BANGKOK, Thailand – A nationwide weather alert has been issued by the Department of Disaster Prevention and Mitigation (DDPM) as powerful monsoon systems lead to flood risks throughout Thailand and hazardous sea conditions in six southern provinces, including Phuket. On May 19, 2026, DDPM Director-General Theerapat Kachamat reported that a robust southwest monsoon is sweeping across the Andaman Sea and the Gulf of Thailand, combined with a low-pressure area over the northern coast of Vietnam, resulting in increased rainfall and heavy downpours, particularly in the western border regions.
The disaster alert is effective from May 19 to May 21, 2026, covering 17 provinces in the north, 20 in the northeast, 25 in the central region, and 14 in the south. The coastal provinces under maritime safety monitoring for hazardous wave conditions include Ranong, Phang Nga, Phuket, Krabi, Trang, and Satun. In response, the DDPM has collaborated with local administrative units and regional disaster prevention centers to deploy emergency personnel who will monitor weather updates and flood-prone areas continuously. Disaster response resources have also been strategically positioned to facilitate rapid water drainage and immediate public assistance.
Local authorities have been instructed to keep a close watch on natural tourist sites, such as caves and waterfalls, and to close these attractions if risks become significant. Additionally, swimming is prohibited in coastal areas where warning flags will be displayed, and vessel operators are advised to exercise extreme caution or remain ashore during severe weather conditions. The public is encouraged to stay informed through official government channels, including the ‘THAI DISASTER ALERT’ application, or to report emergencies via the 1784 hotline and the ‘@1784DDPM’ Line account.
