Title
Satellite detected water extents between 13 and 17 August 2025 over South Sudan
Description
**UNOSAT code: FL20250110SSD** This map illustrates cumulative satellite-detected water using VIIRS in South Sudan between 13 to 17 August 2025, compared with the period from 25 to 29 April 2025. Within the cloud-free analysed areas of about 620,000 km², a total of about 26,000 km² of land appears to be affected by flood waters. Water extent appears to have increased of about 15,000 km² since the period between 25 to 29 April 2025 within the cloud-free analysed areas. Based on Worldpop population data and the maximal flood water extent ~416,000 people are potentially exposed or living close to flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT).
