Millions of people in Mozambique, Malawi and Zimbabwe are struggling to cope with the aftermath of what could be the southern hemisphere’s worst storm: Cyclone Idai. This image is from Copernicus Sentinel-1 and shows part of the flooding, depicted in red, to the east of the Zambezi River in Mozambique and Malawi. The image comprises two satellite acquisitions, one from 2 March before the cyclone hit and one from 20 March in the wake of the cyclone. The mission is also supplying imagery through the Copernicus Emergency Mapping Service to aid relief efforts.
