An event's reported location, extent and status may update at different times depending on the source. Verify critical decisions with official emergency agencies.
Event records come from NASA EONET, supplemented by USGS FDSN landslide records. Storm analyses and forecasts may use NOAA NHC or JTWC, with historical ATCF records from UCAR/NCAR. Satellite imagery is supplied through NASA Worldview/GIBS (GOES and Himawari) or EUMETSAT Meteosat, depending on map coverage.
