The Thai Meteorological Department (TMD) has issued a warning for today, July 14, indicating that 39 provinces in Thailand will experience heavy rainfall, covering 60% of the area.
Seven provinces, including Mae Hong Son, Chiang Mai, Chiang Rai, Phayao, Nan, Nong Khai, and Bueng Kan, are advised to prepare for potential hazards such as flash floods and runoff.
The weather forecast for the next 24 hours predicts thunderstorms and heavy rain in parts of the country due to a monsoon trough passing over northern Thailand and Laos, extending into a low-pressure area in northern Vietnam. Additionally, a strong southwest monsoon is affecting the Andaman Sea, Thailand, and the Gulf of Thailand.
In the north, heavy rain is expected in Mae Hong Son, Chiang Mai, Chiang Rai, Lamphun, Lampang, Phayao, Nan, Tak, Phitsanulok, and Phetchabun. Temperatures will range from 24 to 27 degrees Celsius at the lowest to 33 to 36 degrees Celsius at the highest. Winds will blow from the southwest at speeds of 10 to 20 kilometres per hour.
The northeast will see heavy rain in Loei, Nong Khai, Bueng Kan, Nong Bua Lamphu, Udon Thani, Sakon Nakhon, Nakhon Phanom, Khon Kaen, Kalasin, Mukdahan, Amnat Charoen, and Ubon Ratchathani. Temperatures will vary between 24 and 26 degrees Celsius for the low and 30 and 35 degrees Celsius for the high, with southwest winds at 10 to 20 kilometres per hour.
Central Thailand, including Lopburi, Saraburi, and Kanchanaburi, will also experience thunderstorms and heavy rain in 40% of the area. Temperatures will range from 24 to 26 degrees Celsius to 34 to 36 degrees Celsius, with southwest winds at 10 to 20 kilometres per hour.
