27 July 2026 GMT+7Meteorological DepartmentThe Meteorological Department issued its 9th announcement warning of heavy to very heavy rain across Thailand from 27 to 30 July 2026. Heavy rain is expected in many areas, with some places experiencing very heavy rain in the north, northeast, central, east, and western southern regions. This is due to a monsoon trough passing through the north and upper northeast, combined with a fairly strong southwest monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand. The public is advised to beware of dangers from heavy to very heavy rain and accumulated rainfall that may cause flash floods and flash floods, especially in hillside areas near waterways and low-lying areas.

Winds and waves in the upper Andaman Sea are fairly strong, with waves 2-3 meters high, and waves over 3 meters high in areas with thunderstorms. The upper Gulf of Thailand and lower Andaman Sea have waves around 2 meters high, rising above 2 meters in stormy areas. Mariners in the Andaman Sea and Gulf of Thailand should navigate cautiously and avoid areas with thunderstorms. Small boats in the upper Andaman Sea should refrain from leaving shore during this period.

For safety and to minimize potential impacts, the public is urged to plan their activities and travel cautiously during this period. People should monitor announcements from the Meteorological Department and access updated information on its website.http://www.tmd.go.thOr call 0-2399-4012-13 and hotline 1182 available 24 hours a day.
