The Meteorological Department forecasts 60-70% rain coverage for the north, northeast, east and central regions on 29 Aug 2026, with heavy to very heavy rain in some areas. Bangkok and the south (east coast) are at about 40%. Flash floods and flash torrents are possible near slopes and low-lying areas. For a business: move stock off ground floors, secure outdoor equipment, plan delivery routes around flood-prone roads, and expect staff or customer travel delays. In the Andaman Sea, waves reach 2-3 m and small boats should stay ashore.
