About the weather maps for Cobb Mountain Area

Each preview is centered on Cobb Mountain Area, with the red pin marking its approximate location. Satellite imagery provides cloud context, radar shows nearby precipitation, and the fog view shows the marine-layer or low-cloud field when that regional layer is available.
