NASA looked into Hurricane Maria and found that powerful convective storms within the hurricane were dropping heavy rainfall. Maria brought that heavy rainfall to Puerto Rico and made landfall on Sept. 20 at 6:15 a.m. EDT.

The Global Precipitation Measurement mission, or GPM, core observatory satellite collected data on rainfall rates as it passed above Hurricane Maria earlier on Sept. 19 at 9:51 p.m. AST/EDT (Sept. 20 0151 UTC). The rainfall analysis was derived from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data received by the satellite. GPM's radar (DPR Ku band) found that some extreme storms within the hurricane's feeder bands were dropping rain at a rate of greater than 5.4 inches (137 mm) per hour.
