely to be reactive on steep slopes below ridgetops. The new snow sits on a thick crust.
The snowpack below is moist to ground, and well consolidated in most locations. The snowpack depth tapers rapidly at lower elevations.
