Emergency Alerts Map

* Weather layers (rain, temperature, wind) show live conditions; during playback they switch to the hourly snapshot archive (last 30 days) and hide beyond it. Day/night and planet overlays follow the playback time. Overlapping alerts from different sources are grouped - click a group to see every report. Event data is aggregated from public emergency feeds and may be delayed or incomplete - always rely on official local sources for safety decisions.
