Horizon is a free app that tells you if you are in a floodplain and warns you when river flooding or heavy rainfall is predicted at your location. We combine daily forecasts from the Global Flood Awareness System (GloFAS), a global river model informed by satellite data, with flood-hazard maps. Since the model is global, it is especially useful in areas of the world without official flood forecasts or local weather predictions (always follow your local authorities).

Could you build this?
Partial The UI wrapper is simple, but ingesting, processing, and spatially querying massive global GIS hydrological datasets from GloFAS alongside high-resolution elevation models requires specialized geospatial infrastructure.
What it would actually take: Requires automated geospatial pipelines to ingest NetCDF/GRIB data streams from Copernicus GloFAS, intersecting polygon flood hazard layers using PostGIS or GeoPandas against user coordinates. Setting up high-precision real-time hydrological alert notifications requires GIS engineering expertise and pipeline orchestration (e.g., Apache Airflow).
