Image of Subtropical Storm Issa over KwaZulu-Natal Province of South Africa on April 11, 2022. The heavy rains from the storm caused major flash and river flooding in KwaZulu-Natal Province. The underlying true-color image was acquired on April 11, 2022 by the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument, the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite. Colors overlaid on the base image indicate precipitation rates based on Integrated Multi-satellitE Retrievals for the Global Precipitation Measurement (GPM) (IMERG) data. Red in this image show rates of about 5mm to 10mm/hour; and green in this image show rates of about 0.1mm to 1mm/hour. Data for this image are collected by multiple satellites in the the joint NASA/Japan Aerospace Exploration Agency Global Precipitation Measurement (GPM) Core Observatory.
