Small wind slabs may exist in Leeward terrain features.

Use caution as you transition into wind-affected terrain.

Moderate

• We are uncertain due to variable freezing levels.

Numerous wet loose avalanches up to size 2.5 were reported at the Seaton riding area on Friday.

Observations are still limited, so be sure to post yours to the MIN if you get out!

A few centimetres of new snow on Saturday night will overlie a crust formed by this week's warm temperatures and rain, extending to at least 1800 m.

In the alpine, wind slabs overlie a hard crust that extends up to 2300 m. Surface hoar can be found on this crust in some locations at treeline.

A second layer of facets or surface hoar is buried around 50 to 100 cm deep, and is considered unlikely to trigger at this point.

The mid and lower snowpack have no layers of concern. Snowpack depths are around 150-200 cm at treeline.

• Wind slabs are isolated, but may remain reactive.
• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
