Tropical Storm "Vamco" formed on November 9, 2020, as the 22nd named storm of the 2020 Pacific typhoon season. By 12:00 UTC on November 10, Vamco intensified into a Severe Tropical Storm. The Office of Civil Defense (OCD) of Philippines had raised a red alert status in Bicol Region (Region 5). According to PAGASA, the center of Vamco is more likely to make landfall over Quezon early Thursday morning, November 12, with a close approach of Catanduanes and Camarines Norte tomorrow afternoon and evening (LT), respectively. According to GDACS, Tropical Cyclone VAMCO-20 can have a medium 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 11 November 2020 08:00 local time), and population data from the WorldPop 2020, UNITAR-UNOSAT has prepared a population exposure analysis for the Philippines. About 10% of population of the Philippines living inside wind speed zone exceed 120 km/h, 26% living inside wind speed zone of 60-120 km/h and 31% living inside wind speed zone below 60 km/h. https://unitar.org/unosat/node/44/3176 https://www.gdacs.org/contentdata/maps/unosat/TC/1000741/PHILIPPINES_VAMCO_Population_Exposure_Analysis_Report_Philippines_20201111.jpg guid_1 Wed, 11 Nov 2020 11:30:41 This map illustrates satellite-detected surface waters in Albay and Camarines Sur provinces of Philippines as observed from a Sentinel-1 image acquired on 12 November 2020 at 05:38 local time. Within the analyzed area of about 5,000 km2, a total of about 250 km2 of lands appear to be flooded. The water extent appears to have increased of about 130 km2 since 6 November 2020. Based on Worldpop population data and the detected surface waters, about 170,000 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. https://unitar.org/unosat/node/44/3177 https://www.gdacs.org/contentdata/maps/unosat/TC/1000741/UNOSAT_A3_Natural_Protrait_TC20201111PHL_Albay_CmarinesSur_12112020.jpg guid_2 Thu, 12 Nov 2020 14:08:39 This map illustrates satellite-detected surface waters in Camarines Norte province of Philippines as observed from a Sentinel-1 image acquired on 12 November 2020 at 05:38 local time.
