Heavy Rainfall and Flash Flood Warning Issued for Southern Thailand

On November 12, 2026, the Thai Meteorological Department (TMD) released its ninth announcement regarding severe weather conditions affecting Southern Thailand. Heavy to very heavy rainfall is expected to persist through November 13, 2026, raising concerns about potential flash floods and forest runoff, particularly in low-lying areas, near waterways, and in regions adjacent to hillsides.

According to the TMD, provinces expected to experience the most significant impact on November 12 include Chumphon, Surat Thani, and Nakhon Si Thammarat. Additionally, heavy rainfall is anticipated in Prachuap Khiri Khan, Phatthalung, Songkhla, Pattani, Yala, Narathiwat, Phang Nga, Phuket, Krabi, Trang, and Satun. Reports from Khaosod Online indicate that heavy rain has already been observed across three districts in Phuket.

For travelers and residents in these regions, the situation necessitates heightened caution. Flash floods can develop rapidly, potentially disrupting local transportation and outdoor activities. It is advised to monitor local news updates and follow instructions from provincial authorities. While the current forecast covers the period through November 13, with specific warnings for Prachuap Khiri Khan on that day, the full extent of the impact on infrastructure and travel routes remains to be confirmed. Individuals in affected areas should prioritize safety and avoid high-risk zones until the weather conditions stabilize.
