DDPM issues flood alerts for two rivers on September 29

Flood alerts were sent to riverside communities in Prachin Buri and Phetchaburi as rising water and a dam release raised overflow risks.

  • Thailand's Department of Disaster Prevention and Mitigation (DDPM) issued flood warnings for communities along the Prachin Buri and Phetchaburi rivers.
  • The alert for the Prachin Buri River was prompted by rising water levels that have already caused flooding in seven districts.
  • The Phetchaburi River warning is for Ban Laem district, where a release from the Phetchaburi Dam combined with high tide poses an overflow risk.
  • Residents in the affected areas were urged to move belongings to higher ground and prepare for potential evacuations.

Thailand’s Department of Disaster Prevention and Mitigation (DDPM) issued Cell Broadcast flood warnings on Tuesday (September 29) for riverside and low-lying communities along the Prachin Buri and Phetchaburi rivers after identifying two areas at risk of flash flooding and river overflow.

The alerts cover rising water in Prachin Buri, where homes have already been affected across seven districts, and Ban Laem district in Phetchaburi, where a dam release combined with high tide could cause the Phetchaburi River to overflow its banks.

People living along the river, in low-lying areas or other locations at risk were urged to immediately move belongings and vehicles to higher ground, secure valuables and important documents, and take precautions against electric shock.

The DDPM also advised residents to move vulnerable people to safety and evacuate to shelters immediately where necessary. Anyone requiring assistance was told to contact their kamnan, village head or community leader.

Phetchaburi Dam release raises Ban Laem overflow risk

In Phetchaburi, the DDPM warned that the Phetchaburi Dam was releasing water downstream at 93.3 cubic metres per second, increasing the risk of the Phetchaburi River overflowing in Ban Laem district.

The risk is being compounded by high tide, prompting authorities to urge people living along the Phetchaburi River and in low-lying parts of Ban Laem to closely monitor water conditions.

Residents were advised to move belongings and vehicles to higher ground, secure valuables and important documents, guard against electric shock and take care of vulnerable people.

Anyone needing assistance can contact the district chief, kamnan, village head or community leader, or call the DDPM hotline on 1784.

The DDPM, working with AIS, True and NT, also sent Cell Broadcast warnings to residents in Ban Laem about the rising water level.
