Flood Warning Issued for Nan Province as Water Moves Toward Sirikit Dam

On August 19, 2026, the Department of Disaster Prevention and Mitigation (DDPM) reported that while flood levels in Pua district are beginning to recede, the accumulated water mass is now shifting toward the Thawangpha and Wiangsa districts.

In response to the shifting flood path, the DDPM has activated the Cell Broadcast system to issue urgent warnings to residents in these areas. Authorities are advising individuals in the path of the water to prepare for potential evacuation and to move valuable belongings to higher ground immediately. The water is ultimately expected to flow toward the Sirikit Dam.

For residents and travellers currently in Nan province, this situation necessitates heightened vigilance. Local infrastructure and road accessibility may be impacted as the water moves through the region. It is essential to monitor official updates from the DDPM and local provincial authorities, as conditions can change rapidly.

At this time, the full extent of the impact on specific transport routes and the exact timeline for the water's arrival in downstream areas remain to be confirmed. Travellers are encouraged to check with local transport providers before attempting to navigate through the affected districts. Please follow all instructions provided by local emergency services to ensure personal safety.
