Heavy rain is likely to prevail in all regions from Aug 2-4, according to the Thai Meteorological Department’s 11am weather forecast on Sunday.
The department said at 10am on Sunday, tropical storm “Sinlaku” made landfall over Vietnam. It was centred at Thanh Hoa, Vietnam, with maximum sustained winds of about 65 kilometres per hour. The storm was moving in the west-northwest direction at 15km/hr and was expected to be downgraded to a tropical depression over Laos before becoming a low pressure cell.
The storm, in conjunction with a strong monsoon trough lying across the North and the upper Northeast and the southwest monsoon over the Andaman Sea and the Gulf of Thailand, is likely to cause heavy to very heavy rain in many areas of the North, Northeast, Central, East and South regions.
