The category 4 Tropical Storm ETA-20 reached the coast of southern Puerto Cabezas in the afternoon of 3 November. With maximum sustained winds up to 240 km/h. According to GDACS, Tropical Cyclone ETA-20 can have a high humanitarian impact based on the maximum sustained wind speed, exposed population, and vulnerability.Based on data of the forecasted tropical cyclone path of wind speeds zones from Joint Research Centre (Issued on 4 November 2020 00:00 UTC), and population data from WorldPop 2020, UNITAR-UNOSAT has prepared a population exposure analysis for the Nicaragua. About 3% of population of the Nicaragua living inside wind speed zone exceed 120 km/h, 5% living inside wind speed zone of 60-120 km/h and 30% living inside wind speed zone below 60 km/h https://unitar.org/unosat/node/44/3164 https://www.gdacs.org/contentdata/maps/unosat/TC/1000738/NICARAGUA_ETA_Population_Exposure_Analysis_Report_20201104.jpg guid_2 Wed, 04 Nov 2020 11:32:21 Tropical cyclone ETA-20 formed on 31 October 2020 over the Caribbean Sea east of Nicaragua with the maximum sustained winds up to 240 km/h. The category 4 Tropical Storm ETA-20 reached the coast of southern Puerto Cabezas in the afternoon of 3 November. With maximum sustained winds up to 240 km/h. According to GDACS, Tropical Cyclone ETA-20 can have a high humanitarian impact based on the maximum sustained wind speed, exposed population, and vulnerability. Based on data of the forecasted tropical cyclone path of wind speeds zones from Joint Research Centre (Issued on 5 November 2020 03:00 UTC), and population data from WorldPop 2020, UNITAR-UNOSAT has prepared a population exposure analysis for the Honduras. About 1% of population of the Honduras living inside wind speed zone of 60-120 km/h and 11% living inside wind speed zone below 60 km/h. https://unitar.org/unosat/node/44/3169 https://www.gdacs.org/contentdata/maps/unosat/TC/1000738/HONDURAS_ETA_Population_Exposure_Analysis_Report_20201105.jpg guid_3 Thu, 05 Nov 2020 14:06:34 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. https://unitar.org/unosat/node/44/3175 https://www.gdacs.org/contentdata/maps/unosat/TC/1000738/UNOSAT_A3_Natural_Portrait_TC20201103NIC_AtlanticoNorte_Nicaragua_08112020.jpg guid_4 Wed, 11 Nov 2020 11:15:56
