The Hainan Provincial Meteorological Observatory issued a warning on the 24th, forecasting the formation of a tropical depression in the South China Sea.
From now till September 26th, Hainan Island and the western-central South China Sea are expected to experience heavy rainfall and strong winds as a result of the weather system’s approach.
Current meteorological data indicates the development of a tropical cloud cluster in the western-central South China Sea. It is expected to intensify into a tropical depression and move in a westward direction, gaining some strength along the way. The depression is forecasted to make landfall along the central coastal areas of Vietnam during the night of Monday, September 25th.
Hainan Island is expected to witness heavy rainfall and strong winds.
Around September 29th, a new tropical cyclone is expected to form in the eastern-central South China Sea. This cyclone is predicted to move north-westward, intensify, and gradually approach the western parts of Guangdong and the eastern coastal regions of Hainan, potentially affecting the region with more adverse weather conditions.
