Heavy Rain Shifts West; 10 Provinces At Risk
A monsoon system is shifting westward, bringing heavy rainfall to 10 provinces including Kanchanaburi and Ratchaburi on September 26, with conditions expected to improve by September 28. The Chao Phraya River is rising but poses no major fl
On September 26, Assoc. Prof. Seree Supratid, director of the Climate Change and Disaster Research Center at Rangsit University, posted on Facebook that rain systems are increasingly moving toward the western region. Heavy to very heavy rainfall is expected today, with forecasts showing intense activity concentrated in the western and some central provinces: Kanchanaburi, Ratchaburi, Phetchaburi, Uthai Thani, Suphan Buri, Nakhon Pathom, Chai Nat, Nakhon Sawan, Tak, and Kamphaeng Phet.
Bangkok and its vicinity, along with other central and eastern regions, will experience moderate to heavy rain, with significant decline expected from September 27 onward, except for the western region. Conditions should normalize by September 28, with only some northern western areas seeing continued rain.
For the Chao Phraya Basin, the Royal Irrigation Department reported increased water discharge through Chao Phraya Dam at approximately 1,850 cubic meters per second. Low-lying areas outside embankments are experiencing rising water levels. However, Seree stressed that a major flood event comparable to 2011 is not expected. The critical indicator of major flooding would be northern water sources overflowing embankment capacity—currently flowing at 1,800 cms compared to 4,600 cms in 2011.
