In a sea of wind affected surfaces, wind slabs remain a concern and may be tricky to recognize.
Avoid large open slopes capable of producing large avalanches.
Because of their dense, stubborn nature, and the possibility of a weak layer underneath, they may fracture wider than anticipated and with no warning.
Several size 1-1.5 rider triggered slabs have been reported in the last 3 days. Recent activity has mainly occurred at treeline elevations and on north or west facing slopes. Wind slabs are still catching riders off guard, including accidental and remotely triggered releases.
Outflow winds have sculpted the snowpack. Most exposed terrain is sastrugi or has been scoured down to old crusts. On sheltered slopes, wind slabs persist.
20 to 60 cm of snow overlies a crust and/or surface hoar layer in isolated, wind-sheltered terrain features (primarily at treeline and below).
A January crust with associated facets is buried 100 to 200 cm deep. Below, the remaining snowpack is generally well settled and well bonded.
