Separately, the Department of Disaster Prevention and Mitigation (DDPM) has placed 16 central and southern provinces on flood alert from November 9 to 13 as the TMD forecast heavy to very heavy rain, Nation Thailand reported on November 9. The DDPM alert covers Phetchaburi and Prachuap Khiri Khan in the central region, together with all 14 southern provinces: Chumphon, Surat Thani, Nakhon Si Thammarat, Phatthalung, Songkhla, Pattani, Yala, Narathiwat, Ranong, Phang Nga, Phuket, Krabi, Trang and Satun. The two notices have different scopes and neither replaces the other.

The Bangkok tide risk, morning by morning

A Chao Phraya high tide could flood low-lying riverside and canal areas of Bangkok and six central provinces from November 9 to November 17, the DDPM warned. DDPM Director-General Nirat Pongsitthithavorn said the department issued the alert after reviewing water conditions alongside Announcement No. 15/2569, which the Royal Thai Navy's Hydrographic Department published on November 5.

Near Royal Thai Navy Headquarters in Bangkok, water is expected to reach 1.70 to 2.00 metres above mean sea level between about 7:30am and 1:30pm from November 9 to 16, close to the 2-metre critical mark, so water could seep through gaps in flood walls, piers and drains. At Phra Chulachomklao Fort near the river mouth in Samut Prakan, levels of 1.80 to 1.90 metres are forecast between about 6am and noon from November 9 to 17, above the 1.70-metre critical mark there, which could send water over the banks.

The DDPM told Bangkok and six central provinces to prepare: Pathum Thani, Nonthaburi, Nakhon Pathom, Samut Sakhon, Samut Songkhram and Samut Prakan. In Bangkok it singled out areas along the Chao Phraya and its canals, especially low-lying communities outside the flood walls and places with no permanent flood defences. The Office of the National Water Resources issued its own watch for November 9 to 14 covering eight provinces, adding Chachoengsao on the Bang Pakong River, as well as the Tha Chin and Mae Klong rivers.

A TMD bulletin issued at 5am on November 9 and reported by Nation Thailand forecast heavy to very heavy rain across southern Thailand from November 9 to 13, with Phuket listed for heavy rain on November 12, and warned that accumulated rainfall could trigger flash floods and rapid run-off, particularly on foothill slopes near waterways and in low-lying areas. The conditions were attributed to a relatively strong high-pressure system from China spreading over upper Thailand and the South China Sea and strengthening easterly winds, with a temperature drop of 3-5 degrees Celsius forecast in the Northeast and 1-3 degrees in the North, Central region, Bangkok and the East.

What happens next: the risk window runs through November 13 for the southern heavy rain and through November 17 for the Bangkok-area tides, with the greatest river risk each morning. The DDPM takes calls for help on its 24-hour 1784 hotline and on LINE at @1784DDPM, and the Navy publishes daily Chao Phraya water levels — residents in the named districts should follow those daily updates rather than treat this week's forecast as a guarantee either way.
