THAILAND – Authorities warned that southern Thailand faced a heightened risk of flash floods, fast-moving water and landslides after forecasts predicted heavy rain between 21 and 25 October.
Official warning and scope
The Disaster Prevention and Mitigation Department issued alerts for 14 southern provinces, urging residents and local governments to prepare for “strong to very strong” rainfall that the National Water Authority said could push rivers over their banks and destabilise slopes. The warning identified low-lying areas and cities with poor drainage as particularly vulnerable, noting that prolonged downpours have repeatedly triggered floods in past seasons.
Areas at risk
Officials named a string of coastal and inland provinces as being among those at highest risk, including Chumphon, Surat Thani, Nakhon Si Thammarat, Songkhla, Yala, Narathiwat, Ranong, Phang Nga, Phuket, Krabi, Trang and Satun. Regions along the Tapee, Trang, Saiburi and Pattani rivers were singled out, with authorities saying river levels there could rise sharply within hours.
Reservoirs and flood triggers
Several reservoirs in the region were being monitored closely. Some were already more than 80 percent full, the alert said, and further rainfall could cause them to spill, increasing flood risk downstream. Officials warned that even a few hours of persistent rain could turn small streams into fast, destructive torrents.
Emergency response measures
Local emergency centres in Surat Thani, Songkhla and Phuket were placed on heightened alert and mobile teams equipped with heavy machinery were put on standby to clear roads and assist evacuations. “We called on the public to remain vigilant and to follow weather warnings closely,” a spokesman for the Disaster Prevention and Mitigation Department said, urging people living on slopes or near rivers to secure their homes and be ready to evacuate.
How residents can get help
Authorities advised residents to download the THAI DISASTER ALERT app for real-time updates. A 24-hour emergency hotline, 1784, and the Line ID @1784DDPM were made available for those needing assistance.
Watchful days ahead
Officials stressed that early preparation could save lives and reduce damage. Over the coming days they said they would continue to monitor river gauges and reservoir levels closely as they worked to keep transport routes open and communities informed. The next 72 to 120 hours will determine whether the rains pass with limited impact or turn the south into another scene of floodwater and mud.
