Travel and Terrain Advice

Be carefull around freshly wind loaded features.

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

Potential for wide propagation exists, fresh slabs may rest on surface hoar, facets and/or crust.

Avoid exposure to overhead hazards when solar radiation is strong.
