Thailand Meteorological Department Issues Heavy Rain Warning for October 19-25

Key summary

Mr. Nutwut Daendee, Deputy Director-General of the Meteorological Department acting as Director-General, issued the fifth advisory (No. 264/2569) on October 19, 2026, at 05:00 regarding heavy to very heavy rain expected across Thailand from October 19-25, 2026. The advisory warns of continuous rainfall and localized heavy rain in the South and East regions on October 19-20, followed by increased rainfall with strong gusts in the lower Northeast, Central region (including Bangkok and surrounding areas), upper South, and parts of the East and North from October 21-25. The department attributes these conditions to a monsoon trough passing over southern Thailand, southwest monsoon winds covering the Andaman Sea, and high-pressure systems from China affecting northern regions. Wave heights are expected to exceed 3 meters in areas with thunderstorms in the Gulf of Thailand and Andaman Sea. The public is advised to avoid travel through flood-prone low-lying areas and to monitor updates via the department's website at http://www.tmd.go.th or phone lines 0-2399-4012-13 and 1182.
