Tropical Depression No. 1 (187/2023)

At 7.00 p.m. on 14 July, the tropical depression in the upper South China Sea was centered at latitude 17.0 degrees north, longitude 119.0 degrees east, with sustained winds of about 55 km/hr. Moving southwest at a speed of about 20 km/hr, the storm likely to intensify into a tropical storm passing through Hainan. It is forecast to make landfall over upper Vietnam by 18 and 19 July.

From 16 to 20 July, the active monsoon trough will move down across the North, the Northeast and the upper Central regions. Meanwhile, the strong southwest monsoon prevails over the Andaman Sea and the Gulf of Thailand. This causes more rain with isolated heavy to very heavy rains across the country. People should beware of the severe conditions that may cause flash floods and overflows, especially along foothills  near waterways and lowlands. All transport takes more caution. 

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.   

This advisory is in effect on 14 July 2023, at 11.00 p.m.

This next issue will be on 15 July 2023, at 5.00 a.m.
