As of 4am on Sunday, tropical storm Talim over the upper South China Sea packing sustained winds of about 85 kilometres per hour was slowly moving in the north-northwest direction. It was expected to move over Hainan island and make landfall in upper Vietnam on July 18-19.
Meanwhile, over July 16-20 a strong monsoon trough will move over the North, Northeast and Central regions of Thailand while another strong southwestern monsoon prevails across the Andaman Sea, the South and the Gulf of Thailand.
