The Department of Disaster Prevention and Mitigation (DDPM) has issued warnings for 29 provinces in the North, Northeast, and South to watch for flash floods, sudden flooding, and waterlogging from 8 to 10 May 2026. They are accelerating coordination with officials to be ready to assist people in vulnerable areas promptly.
On 8 May 2026 at 11:00 a.m., Mr. Theeraphat Kachamat, Director-General of the DDPM, revealed that the Central Disaster Prevention and Mitigation Command (CDPMC) has been monitoring weather conditions and risk factors. Following the resolution from the National Warning War Room meeting on 7 May 2026, they issued alerts to monitor disaster-prone areas.
This is because a high-pressure system or cold air mass from China will extend over the Northeast and the South China Sea. Combined with southerly and southeasterly winds bringing moisture from the Gulf of Thailand and the South China Sea over northern Thailand, and the strengthening easterly winds over the South and the Gulf of Thailand, heavy rain is expected. This may cause flash floods, sudden flooding, and waterlogging in the North, Northeast, and South from 8 to 10 May 2026. The areas to monitor are as follows.
The Central Disaster Prevention and Mitigation Command, through the DDPM, has coordinated with provinces and regional disaster prevention centers in risk areas to prepare for heavy rainfall that may cause flooding. They have instructed officials to closely monitor weather, rainfall amounts, and water conditions in these areas.
Special attention is given to areas with heavy or prolonged rainfall. Preparations include readying disaster machinery, Emergency Response Teams (ERT), and assigning personnel to monitor risk areas around the clock. For natural tourist spots, especially caves and waterfalls, if risks arise, authorities will issue warnings and strictly prohibit entry. Provinces are urged to communicate via all media channels so people can stay informed about weather and official updates, and receive advance warnings to prepare and act safely during disasters.
The public can follow disaster alerts via the THAI DISASTER ALERT app, available on both iOS and Android, as well as through the official DDPM social media accounts on Facebook (Department of Disaster Prevention and Mitigation DDPM) and X (@DDPMNews).
If affected by a disaster, people can report incidents and request assistance through the LINE account “DDPM Incident Report 1784” by adding the LINE ID @1784DDPM, or via the 24-hour emergency hotline 1784 for coordination and support.
