JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) gave an early warning to the coastal communities of Jembrana Regency, Bali, regarding the possibility of tidal flooding throughout June. This phenomenon was triggered by a large tide of sea water which was reinforced by the east wind.

The head of the BMKG Bali Climatology Station, Aminudin Al Roniri, explained that rob usually occurs during the full moon and dead moon phases, where the position of the sun, earth, and moon is in a straight line. This condition triggers stronger gravitational forces, causing higher tides than usual.

"However, the severity of the tidal wave is also influenced by other weather phenomena that occur simultaneously. For example, a few days ago, the high tide accompanied by strong easterly winds caused tidal flooding to reach residential areas," Aminudin said in the State, Jembrana, as quoted by ANTARA.

He added that the east wind is expected to consistently blow during June, especially in the southern region of Bali. This increases the risk of tidal flooding when a full moon or tilem occurs.

"Usually this extreme condition lasts one to two days before or after the full moon phase or the moon dies," he said.

In an earlier incident on Wednesday, May 28, tidal flooding hit several coastal areas of Jembrana, causing damage to dozens of houses and forcing a number of residents to evacuate.

The head of the Jembrana BPBD, I Putu Agus Artana Putra, said that his team had carried out monitoring and data collection on the impacts caused. The affected areas were quite severe, including Pa Egar Hamlet in Banyubiru Village, Ketapang Hamlet in Pengambengan Village, and Pericak Village.

"From the provisional report, Pabuhan Hamlet is the most affected area, with 32 houses submerged, two of which were severely damaged. The occupants had to be evacuated," he said.

BPBD Jembrana ensures emergency handling and assistance continue while monitoring the potential for further rob in the next few weeks.
