GPM'S IMERG data on Hurricane Dorian

Caption

As of early on August 30, 2019 Hurricane Dorian has been producing 2 to 6 inches of rain along the path of its inner core for several days. This estimate come from the NASA IMERG algorithm, which combines observations from a fleet of satellites, in near-realtime, to provide global estimates of precipitation every 30 minutes. The storm-total rainfall at a particular location varies with the forward speed of the hurricane, with the size of the hurricane's wind field, and with how vigorous the updrafts are in the hurricane's eyewall. The graphic also shows the distance that tropical-storm force (39 mph) winds extend from the Hurricane Dorians low-pressure center, as reported by the National Hurricane Center. The symbols H2, H1, and TS represent category 2 hurricane, category 1 hurricane, and tropical storm, respectively.
