Public demo · no sign-up. Real live data, but not for safety or operational decisions. Facilities are saved only in this browser (localStorage) — no account, no server database. Rounded coordinates (~110 m) are sent directly from your browser to Open-Meteo, GDACS (global list only, no coordinates) and, for US locations, the National Weather Service.
