Satellite detected water extents between 13 & 17 November 2020 in Honduras

**UNOSAT code: TC20201116HND** This map illustrates satellite-detected surface waters in Colon and Yoro Departments of Honduras as observed from a Sentinel-1 image acquired on 18 November 2020 at 18:06 Local time. Within the analyzed area of about 5,200 km2, a total of about 220 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 82,000 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 UNITAR-UNOSAT. Important Note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to backscattering properties of the radar signal.

**UNOSAT code: TC20201116HND** This map illustrates satellite-detected surface waters in Atlantida and Yoro Departments of Honduras as observed from a Sentinel-1 image acquired on 18 November 2020 at 05:37 Local time. Within the analyzed area of about 3,000 km2, a total of about 40 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 1,200 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 UNITAR-UNOSAT. Important Note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to backscattering properties of the radar signal.

**UNOSAT code: TC20201116HND** This map illustrates satellite-detected surface waters in Olancho Department of Honduras as observed from a Sentinel-1 image acquired on 18 November 2020 at 05:37 Local time. Within the analyzed area of about 4,400 km2, a total of about 32 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 900 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 UNITAR-UNOSAT. Important Note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to backscattering properties of the radar signal.

**UNOSAT code: TC20201116NIC** Este mapa ilustra las inundaciones detectadas por el satélite NOAA-VIIRS en Nicaragua entre el 13 y 17 de Noviembre. Dentro del área analizada de aproximadamente 95,000 km2, un total de aproximadamente 2,000 km2 de tierras parecen estar inundadas. Basado en los datos de población de Worldpop y la extensión de las aguas superficiales detectadas, alrededor de 100,000 personas están potencialmente expuestas o viven cerca de áreas inundadas. La población potencialmente expuesta se encuentra principalmente en el departamento de Chinandega con ~25,000 habitantes, en el departamento de Manague con ~16,000 habitantes, y em el departamento de Atlántico Norte con 10,000 habitantes. Se trata de un análisis preliminar que aún no ha sido validado en el terreno. Por favor envíe comentarios a UNITAR-UNOSAT.

**UNOSAT code TC20221014NIC** This map illustrates cumulative satellite-detected water using VIIRS in Nicaragua between 12 to 16 October 2022 compared with the period from 27 September to 01 October 2022. Within the cloud free analyzed areas of about 240,000 km², a total of about 3,200 km² of lands appear to be affected. Water extent appears to have increased of about 2,300 km² since the period between 27 September to 01 October 2022. Based on Worldpop population data and the maximal flood water extent ~120,000 people are potentially exposed or living close to flooded areas amongst the 6,570,000 people living in cloud free 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).

**UNOSAT code TC20221014NIC** This map illustrates cumulative satellite-detected water using VIIRS in Region Autonoma del Atlantico Norte, Nicaragua between 12 to 16 October 2022 compared with the period from 27 September to 01 October 2022. Within the cloud free analyzed areas of about 30,000 km², a total of about 1,900 km² of lands appear to be affected. Water extent appears to have increased of about 1,400 km² since the period between 27 September to 01 October 2022. Based on Worldpop population data and the maximal flood water extent ~8,500 people are potentially exposed or living close to flooded areas amongst the 29,000 people living in cloud free 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).
