Abstract. In this communication, we present application of the
automated near-real-time (NRT) system called RAdar-Produced Inundation Diary
(RAPID) to European Space Agency Sentinel-1 synthetic aperture radar (SAR) images to produce flooding
maps for Hurricane Dorian in the northern Bahamas. RAPID maps, released 2 d after the event, show that coastal flooding in the Bahamas reached
areas located more than 10 km inland, covering more than 3000 km2 of
continental area. RAPID flood estimates from subsequent SAR images show the
recession of the flood across the islands and present high agreement scores
when compared to Copernicus Emergency Management Service (Copernicus EMS)
estimates.
