NASA's Integrated Multi-satellitE Retrievals (IMERG) data were used in this analysis to show total rainfall accumulation estimates during the period from October 27 - 31, 2017. Tropical storm Philippe formed and dissipated during that period. The tropical storm formed over the western Caribbean from tropical depression eighteen on October 28, 2017. Philippe then drenched western Cuba as it moved toward the northeast. It dropped a reported 10 inches (254 mm) of rain over southeastern Florida before dissipating in the Atlantic Ocean. Moisture from Philippe's remnants added to heavy rainfall

The GPM satellite showed the distribution and intensity of precipitation on the eastern side of the low pressure center. The approximate location of the storm's center at the time of the GPM pass is shown with a large red "L". GPM's Microwave Imager (GMI) showed that a large area of intense rain was located in the Atlantic east of the low's center. GMI estimated that rain in that area was falling at rates of greater than 2 inches (51 mm) per hour. GPM's Precipitation Radar (DPR) instrument showed that the low was dropping rain at a rate of over 4.92 inches (125 mm) per hour in a small area
