The Thai Meteorological Department forecasts heavy to very heavy rain in parts of the North and upper Northeast over the next 24 hours, with heavy rain in parts of the Central region, Eastern region and Bangkok. About 70% of Bangkok and its vicinity may see thunderstorms. Flash floods and landslides are possible near streams and low-lying areas. Sea waves of 2-3 m or more are expected in the Gulf and Andaman Sea, and small boats in the upper Andaman and upper Gulf should stay ashore. For your business: plan delivery and site work around flood-prone areas, move stock off the floor, and check that staff can get to work safely.
