It's still winter up high; expect to find wind slabs on lee features in the alpine.
Sunny periods are expected on Saturday. At this time of year when the sun is more intense, it doesn't take much to heat up southerly slopes. Keep an eye out for changing conditions throughout the day.

Avalanche Summary
No new avalanche observations.
Snowpack Summary
10-20cm of recent snow has been redistributed by South to SW winds in the Alpine. It is still very much winter conditions above 2800m. Solar slopes and all aspects at tree line and below have a plethora of crusts in the upper snow pack. The Feb 3 PWL is down 40-100cm and remains a concern on shaded aspects above 2400m. The basal depth hoar/facets are gaining strength in deeper snowpack areas.

Problems
Wind Slabs
Ongoing moderate to strong winds have formed wind slabs on previous hard surfaces (sun crusts and old wind slabs). These have not bonded yet to the old surfaces.
Aspects: All aspects.
Elevations: Alpine.

Expected Size
Persistent Slabs
This problem seems to be most active where the March 19th crust is not supportive over the Feb 3rd weak layer (down 30-90cm) of facets over a crust. This problem remains a concern on shaded aspects above 2400m.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine.
