DDPM Warns 61 Provinces and Bangkok to Prepare for Heavy Rain and Strong Winds Southern Region to Watch for Flooding Nov 5-9, 2026

The Department of Disaster Prevention and Mitigation (DDPM) has warned 61 provinces and Bangkok to prepare for thunderstorms and strong winds, while the southern region should be on alert for heavy to very heavy rainfall from November 5 to 9, 2026.

On November 3, 2026, Mr. Nirat Pongsitthaworn, Director-General of the Department of Disaster Prevention and Mitigation (DDPM), stated that the DDPM, as the Central Disaster Prevention and Mitigation Command Center (CDPMCC), has been monitoring weather conditions and assessing risk factors. The Meteorological Department issued its second bulletin (No. 285/2569) on November 2, 2026, at 05:00 am, regarding unstable weather in upper Thailand and heavy to very heavy rain in the southern region. From November 5 to 7, 2026, upper Thailand will experience unstable weather characterized by thunderstorms, strong gusts, and heavy rain in some areas, initially affecting the northeastern region. Subsequently, the northern, central regions, including Bangkok and its vicinity, and the eastern region will be impacted.

From November 7 to 9, 2026, the southern region will experience increased rainfall, with heavy rain in many areas and very heavy rain in some places. This is due to a high-pressure system or another cold air mass from the People's Republic of China extending over upper Thailand and the South China Sea, resulting in stronger easterly winds covering Thailand and the Gulf of Thailand. The specific areas under close watch are as follows.

Areas under surveillance for thunderstorms and strong gusts during November 5 to 7, 2026.

• Northern region: 16 provinces including Chiang Mai, Chiang Rai, Lamphun, Lampang, Phayao, Phrae, Nan, Uttaradit, Tak, Sukhothai, Kamphaeng Phet, Phitsanulok, Phichit, Phetchabun, Nakhon Sawan, and Uthai Thani.
  
  

• Northeastern region: 10 provinces including Loei, Nong Khai, Bueng Kan, Nong Bua Lam Phu, Udon Thani, Sakon Nakhon, Chaiyaphum, Khon Kaen, Nakhon Ratchasima, and Buriram.
  
  
• Central region: 21 provinces including Kanchanaburi, Ratchaburi, Suphanburi, Chai Nat, Sing Buri, Ang Thong, Phra Nakhon Si Ayutthaya, Lopburi, Saraburi, Nakhon Nayok, Prachinburi, Chonburi, Rayong, Phetchaburi, Prachuap Khiri Khan, Pathum Thani, Nonthaburi, Nakhon Pathom, Samut Sakhon, Samut Songkhram, and Samut Prakan.

Areas to monitor for flash floods, runoff floods, landslides, and waterlogging during November 5 to 9, 2026.

• Southern region: 14 provinces including Chumphon, Surat Thani, Nakhon Si Thammarat, Phatthalung, Songkhla, Pattani, Yala, Narathiwat, Ranong, Phang Nga, Phuket, Krabi, Trang, and Satun.

Accordingly, the Central Disaster Prevention and Mitigation Command Center (CDPMCC) has coordinated with 61 provinces and Bangkok, as well as regional disaster prevention and mitigation centers in risk areas, to prepare for the unstable weather and heavy to very heavy rainfall in some places, which may cause flooding.

They are closely monitoring weather, rainfall, and water situations. If conditions worsen or spread, response teams with disaster machinery and operation vehicles will be deployed immediately to assist people 24/7, especially in areas prone to frequent floods or ongoing flood situations. Efforts will focus on rapidly draining water to minimize flood impact. For natural tourist sites, especially caves and waterfalls, if hazards arise, warnings should be issued, and areas closed to prevent access. At the same time, related agencies should prepare temporary shelters, food, drinking water, and essentials to support evacuees during floods.

The public is urged to follow weather forecasts and official updates closely, particularly those in risk areas who must strictly heed warnings. They should inspect homes and structures to ensure stability, avoid open spaces, under large trees, billboards, or unstable constructions to prevent injury from falling objects, and be cautious of lightning. Farmers should protect their crops from potential damage.

If affected or in need of assistance, people can report incidents and request help via the DDPM emergency Line "1784 Incident Reporting" Line ID @1784DDPM or the emergency hotline 1784, available 24 hours a day.
