Although wind slabs are expected to be small, minimize exposure to terrain traps where a small avalanche could have more serious consequences.
Keep using good travel habits this season
New and more reactive wind slabs may be found, as new snowfall is expected Sunday night and throughout Monday. Avoid areas near ridgeline that feel "drum like" or hollow.
On Sunday a size 1 naturally triggered wind slab was reported. Reports have been limited since Wednesdays storm - indicating that conditions have improved, but reactivity still exists in certain wind affected features.
Alpine terrain is heavily wind-affected, while sheltered areas have around 30-50 cm of settling snow from recent storms.
A mix of rain and sun crusts exist beneath the recent snow with facets surrounding the crusts. Neighbouring regions have reported surface hoar at these interfaces, but no observations suggest it is an issue in this region.
Treeline snow depths in the Okanagan region average 110 cm.
