Thai Meteorological Department Issues Heavy Rain Warning for 43 Provinces

The Thai Meteorological Department (TMD) has released its sixth official announcement (No. 222/2569) regarding severe weather conditions across Thailand. According to the report published by Thai Post on September 24, 2026, 43 provinces are currently under a warning for heavy to very heavy rainfall expected within the next 24 hours.

This weather alert is part of a broader advisory that remains in effect until September 27, 2026. The TMD advises residents and travelers in the affected regions to remain vigilant against potential flash floods and runoff, particularly in low-lying areas or near waterways.

For those currently traveling or residing in Thailand, it is essential to monitor local weather updates closely, as conditions can change rapidly during the monsoon season. Travelers should check their specific routes for potential disruptions to transport or outdoor activities. While the TMD has identified the scope of the affected areas, specific localized impacts—such as road closures or flight delays—remain subject to confirmation by local authorities. It is recommended to follow official government channels for real-time safety instructions and to exercise caution when navigating areas prone to heavy water accumulation.
