The level of the Phetchaburi River is under close scrutiny at the Special Centre for Crisis Management as water released from Kaeng Krachan Dam could cause overflows in the province’s Muang district later on Tuesday.
Border provinces along the Mekong River were also in peril amid heavy downpours in Laos, with Nakhon Phanom and Ubon Ratchathani on high alert for flooding.
Eight other provinces face varying levels of risk as heavy rains continue, the centre reported – Bueng Kan, Sakhon Nakhon, Chanthaburi, Trat, Ranong, Krabi, Trang and Satun.
Reservoirs at five are at levels exceeding the “upper rule curve”, meaning they’re above 80 per cent capacity.
Kaeng Krachan Dam is at 109 per cent of capacity, Nam Oon Dam in Sakhon Nakhon at 101 per cent, Vajiralongkorn Dam in Kanchanaburi at 90 per cent, Khun Dan Pra Kan Chon Dam in Nakhon Nayok at 86 per cent and Pran Buri Dam in Prachuap Khiri Khan at 86 per cent.
