Urgent Weather Alert Issued
Preparing for Natural Disasters
On June 30, 2025, Thailand’s Department of Disaster Prevention and Mitigation (DDPM) issued a critical warning for 17 provinces, urging residents to prepare for flash floods, landslides, and forest runoff from July 1 to July 5. The alert follows severe flooding in areas like Phaya Mengrai, Chiang Rai, where volunteers are already aiding recovery efforts. This proactive measure aims to mitigate risks as heavy rainfall looms over multiple regions.
Affected Regions Identified
Northern, Northeastern, and Southern Risks
The DDPM highlighted four northern provinces—Chiang Rai, Phayao, Nan, and Tak—alongside nine northeastern provinces, including Loei, Bueng Kan, and Ubon Ratchathani, as high-risk areas. Central provinces Chanthaburi and Trat, and southern provinces Ranong and Phangnga, also face threats. Rising water levels in the Ing and Mekong Rivers could exacerbate conditions, impacting agriculture and infrastructure in these areas, which saw $1.2 billion in damages from floods in 2024.
Monsoon and Weather Patterns
Heavy Rainfall Forecast
The Thai Meteorological Department (TMD) predicts heavy to very heavy rain from July 1 to July 6, driven by a monsoon trough affecting northern and northeastern Thailand, intensified by southwestern winds from the Andaman Sea and Gulf of Thailand. Bangkok and its surrounding areas expect thunderstorms affecting 60-70% of the region, increasing urban flooding risks. These conditions mirror 2024’s severe floods, which impacted 181,870 households, per DDPM reports.
Reservoir and River Monitoring
Safeguarding Water Systems
The DDPM emphasized close monitoring of small to medium-sized reservoirs, which are vulnerable to overflow during heavy rains. The Ing River in Chiang Rai and the Mekong River, affecting provinces like Nong Khai and Mukdahan, are rising, posing risks to riverside communities. Enhanced monitoring, supported by the Office of National Water Resources, aims to prevent repeats of 2024’s $46.5 billion economic losses from flooding, particularly in agriculture.
Community Preparedness Urged
Proactive Evacuation and Safety Measures
Residents are advised to stay vigilant, monitor weather updates, and prepare evacuation plans, especially in mountainous and low-lying areas prone to landslides and flash floods. The DDPM’s emergency hotline and collaboration with mobile networks like AIS and True ensure rapid alerts, as seen in Nan’s recent evacuation orders. These measures build on lessons from 2024, when 45 fatalities were reported due to floods and landslides across Thailand.
Ongoing Response Efforts
Learning from Recent Disasters
Thailand’s disaster response system, led by the DDPM, is mobilizing resources, with local authorities and volunteers ready to assist. The 2024 floods, which affected 37 provinces and caused $4 billion in damages in Chiang Rai alone, underscore the need for swift action. By leveraging real-time weather data and community engagement, Thailand aims to minimize disruptions and protect its 66 million residents from the impending weather threats.
