Fresh wind slabs will build throughout the day with new snow and wind. Be mindful as you travel into lee terrain and near ridge crests, where slabs will be more reactive.
New snow and wind will create fresh wind slabs. Slab size and sensitivity to triggering will likely increase through the day as new snow accumulates.
On Monday, dry loose avalanches were easily triggered by skiers on steep northerly slopes while unstable wet snow was observed on southerly slopes due to solar radiation throughout the region.
Thanks for sharing your observations via the MIN if you are going out into the backcountry.
20 to 25 cm of recent snow exists, with deeper deposits of wind-transported snow in lee terrain at upper elevations. Southerly slopes have been sun-affected and the surface snow is moist and/or heavy snow.
This sits over 120 cm of settling storm snow from the past week. The snow reportedly has a good bond to the underlying crust. Southerly slopes were affected by the sun, resulting in heavy wet snow, especially at lower elevations.
Below this, the snowpack is well-settled and strong.
