Using thermal images of Harvey taken on Aug. 25, 2017 (left) and Irma taken on Sept. 5, 2017 (right), by NASA-NOAA's Suomi NPP satellite to show the systems' storm swirl at their strongest and online mapping tool MAPfrappe, we imagined what Category 4 Harvey and Category 5 Irma would look like in other areas of the United States.
