Warning: HVZ Baden-Württemberg forecast
Warning. The forecast may contain inaccuracies. The forecast data for this gauge is (partly) sourced from the Hochwasservorhersagezentrale Baden-Württemberg. The small chart you see when clicking the hyperlink for this gauge is the only format in which this public authority publishes its forecast. Unfortunately, the digitisation has only resulted in a very low‑resolution image. The algorithm that converts that image back into numeric values for this table may sometimes be wrong because it must OCR axis labels that are also low resolution, and cannot be guaranteed 100% correct. Always verify the original chart if the numbers appear implausible.
