Old wind slabs can be found in standard lee features. New wind slabs are expected to form from light to moderate northeasterly winds. Watch out for reverse loading.
Triggering wind slabs remains the primary concern. Use caution in wind loaded features as rider triggered wind slabs are likely.
Pay close attention to reverse loading over the weekend.

Several wind slab avalanches were observed in the last 48 hours. These avalanches were from alpine and treeline start zones and up to size 2.5.
Up to 65cm of new snow is being redistributed into wind slabs in lee features. This sits over variable surfaces including widespread wind affected snow and a new 3-8cm thick crust treeline and below treeline. Beneath this, 30–50 cm of settled snow overlies multiple crusts. The lower snowpack is generally well settled.
