Satellite detected waters in Peten Department of Guatemala & Chiapas State of Mexico as of 22 November 2020

**UNOSAT code: TC20201119GTM** This map illustrates satellite-detected surface waters in Alta Verapaz, Izabal and Zacapa departments of Guatemala as observed from a Sentinel-1 image acquired on 18 November 2020 at 18:06 local time. Within the analyzed area of about 15,000 km2, a total of about 170 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 17,500 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: TC20201119GTM** This map illustrates satellite-detected surface waters in Izabal department of Guatemala as observed from a Sentinel-1 image acquired on 23 November 2020 at 05:45 Local time. Within the analyzed area of about 6,000 km2, a total of about 150 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 8,600 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.

This map illustrates satellite-detected surface water extent in the northern part of Guatemala covering Chisec, Coban Ixcan and Sayaxche municipalities, using a Sentinel-1 satellite image acquired on the 09 October 2017. Sentinel-1 imagery acquired on 3 and 5 October 2017 was used as pre crisis imagery. UNITAR-UNOSAT analysis shows an expansion of water of ~ 4,600 has over the analyzed municipalities, being Sayaxche the municipality that was affected the most with an expansion of flood waters of ~ 3,200 Ha. The exact limit of flood waters is uncertain because of the low spatial resolution of the satellite data used for this analysis. Please send ground feedback to UNITAR - UNOSAT.

**UNOSAT code: TC20201103NIC** This map illustrates satellite-detected surface waters in Puerto Cabezas, Prinzapolka and Launa de Perlas Municipality, Nicaragua as observed from Sentinel-1 image acquired on 08 November 2020. Within the analyzed area of about 12,000 km2, a total of about 1,200 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 7,500 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 areasand densely vegetated areas due to backscattering properties of the radar signal.

**UNOSAT code: TC20201013VNM** This map illustrates satellite-detected surface waters in Thua Thien Hue Province of Viet Nam as observed from a Sentinel-1 image acquired on 22 October 2020. Within the analyzed area of about 4,000 km2, a total of about 220 km2 of lands appear to be flooded. The water extent appears to have receded of about 90 km2 since 13 October 2020. Based on Worldpop population data and the detected surface waters, about 70,000 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: TC20201101PHL** This map illustrates satellite-detected surface waters in Albay and Camarines Sur provinces Philippines as observed from a Sentinel-1 image acquired on 1 November 2020 at about 17:57 local time. Within the analyzed area of about 5,000 km2, a total of about 240 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 160,000 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.
