How this was made

Everything comes from the archive of official AEMET warnings that Climaviso has kept since June 2018: each day counts once, at the highest level the zone had. A warning is a forecast, not damage or a measurement, and it's issued for the whole zone, not your street. We don't cover measured temperatures or rainfall: only when, and why, a warning was issued.
