High tide surges and heavy rainfall warned from May 23-31

The National Water Resources Office (NWRO) has issued a warning to monitor for high tide surges from May 23-31, 2024. Coupled with heavy rainfall in several areas, river levels are expected to rise further, potentially impacting major rivers. The Meteorological Department reports widespread rain in all regions, with heavy to very heavy rain in some areas. They also warn of possible flash floods, forest runoff, and strong winds.


The NWRO advises monitoring for high tide surges during May 23-31, 2024. With heavy rain expected in many areas during this period, river levels are expected to rise, possibly affecting low-lying areas along the Chao Phraya, Mae Klong, Tha Chin, and Bang Pakong rivers. These areas, especially those outside flood defenses and temporary barriers in provinces such as Samut Songkhram, Samut Sakhon, Nakhon Pathom, Nonthaburi, Bangkok, and Samut Prakan, are at risk of flooding.
