It was learnt that the tidal current of the sea rose, overflowed its banks and emptied into the Koluama River.
Already, residents of the communities located along the banks of Koluama River were reportedly exposed to the direct attack of waves and tidal currents from the sea.
On Thursday traditional rulers of the communities, struck by fear, rushed to Yenagoa, the state capital, to raise the alarm over the threats by the sea to wash away the communities.
