Heavy Rain Submerges Four Districts in West Nias Under Floodwaters

Heavy rainfall that battered West Nias Regency, North Sumatra, on Sunday (6/9) caused the Lahomi River and the Moro’o River to overflow. As a result, four districts were submerged under floodwaters reaching depths of around 100 centimetres.

Sri Wahyuni Pancasilawati, Head of Emergency Management, Equipment and Logistics at the North Sumatra Regional Disaster Management Agency (BPBD), said the four flooded districts were Lahomi, Mandrehe, West Mandrehe and Sirombu.

“The flooding occurred on Sunday, 6 September 2026 due to high-intensity rainfall in West Nias Regency. The water levels of the Lahomi and Moro’o rivers overflowed and caused flooding in several areas,” she said on Monday (7/9).

She noted that the flood submerged a number of residents’ homes. Beyond residential areas, the floodwaters also damaged community farmland, including rice paddies and irrigation networks.

“Roads used by residents at several points also suffered damage due to the flooding. These conditions have the potential to disrupt residents’ activities, particularly in areas affected by inundation and infrastructure damage,” she explained.

According to preliminary data, she said, there were no fatalities or injuries resulting from the incident. The BPBD also reported that no residents had been evacuated so far.

“The West Nias Regency Government, through the BPBD, has conducted assessments and surveys at a number of flood-affected locations. Officers are also coordinating with communities and relevant parties to determine the latest conditions and the handling needs on the ground,” she said.

Meanwhile, the North Sumatra Provincial BPBD continues to coordinate with the West Nias Regency BPBD on disaster response, including monitoring developments in the affected areas.

“As of Monday (7/9), the West Nias Regency BPBD is still carrying out monitoring and response efforts in accordance with conditions on the ground. We urge residents in areas potentially at risk to remain vigilant, as high-intensity rainfall could still raise river levels and cause the flooding to spread further,” she stated.
