DDPM issues flash flood alert for five Prachuap Khiri Khan districts

The Department of Disaster Prevention and Mitigation (DDPM) issued an emergency mobile alert via cellular networks on November 7, 2026, warning residents across five districts in Prachuap Khiri Khan province to remain on high alert for sudden flash floods and forest runoffs.

Emergency Alert and Affected Areas

The mobile broadcast notification targeted Kui Buri, Mueang Prachuap Khiri Khan, Thap Sakae, Bang Saphan, and Bang Saphan Noi districts. Authorities specifically highlighted high-risk zones including Khao Lan, Thap Sakae, and Huai Yang subdistricts within Thap Sakae district, where persistent heavy rain has driven accumulated water levels higher.

The DDPM collaborated with major mobile network operators, including AIS, True, and NT, to disseminate the Cell Broadcast warnings directly to mobile phones in the endangered areas. Residents have been advised to move valuable items to higher ground, take precautions against electrical hazards, relocate vehicles to safe elevated zones, and pay special attention to vulnerable groups.
