Travel and Terrain Advice

Watch for changing conditions today, storm slabs may become increasingly reactive.

Caution around convexities or sharp changes in terrain.

Approach lee and cross-loaded slopes with caution.

Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
