Wind slabs, formed by northerly winds, can be found on lee features in the alpine and may not bond well to a recently formed crust. Use caution as you transition into wind-affected areas.
No new avalanches were reported.
Isolated wind slabs may be possible to human-trigger. The most likely terrain is directly lee of high spots and ridge features.
Even short windows of sun may be enough to develop moist surface snow that may produce wet loose avalanche activity.
Roughly 20 cm of new snow has accumulated over a melt-freeze crust on all aspects and elevations. A second crust formed in late March can also be found in the upper snowpack at variable depths depending on aspect and elevation.
A persistent weak layer of facets sits on top of a second buried crust down 80 to 180 cm. This layer is unlikely to be human-triggered in areas where a thick crust above the weak layer is present.
