Satellite detected water extent Valdesia Region, Dominican Republic as of 21 November 2023

**UNOSAT code: FL20231120DOM, GDACS ID: 1102342** This map illustrates cumulative satellite-detected water extent in Higuamo & Valdesia Regions, Dominican Republic as observed from a Sentinel-2 image acquired on the 21 November 2023 at 11:17 local time. Within the cloud free analysed area of about 1,800 km² , about 35 km² of land appears to be affected with flood waters and 14,000 people are potentially exposed to flood waters. 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: FL20231120DOM, GDACS ID: 1102342** This map illustrates cumulative satellite-detected water extent in CIbao Nordeste and Cibao Sur Regions, Dominican Republic as observed from a Sentinel-1 image acquired on the 18 November 2023 at 18:53 local time. Within the extent of this map, about 55 km² of land appears to be affected with flood waters and about 10,500 people are potentially exposed to flood waters 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). 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.
