"Residents are advised to check their surroundings, secure outdoor items and avoid vulnerable areas such as under trees or near unstable structures," he said on Wednesday (3/4).

BPBD called on residents to regularly check wave forecasts on its official website bpbd.jakarta.go.id/gelombanglaut and monitor flood updates through Jakarta's flood portal banjir.jakarta.go.id. Reports of potential flooding can also be submitted via the JAKI app.
