On July 12, 2025, the Thai Meteorological Department issued its weather forecast for the next 24 hours, warning of heavy rainfall in scattered areas across Thailand. Very heavy rain is expected in parts of the western central region, the east, and the western coast of the south, driven by a strong southwest monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand, combined with a low-pressure system over northern Vietnam. Residents in these areas are advised to watch for dangers from intense rainfall and accumulated precipitation, which could trigger flash floods and flash flooding, especially in foothill areas near waterways and low-lying zones.
Waves in the Andaman Sea and Gulf of Thailand are intensifying. The upper Andaman has wave heights of 2-4 meters, exceeding 4 meters in thunderstorm areas. The lower Andaman and upper Gulf of Thailand have waves of 2-3 meters, exceeding 3 meters during thunderstorms. Sailors are urged to exercise caution and avoid thunderstorm areas. Small boats in the Andaman and upper Gulf should remain ashore through July 15, 2025. Coastal residents on the western shore of the southern region should watch for dangerous waves washing ashore.
Tropical Storm Bavi currently covers Jiangsu Province in China and is expected to weaken into a depression. This storm will not enter Thailand, but those traveling to affected areas should check weather conditions beforehand.
