Eight Thai provinces face flash flood risk as monsoon intensifies
Residents of high-risk provinces including Chiang Rai, Phayao, Nan, Phrae, Loei, Bueng Kan, Chanthaburi and Trat have been advised to exercise extreme caution due to the threat of heavy to very heavy rainfall and accumulated precipitation. The conditions may trigger flash floods and forest runoff, especially in hillside areas near waterways and low-lying zones.
Sea conditions remain moderate, with upper Andaman Sea waves reaching approximately two metres. The lower Andaman Sea and upper Gulf of Thailand are experiencing waves of one to two metres, with areas of thunderstorms producing waves exceeding two metres. Mariners operating in the Andaman Sea and Gulf of Thailand are advised to navigate with caution and avoid areas with thunderstorms.
The northern region faces thunderstorms across 70% of the area, with heavy to very heavy rainfall expected in Mae Hong Son, Chiang Mai, Chiang Rai, Phayao, Nan, Phrae, Tak, Sukhothai, Uttaradit, Phitsanulok and Phetchabun provinces. Temperatures will range from 23-26 degrees Celsius at night to 29-34 degrees during the day, with southwesterly winds at 10-20 kilometres per hour.
The northeastern region faces thunderstorms covering 70% of the area, with heavy rainfall in Loei, Nong Khai, Bueng Kan, Udon Thani, Nong Bua Lamphu, Sakon Nakhon, Nakhon Phanom, Mukdahan, Amnat Charoen and Ubon Ratchathani provinces. Temperatures will range from 22-26 degrees Celsius overnight to 29-33 degrees during the day.
The central region faces thunderstorms across 60% of the area, with heavy rainfall in Nakhon Sawan, Uthai Thani, Kanchanaburi and Ratchaburi provinces. Temperature ranges will be 24-26 degrees Celsius at night and 32-34 degrees during the day.
The eastern region faces thunderstorms covering 70% of the area, with heavy to very heavy rainfall expected in Nakhon Nayok, Prachin Buri, Sa Kaeo, Chachoengsao, Chon Buri, Rayong, Chanthaburi and Trat provinces. Temperatures will range from 24-28 degrees Celsius overnight to 30-34 degrees during the day, with southwesterly winds at 15-35 kilometres per hour and sea waves of one to two metres.
The southern region's eastern coast faces thunderstorms across 40% of the area, with heavy rainfall in Chumphon, Surat Thani and Nakhon Si Thammarat provinces. The western coast faces thunderstorms covering 60% of the area, with heavy rainfall expected in Ranong, Phang Nga, Phuket and Krabi provinces.
Bangkok and surrounding areas face thunderstorms across 60% of the region, with temperatures ranging from 26-27 degrees Celsius at night to 32-35 degrees during the day, accompanied by southwesterly winds at 10-20 kilometres per hour.
The severe weather pattern results from a monsoon trough extending across upper Myanmar, upper northern Thailand, upper northeastern Thailand and upper Vietnam. A low-pressure system covering southern China is moving along the monsoon trough, whilst the moderate southwest monsoon covering the Andaman Sea, Thailand and the Gulf of Thailand is expected to strengthen.

Heavy rain alert as tropical storm Wipha approaches Thailand
Thailand is bracing for heavy rain this week after tropical storm Wipha triggered the opening of an around-the-clock monitoring centre. The Thai Meteorological Department's (TMD) 24-hour war room was launched to keep track of the storm, which on Monday was centred over the Gulf of Tonkin with wind speeds reduced from 116 km/h to 83 km/h. Widespread downpours are nonetheless expected. TMD director-general Sukanyanee Yawincharn stated that Wipha was moving west-southwest at 20 km/h and was expected to make landfall in northern Vietnam yesterday before further weakening. Despite not making direct landfall in Thailand, Wipha is intensifying the southwest monsoon, leading to forecasts of heavy to very heavy rain across 50 provinces, while in Bangkok, thunderstorms are expected across 60%–80% of the city. Ms Sukanyanee said that although Wipha will not directly hit Thailand, it is likely to cause flash floods, forest run-off, and rough seas. The TMD will maintain 24-hour surveillance and issue continuous updates. Seree Supratid, director of the Climate Change and Disaster Center at Rangsit University, posted on Facebook that Thailand's Department of Disaster Prevention and Mitigation had convened an emergency meeting, led by director-general Phasakorn Boonyalak, to assess Wipha's potential impacts. The meeting resolved that the National Disaster Warning Centre would inform 22 high-risk provinces via cell broadcast of the expected landfall today. The storm will likely weaken to a depression before crossing into northern Thailand, especially affecting Nan and Chiang Rai. Acting Prime Minister Phumtham Wechayachai warned that flash floods are the main concern, and flood response equipment has been deployed in key areas.

Tourist boat capsizes in Vietnam's Ha Long Bay, leaving 34 dead
HANOI - A tourist boat ferrying families around Vietnam's Ha Long Bay capsized in a storm on Saturday afternoon, leaving at least 34 people dead, according to state media reports, as rescuers scrambled to locate the missing. The vessel was carrying 48 passengers and five crew members when it capsized in the UNESCO World Heritage site because of sudden heavy rain, the VNExpress news site said. Most of those on board were families visiting from the capital Hanoi, with more than 20 children among the passengers, it said. "Border guards rescued 11 people and recovered 34 bodies," it added. Rescue efforts were set to continue into the night to find the eight still missing. Ha Long Bay office worker Tran Trong Hung told AFP the storm started in the afternoon. "The sky turned dark at around 2 pm (0700 GMT)," he said. There were "hailstones as big as toes with torrential rain, thunderstorm and lightning", he said. One of the rescued, a 10-year-old boy, told state media outlet VietnamNet: "I took a deep breath, swam through a gap, dived, then swam up. I even shouted for help, then I was pulled up by a boat with soldiers." Prime Minister Pham Minh Chinh sent his condolences to the families of the deceased and called on the defense and public security ministries to conduct urgent search and rescue. Authorities would "investigate and clarify the cause of the incident and strictly handle violations", a statement on the government website said. Torrential rain also lashed northern Hanoi, Thai Nguyen and Bac Ninh provinces on Saturday. In the capital about 175 kilometres (110 miles) away, several trees were knocked down by strong winds. The storm followed three days of intense heat, with the mercury hitting 37 degrees Celsius in some areas. Mai Van Khiem, director of the National Center for Hydrometeorological Forecasting, was quoted in VNExpress as saying that the thunderstorms in northern Vietnam were not caused by the influence of Tropical Storm Wipha in the South China Sea. Ha Long Bay is one of Vietnam's most popular tourist destinations, with millions of people visiting its blue-green waters and rainforest-topped limestone islands each year. Last year, 30 vessels sank at boat lock areas in coastal Quang Ninh province along Ha Long Bay after Typhoon Yagi brought strong wind and waves.
