The Meteorological Department forecasts more rain and heavy downpours in some areas over the next 24 hours, mainly in the upper North and the eastern Northeast. Flash floods and mountain runoff are possible near streams and low-lying land. Bangkok and vicinity have thunderstorms over about 60% of the area. Plan for delivery and travel delays, check stock stored in low areas, and keep an eye on the Andaman and Gulf seas: waves are around 2 metres, so avoid sea trips in storm zones.
