Hamburg Heavy Rain Map & Severity Index
Hamburg's municipal water utility publishes a public rain map that recalculates precipitation across the metropolitan region every five minutes from German Weather Service radar plus its own gauges, grading events on a twelve-step heavy-rain index across 24,000 grid cells. It informs residents and authorities; no reading automatically triggers pumps or sewer control.
🎓 Lesson
A reading here has no operational consequence: this sits on the public-warning rung of the sensor-to-action ladder, one step below a forecast — Hamburg Wasser's own retention-basin network is still checked by staff on site, not by the index.
