BANGKOK — 3 July 2026, The Department of Disaster Prevention and Mitigation (DDPM) is closely monitoring Tropical Storm Maysak, which is expected to bring heavier rainfall to many parts of Thailand despite not making landfall in the country.
The DDPM, through the National Disaster Warning Centre, said the storm is forecast to pass over Hainan Island before making landfall in southern China between 4 and 6 July.
Although Maysak is not expected to move directly into Thailand, the agency warned that it will strengthen the southwest monsoon, resulting in increased rainfall nationwide, with isolated heavy to very heavy rain.
As of Friday, the storm’s centre was located over the northern South China Sea, packing maximum sustained winds of around 74 kilometres per hour and moving north-northwest.
According to forecast tracks, Maysak will cross Hainan Island before moving ashore in southern China between 4 and 6 July. While Thailand lies outside the storm’s direct path, its circulation is expected to enhance the southwest monsoon, increasing rainfall across much of the country.
Authorities urged residents, particularly those living in areas prone to flash floods, forest runoff and landslides, to closely monitor official weather forecasts and disaster warnings and follow instructions issued by local officials.
The DDPM also encouraged the public to stay updated through official weather bulletins. Emergency assistance is available around the clock via the department’s 1784 hotline.
