Forecast valid time

Standing archive of NHC/CPHC advisory forecast track, cone-of-uncertainty and watches/warnings bundles, with related wind-field files, published as downloadable shapefile/KML packages by storm and advisory. This Source preserves forecast-at-issuance evidence and is distinct from final HURDAT2 post-analysis. Geometry remains in source files and is not flattened into speculative scalar Features.

Commercial standing flood forecasting and monitoring platform for buyer-specified property points and wider polygons. It continuously reruns hydrodynamic models, displays forecast time and depth in a dashboard, issues alerts, and exposes continuously updated point, polygon, and mapping feeds through an API for integration into customer risk-management systems. Optional connected sensors add observed local water-level telemetry; modelled forecasts and sensor readings must not be conflated.
