🌦 weather: waiting for a replay…
Overflow timing usually matches river rises because both are driven by the same rainfall — a timing match is not evidence that either caused the other.
The map shows the weather that caused the flood under the rivers it flooded, on one clock. Each circle is a river gauge: it grows and turns red as that river climbs toward the highest level ever measured there. ▲ beside it is how fast it is rising, in cm per hour. Each rain gauge glows with the rain of the last hour, on the same colour scale as the model's rain band under the map. The band and the isobars are ERA5, a reanalysis: a model run with the observations of the time, not measurements.
The small map in the corner is the whole weather system, so you can see where the low is while the main map stays on your area. Click it to zoom out, click again to come back.
The timeline under the map is your doorstep: rain every 15 minutes at the nearest rain gauge, the nearest river as a share of its record, warnings as flags. The future is ghosted until the clock reaches it, so at every moment you see only what a person there could have known. Click or drag on it to move the clock.
The panel on the right is right now, at your door: the last hour's rain, the river's level and rise, the warnings out, the pressure. Below it, the story: the moments that mattered, ticked off as the clock passes them. Click one to jump to it.
Speed is replay time per real second. At 1 hour per second a day takes 24 seconds. ← → step 15 minutes (with shift, an hour); space plays and pauses.
