- Its four river-flow forecasts are scaled to long-run means and described as guides, not measurements.
Field notes
Rain forecasts are fetched when opened and kept for 15 minutes. For river-flow predictions, the page explains that GloFAS models flows on a roughly 5 km grid, then scales them against each river’s long-run mean. It also documents practical map choices: estuary rivers stop at the county boundary, and heritage railways are omitted. Data-source links name the providers and applicable licences.
