Weather Maps

About the weather maps for Belmont

Each preview is centered on Belmont, 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.

These images cover a wider area than the point forecast, so a nearby cloud or rain band may not be directly over Belmont. Open a preview for the interactive map and its latest timestamp before making a weather-sensitive decision.
