TMD Issues Final Warning for Heavy Rain, Flash Floods in South

On October 28, 2026, the Thai Meteorological Department released Announcement No. 11 (283/2569) covering heavy to very heavy rain in the South and unsettled weather in upper Thailand, effective through October 28. The South continues to see persistent rain with isolated heavy to very heavy downpours. Residents are warned of dangers from accumulated rainfall, which may cause flash floods and mudslides, especially in foothills near waterways, low-lying areas, and flood-prone zones. Meanwhile, upper Thailand — particularly the Central region including Bangkok and its vicinity, and the East — still experiences thundershowers, strong gusty winds, and isolated heavy rain. People in these areas should beware of lightning, strong winds, and avoid open fields, large trees, and unstable billboards. A low-pressure trough over the Andaman Sea, combined with easterly winds covering Thailand and the Gulf, and a high-pressure system or cold air mass from China over upper Thailand and the South China Sea, are driving the conditions. In the Andaman Sea and Gulf of Thailand, waves exceed two meters in thundershower areas. Mariners in the Gulf and Andaman should check routes, proceed with caution, and avoid sailing in thundershower zones. For safety and to reduce impacts, the public is urged to plan daily activities and travel carefully during this period and to monitor TMD announcements continuously via www.tmd.go.th or hotlines 0-2399-4012-13 and 1182, available 24 hours. This announcement, issued at 17:00 on October 28, 2026, is the final bulletin for this event.
