This map illustrates satellite detected potentially damaged buildings within the affected neighborhoods in Djibouti, Djibouti District, Djibouti Region, Djibouti. Potentially affected neighborhoods were defined according to field data. The analysis was conducted by analyzing a post-event Pleiades image acquired on 23 May 2018, after the passage of Tropical Cyclone Sagar-18, compared with a pre-event WorldView-2 image acquired on 23 April 2018.
UNITAR-UNOSAT, following the request of UNOCHA Djibouti , has performed a flood analysis to illustrate the potential impact in the wake of Tropical Cyclone Sagar-18 over the city of Djibouti.
UNOSAT analysis illustrates the potential satellite detected water extent within the city of Djibouti and classifies the areas as:

This map illustrates the total August rainfall accumulation for East Africa, derived from the CMORPH precipitation dataset at a spatial resolution of approximately 10km for this region, and was calculated using microwave and infrared data from geostationary satellites. It is possible that precipitation levels may have been underestimated for local areas, and is not a substitute for ground station measurements.
