From 16 to 20 July, the strong monsoon trough will move down to the North, the Northeast and the upper Central. Meanwhile, the strong southwest monsoon prevails across the Andaman Sea, the South of Thailand and the Gulf. More rains are likely across the country while isolated heavy to very heavy rains are possible in the North, the Northeast, the Central including Bangkok and its vicinity, the East and the South regions. People should beware of severe conditions that may cause flash floods and overflows especially along waterways and lowlands and take more caution in thundershowers.
The strong wind forces the waves in the Andaman Sea and the upper Gulf of Thailand 2-4 meters high and thundershowers more than 4 meters. In the lower Gulf, waves are 2-3 meters high and thundershowers more than 3 meters high. All ships should proceed with caution and keep off thundershowers. In the Andaman Sea and the upper Gulf of Thailand, ships keep ashore.
In addition, the tropical depression over the upper South China is forecast to develop into a tropical storm and move pass through Hainan before making landfall over upper Vietnam on 18 and 19 July.
This final advisory is in effect on 14 July 2023, at 5.00 p.m.
