Get the aggregated NHC tropical overlay as GeoJSON.
Returns a single GeoJSON FeatureCollection aggregating the latest National Hurricane Center tropical overlay: forecast cone, track line, forecast points, and coastal watch/warning segments for every active storm, plus the 7-day Tropical Weather Outlook (TWO) areas. Each feature carries a kind property the client uses to pick its renderer (cone, track, points, watch_warning, two); the properties bag is forward-compat. Latest TCD and TCP bulletins for active storms live on the FeatureCollection foreign member discussions[] (joined by ATCF id, e.g. text AT1 → AL01). Latest TWO text is on the same array, keyed by basin storm_id (AT / EP / CP). They are not copied onto every cone/track/point feature.
The endpoint takes no parameters.
