Talas-17 is a category 1 tropical cyclone that affected the north-central coast of Vietnam and Lao PDR. This cyclone originated on 14 July 2017 in the South China Sea (northwest Pacific) at a speed of about 37 km/h. On 16 June 2017, tropical cyclone Talas-17 made landfall on the Hà T?nh Province, Vietnam and moved a few hours later towards the Bolikhamxai Province, Lao PDR with a maximum sustainable wind speed of 93 km/h. The tropical cyclone is soon expected to dissipate on land, however heavy rains are forecasted over the next few days, which may outcome flash floods and landslides.Based on data of the observed and predicted tropical cyclone path, wind speeds from JRC (Warning 6 issued on 16 July 2017 at 21:00 UTC), and population data from WorldPop, UNITAR-UNOSAT conducted a population exposure analysis for Vietnam and Lao PDR.
