Lynnea Baker,
A winter interlude in the middle of spring has us thinking about winter problems again. Watch for windslabs in alpine and treeline lees.
Be prepared to travel in spring conditions again later this week.

Confidence
Due to the number of field observations
Problems
Wind Slabs
New snow and strong SW winds are forming wind slabs in immediately and ridge crests. Slabs sit top refrozen surfaces and may well not bond
- Use caution in lee areas. Recent wind loading has created wind slabs.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
