Thailand braces for heavy rainfall and flash floods this week
Thailand faces an alert for heavy to very heavy rainfall from today to July 18, which may cause flash floods and forest runoff, especially in Bangkok. The Thai Meteorological Department (TMD) has issued a warning for the entire country.
The Thai Meteorological Department, led by Gorravee Sitthichivapak, announced that from today to July 18, a strong monsoon trough will pass through the northern and northeastern regions of Thailand, merging with a low-pressure system over the central South China Sea.
This, combined with a strong southwest monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand, will result in increased rainfall. Heavy to very heavy rain is expected in several areas across the country.
Residents are advised to be cautious of the dangers posed by heavy rainfall, which could lead to flash floods and forest runoff, particularly in foothill areas near waterways and low-lying regions. Extra caution is also recommended when travelling through areas experiencing thunderstorms.
The northern provinces expected to experience heavy to very heavy rainfall today include Chiang Rai, Phayao, Nan, and Tak. In the northeast, the provinces of Nong Khai, Bueng Kan, Nong Bua Lamphu, Udon Thani, Sakon Nakhon, Nakhon Phanom, Mukdahan, Yasothon, Kalasin, Khon Kaen, Maha Sarakham, Roi Et, Amnat Charoen, Si Sa Ket, and Ubon Ratchathani are on high alert.
Central Thailand will see heavy rains in Kanchanaburi and Ratchaburi, while the eastern provinces of Nakhon Nayok, Prachin Buri, Sa Kaeo, Rayong, Chanthaburi, and Trat are also expected to be heavily affected. In the south, Phetchaburi, Prachuap Khiri Khan, Chumphon, Surat Thani, Ranong, Phang Nga, Phuket, and Krabi will face significant rainfall.
