JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) said that coastal flooding or tidal flooding could hit a number of areas until early December 2023.

BMKG Deputy for Meteorology Guswanto said that the increase in the maximum sea tide height due to the perigee phenomenon, which occurs during the moon at the closest point to the earth, risks causing tidal flooding.

"The public is advised to always be vigilant and alert to anticipate the impact of the maximum tide of sea water," he said in Jakarta, Sunday.

Based on high monitoring of water levels and tidal predictions, he explained, tidal flooding has the opportunity to occur in coastal areas of North Sumatra such as Medan Belawan, Medan Marelan, and Medan Labuhan from November 23 to December 1, 2023.

In addition, tidal flooding has the opportunity to hit the coastal areas of Bandar Lampung from November 27 to December 1, 2023, the western and southern coastal areas of Banten from November 26 to 30, 2023, and the northern coastal areas of Jakarta from November 26 to December 2, 2023.

coastal areas of Central Java such as Semarang City, Demak Regency, Pekalongan Regency, Brebes Regency, Tegal City, Tegal Regency, and Pemalang Regency, according to the BMKG, face the potential for tidal flooding from 1 to 23 November 2023.

Meanwhile, in coastal areas of Maluku such as Ambon Bay, Saumlaki, Kai Islands, Dobo Islands, and eastern Seram Regency, tidal flooding has the opportunity to occur from 25 to 30 November 2023.

Guswanto said that tidal flooding could disrupt loading and unloading activities at ports, salt ponds and land fisheries businesses, as well as daily activities of coastal residents.
