Source: Department of Meteorology. We check its site every two hours and store a report only when it changes. The department publishes only its latest files, so history here begins with the first report we stored; days before that are modelled at the stations from Open-Meteo’s historical archive and marked as such. Districts are those the forecast and advisories name, or the districts of the provinces they name.
