One source

The Thai Meteorological Department has issued its 13th weather warning, forecasting heavy to very heavy rainfall across most of the country through July 30, 2026.

According to a report by Khaosod Online Thailand on July 29, 2026, the Thai Meteorological Department (TMD) has released its 13th weather warning regarding severe conditions. A monsoon trough currently passing through the upper northern and northeastern regions, combined with a relatively strong southwest monsoon over the Andaman Sea and the Gulf of Thailand, is expected to bring significant precipitation.

For the 24-hour period ending at 6:00 PM on July 30, 2026, the TMD forecasts heavy to very heavy rain in the Northeast, East, and South. The North, Central region, and the Bangkok metropolitan area are also expected to experience heavy rainfall in some areas. Specifically, the Northeast faces an 80% chance of thunderstorms, with very heavy rain anticipated in provinces such as Nong Khai, Bueng Kan, Kalasin, and Ubon Ratchathani. The North and Central regions are forecasted to have a 70% chance of thunderstorms.

For residents and travelers, these conditions may lead to localized flooding or travel disruptions in affected provinces. It is advisable to monitor local weather updates closely, as the TMD indicates this period of intense weather is expected to continue through tomorrow. While the current forecast provides a detailed outlook for the next 24 hours, further updates from the TMD will be necessary to confirm if weather patterns will stabilize or if additional warnings will be issued beyond the current timeframe.
