The Thai Meteorological Department has issued a 24-hour forecast warning of heavy rain across 32 provinces, including popular southern destinations such as Phuket, Krabi, Trang, and Satun.

Authorities urge residents and boaters to watch for flash floods, mudslides, and hazardous sea conditions.
The Thai Meteorological Department forecasts tomorrow's weather, naming 32 provinces facing heavy rain. Bangkok has a 40% chance of thunderstorms. A warning is in effect for flash floods and mudslides on October 23, 2026. The 24-hour outlook shows heavy rain in parts of the South, while upper Thailand will see scattered thunderstorms. Residents in affected areas should beware of thunderstorms, heavy downpours, and accumulated rainfall that could trigger flash floods and mudslides in foothill and lowland areas. This is due to a weakening high-pressure system or cold air mass over upper northern and northeastern Thailand and the South China Sea, while easterly winds still cover upper Thailand, upper southern Thailand, and the upper Gulf of Thailand, combined with a monsoon trough crossing the central South. For the Andaman Sea and Gulf of Thailand, areas with thunderstorms will have waves exceeding two meters. Boaters should navigate with caution and avoid areas with thunderstorms.
