Heavy rainfall to hit 37 provinces: Stay alert for flash floods

Heavy rainfall is expected in 37 provinces across Thailand this week, with a 60% chance of precipitation, according to the Thai Meteorological Department (TMD). The country and parts of Bangkok are on alert for potential flash floods, prompting residents to exercise caution as accumulated rainfall increases the risk.

These weather conditions are a result of low-pressure troughs affecting the northern region of the country and the upper part of Laos, combined with a moderate southwestern monsoon covering the Andaman Sea. The TMD released a 24-hour forecast, with advice for people from various regions, mainly concerning the dangers of heavy rainfall and flash floods.

In the Northern region, there is a 60% chance of thunderstorms, accompanied by heavy rain in areas such as Tak, Mae Hong Son, Chiang Mai, Chiang Rai, and Phetchabun provinces. The lowest temperatures range from 23-26 degrees Celsius and the highest from 32-36°C. A southwestern wind with speeds of 10-20 kilometres per hour is also predicted.

The northeastern region also faces a 60% risk of thunderstorms, and possibly heavy rainfall in Nong Khai, Udon Thani, Nakhon Phanom, Maha Sarakham, and Ubon Ratchathani provinces. Minimum temperatures are expected to be between 25-26°C and maximum temperatures between 32-36°C. The wind speed is forecasted at 10-20 km/h.

Central Thailand will experience similar weather conditions, with a 60% chance of thunderstorms in provinces such as Lopburi, Saraburi, Kanchanaburi, Ratchaburi, Samut Songkhram, and Samut Sakhon. Minimum temperatures vary from 24-28°C, and maximum temperatures from 36-38°C. A southwest wind with speeds of 10-20 km/h is predicted.

The eastern region sees a 70% chance of thunderstorms, with heavy downpours in places such as Nakhon Nayok, Prachin Buri, Chanthaburi, and Trat provinces. The lowest temperatures are between 25-29°C, and the highest are 31-35°C. Winds are expected to blow from the southwest at speeds of 20-35 km/h.

For the southern region, a 60% chance of storms is expected, especially in Phetchaburi, Prachuap Khiri Khan, Chumphon, Surat Thani, Pattani, and Narathiwat provinces. Minimum temperatures are expected to range from 24-27°C, and the maximum temperatures range from 30-34°C.

Bangkok and surrounding provinces are also likely to experience a 60% chance of thunderstorms and heavy rainfall. The lowest temperatures range from 27-29°C, and the highest is between 34-38°C, with a southwest wind at a speed of 10-25 km/h.
