Heavy Rain Forecast Triggers Flood Warnings Across Northern and Northeastern Thailand

The Thai Meteorological Department forecasts continued heavy rain and thunderstorms over the next 24 hours, especially in the northern and northeastern regions. Low‑pressure systems over northern Vietnam and the southwest monsoon over the Andaman Sea are producing moderate to strong sea‑state conditions, with wave heights of 1–2 m and localized peaks above 2 m. Residents in hill and river‑valley areas are warned of sudden flash floods and rapid runoff, while mariners are advised to avoid sailing in affected zones. Similar conditions are expected in the central, eastern, and southern regions, with varying percentages of area under thunderstorm risk and comparable wave activity in the Gulf of Thailand and Andaman Sea.
