High Tide Flood Warning Issued for Bangkok and Seven Provinces in Thailand

The Office of the National Water Resources (ONWR) and the Department of Disaster Prevention and Mitigation (DDPM) have issued a high tide flood warning for Bangkok and seven central and southern provinces from November 9 to 14, 2026. Strong easterly winds are pushing seawater into the Gulf of Thailand, causing water levels in four major rivers (Bang Pakong, Chao Phraya, Tha Chin, Mae Klong) to rise 0.10–0.30 meters above critical levels. Low-lying riverside communities, areas outside flood barriers, and major roads like Sukhumvit Road and Rama II Road are at high risk of flooding. Authorities have urged residents to prepare for potential waterlogging, flash floods, rapid runoff, and mudslides, and to move valuables to higher ground.
