The Thai Meteorological Department issued its sixth warning on Typhoon Maysak on July 4, 2025 at 11:00 AM. At 10:00 AM that day, Tropical Storm Maysak was positioned in the upper South China Sea, 150 kilometers south of Nanning, China (20.2°N, 107.9°E), with maximum wind speeds near the center of approximately 74 kilometers per hour. The storm was moving northward with a slight westward drift at 15 kilometers per hour and is forecast to make landfall near Nanning in southern China on July 5. The storm's center will not enter Thailand, but its indirect effects combined with a monsoon trough and the strong southwest monsoon will impact the Andaman Sea, Thailand, and the Gulf of Thailand.
Thailand will experience heavy to very heavy rainfall in some areas, particularly in the northern, upper northeastern, eastern, and southern regions. From July 5-6, the upper northern and upper northeastern regions will continue experiencing heavy to very heavy rain in some areas. Sea conditions will intensify: the upper Andaman Sea will see waves 2-3 meters high, exceeding 3 meters in thunderstorm areas; the lower Andaman Sea and upper Gulf of Thailand will have waves around 2 meters, exceeding 2 meters during thunderstorms.
Fishermen are urged to exercise caution and avoid areas with thunderstorms. Small vessels in the upper Andaman Sea should remain ashore during this period.
