Tropical Storm Maysak to Boost Thailand Rainfall
Tropical Storm Maysak will strengthen southwest monsoon winds and boost rainfall across Thailand between July 4-6, though the storm itself is expected to hit Hainan Island and southern China instead.
BANGKOK — July 3, 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 direct landfall in the country.
Through the National Disaster Warning Centre, the DDPM said the storm is forecast to pass over Hainan Island before making landfall in southern China between July 4-6.
Although Maysak will not 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 in some areas.
As of Friday, the storm's centre was located over the northern South China Sea, with maximum sustained winds around 74 kilometres per hour, moving north-northwest.
According to forecast tracks, Maysak will cross Hainan Island before moving ashore in southern China between July 4-6. 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 in areas prone to flash floods, forest runoff, and landslides, to closely monitor official weather forecasts and disaster warnings and follow instructions from local officials.
The DDPM also encouraged the public to stay updated through official weather bulletins. Emergency assistance is available 24/7 via the department's 1784 hotline.
