DDPM puts 16 Thai provinces on flood alert for 9–13 November
Thai disaster authorities have ordered round-the-clock readiness and shelter preparations as heavy rain threatens central and southern provinces.
- Thailand's Department of Disaster Prevention and Mitigation (DDPM) has issued a flood alert for 16 provinces in the central and southern regions from November 9 to 13.
- The alert is in response to a forecast of heavy to very heavy rain, which brings the risk of flash floods, rapid runoff, and mudslides.
- The affected areas include two central provinces (Phetchaburi and Prachuap Khiri Khan) and all 14 southern provinces.
- Authorities in the 16 provinces have been instructed to prepare personnel and equipment for 24-hour assistance and to ready potential evacuation shelters.
Thailand’s Department of Disaster Prevention and Mitigation (DDPM) issued an alert on 9 November 2026 for 16 central and southern provinces facing heavy to very heavy rain over 9–13 November. Flash floods, rapid runoff, mudslides and waterlogging are possible, with authorities instructed to prepare personnel and equipment for round-the-clock assistance.
Nirat Pongsitthithavorn, DDPM director-general and head of the central disaster prevention and mitigation command, said the alert followed an assessment of weather conditions and risk factors, alongside a Thai Meteorological Department advisory issued at 5pm on 8 November.
The Thai Meteorological Department forecasts continued rain across the South over 9–13 November, with heavy rainfall in many areas and isolated very heavy falls. A relatively strong high-pressure system, or cold air mass, from China is expected to extend across upper Thailand and the South China Sea, strengthening easterly winds over Thailand and the Gulf of Thailand.
Flood watch covers all 14 southern provinces and two central provinces
The DDPM’s flood watch for 9–13 November covers the following provinces, grouped by region:
- Central region, two provinces: Phetchaburi and Prachuap Khiri Khan.
- South, 14 provinces: Chumphon, Surat Thani, Nakhon Si Thammarat, Phatthalung, Songkhla, Pattani, Yala, Narathiwat, Ranong, Phang Nga, Phuket, Krabi, Trang and Satun.
The DDPM has instructed authorities to alert residents in vulnerable areas in advance so they can prepare for possible flooding. Provincial agencies must closely monitor weather conditions, rainfall and local water levels.
DDPM calls for 24-hour readiness and preparations for evacuees
The central disaster prevention and mitigation command has coordinated with the 16 provinces and four regional disaster centres to ensure teams, machinery and response vehicles are ready to provide immediate assistance, around the clock, if conditions worsen or flooding spreads.
The regional centres involved are Region 4 in Prachuap Khiri Khan, Region 11 in Surat Thani, Region 12 in Songkhla and Region 18 in Phuket.
The DDPM has called for drainage efforts to be accelerated, particularly in locations with a history of repeated flooding and areas that remain inundated, to minimise further damage.
Authorities responsible for natural tourist attractions, particularly caves, waterfalls and caves with waterways, have been instructed to issue warnings and prevent access if conditions pose a danger.
Provincial authorities must also coordinate preparations for temporary shelters, food, drinking water and other essential supplies to accommodate evacuees if flooding occurs.
