On June 2, a low-pressure area was developed into a tropical depression over the West Philippine Sea with a westward direction until it curved northward. After three days, the depression upgraded to a tropical storm and naming it Ewiniar. Shortly thereafter, Ewiniar made landfall over South China. Ewiniar maintained its intensity while over land and continues to traverse the South China Sea in eastward direction.On June 9, Ewiniar had weakened into a tropical depression and degenerated into a low pressure area. However, the low-pressure area continues to traverse the sea before dissipating on June 13.
