Krovanh originated from a tropical disturbance within the monsoon trough east of Chuuk State on August 13 . Despite rather favorable conditions , the initial tropical depression did not intensify significantly and degenerated into a remnant low on August 18 . However , these remnants were able to reorganize and the system was reclassified as a tropical cyclone a day later . Intensification was rather rapid upon the storm 's reformation – the depression reached tropical storm status on August 20 and then typhoon intensity two days later . Shortly after , Krovanh made landfall on Luzon at peak intensity with winds of 120 km / h ( 75 mph ) . The typhoon emerged into the South China Sea as a much weaker tropical storm , though it was able to restrengthen over warm waters . Once again at typhoon intensity , Krovanh clipped Hainan before moving over the Leizhou Peninsula on its way to a final landfall near Cẩm Phả , Vietnam on August 25 . Quick weakening due to land interaction occurred as Krovanh moved across northern Vietnam , where the storm met its demise the following day .
