North Rockies

Assess for wind slabs in steep terrain near ridgetop and on crossloaded features at treeline.

Moderate

• We are uncertain due to a limited number of field observations.

We haven't received any recent reports of avalanches.

It remains possible that riders could trigger small wind slabs near ridgetop.

Please share any observations to the Mountain Information Network.

15 to 35 cm of snow overlies a hard melt-freeze crust. The amount of snow depends on aspect and elevation.

Strong southwesterly wind has stripped windward areas down to the crust in many areas, and built small wind slabs on leeward slopes and crossloaded features. These wind slabs may remain triggerable on Friday.

• Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
• Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
