DDPM puts 61 provinces and Bangkok on alert for November 5–9, with storms in upper Thailand and heavy rain raising flood risks in the South.
- Thailand's disaster agency has placed Bangkok and 61 provinces on alert for severe weather from November 5-9 due to a high-pressure system from China.
- Upper Thailand is expected to face thundershowers and gusty winds, while the 14 southern provinces are on watch for heavy rain, flash floods, and landslides.
- In response, authorities have put emergency personnel and equipment on 24-hour standby, prepared shelters, and urged residents to secure their homes.
Thailand’s Department of Disaster Prevention and Mitigation (DDPM) has placed 61 provinces and Bangkok on alert for severe weather from November 5–9, 2026, with thundershowers and gusty winds expected in upper Thailand and heavy rain raising flood and landslide risks in the South.
Authorities have been instructed to keep emergency personnel and disaster-response equipment ready around the clock, accelerate drainage in vulnerable communities and prepare temporary shelters for possible evacuations.
DDPM Director-General Nirat Pongsitthaworn, who also heads the Central Disaster Prevention and Mitigation Command, said the preparations followed an assessment of weather conditions and risk factors, alongside the Thai Meteorological Department’s Advisory No. 2.
A fresh 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.
Upper Thailand faces thundershowers and gusty winds
Thundershowers and gusty winds are forecast in upper Thailand on November 5–7. The Northeast is expected to be affected first, followed by the North, Central region, including Bangkok and surrounding provinces, and the East.
The storm watch covers 47 provinces, as well as Bangkok. The provinces are grouped in the DDPM alert as follows.
Northern region — 16 provinces: 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: Loei, Nong Khai, Bueng Kan, Nong Bua Lamphu, Udon Thani, Sakon Nakhon, Chaiyaphum, Khon Kaen, Nakhon Ratchasima and Buri Ram.
Central and Eastern regions — 21 provinces: Kanchanaburi, Ratchaburi, Suphan Buri, Chai Nat, Sing Buri, Ang Thong, Phra Nakhon Si Ayutthaya, Lop Buri, Saraburi, Nakhon Nayok, Prachin Buri, Chon Buri, Rayong, Phetchaburi, Prachuap Khiri Khan, Pathum Thani, Nonthaburi, Nakhon Pathom, Samut Sakhon, Samut Songkhram and Samut Prakan.
All 14 southern provinces on flood watch
The DDPM’s flood watch covers all 14 southern provinces from November 5–9, with rainfall expected to intensify on November 7–9.
Heavy to very heavy rain could trigger flash floods, rapid runoff, mudslides and localised flooding.
The provinces are Chumphon, Surat Thani, Nakhon Si Thammarat, Phatthalung, Songkhla, Pattani, Yala, Narathiwat, Ranong, Phang Nga, Phuket, Krabi, Trang and Satun.
Rescue teams and equipment on 24-hour standby
The DDPM has instructed local authorities to prepare long-distance water-pumping vehicles, flood-response vehicles, flat-bottomed boats and rapid-response teams for immediate deployment.
Areas that experience repeated flooding, together with communities where floodwater has yet to recede, have been told to install pumps and clear water-flow routes to speed up drainage.
Authorities must also assess risks at natural tourist attractions, particularly caves, cave passages and waterfalls. Where there is a risk of flash flooding or sudden runoff, the affected areas must be closed and entry prohibited.
Local agencies have been directed to prepare temporary shelters, food, relief packages and clean drinking water so they can accommodate residents promptly if evacuations become necessary.
Residents urged to secure homes and protect crops
Residents in at-risk areas should inspect their homes, roofs and other structures to ensure they can withstand strong winds. Branches near buildings should also be trimmed to reduce the danger from falling debris.
During thundershowers, people should avoid open spaces, large trees, unstable billboards and temporary structures, while remaining alert to lightning.
Farmers are advised to reinforce livestock shelters, cover agricultural produce and maintain drainage in their fields to limit damage from gusty winds and waterlogging.
The DDPM urged residents to follow weather forecasts and official announcements closely, and to comply with warnings issued by local authorities.
People affected by storms, flooding or other disasters can request free, round-the-clock assistance through the DDPM hotline on 1784 or its official LINE account, @1784DDPM.
