The Thai Meteorological Department issued a weather forecast for the next 24 hours warning of thunderstorms and heavy rainfall in some areas of Thailand's southern west coast, driven by moderate strength southwest monsoons covering the Andaman Sea, Thailand, and the Gulf of Thailand.

Wave conditions in the Andaman Sea and Gulf of Thailand are moderate, with the upper Andaman Sea experiencing waves of approximately 2 meters, while the lower Andaman Sea and upper Gulf of Thailand have waves of 1-2 meters. Thunderstorm areas may see waves exceeding 2 meters, and boat operators are advised to navigate carefully and avoid thunderstorm zones. From May 28-29, the southern region expects increased rainfall with heavy to very heavy precipitation in many areas, primarily along the west coast, as the southwest monsoon intensifies. The upper Andaman Sea will experience waves of 2-3 meters, with thunderstorm areas seeing waves exceeding 3 meters. Detailed 24-hour forecasts include thunderstorms in 30-40% of northern, northeastern, central, and eastern regions with temperatures ranging from 22-27°C low to 36-39°C high and southwest winds at 10-35 km/h.
