The Meteorology, Climatology and Geophysics Agency (BMKG) has forecast that the coastal area in North Jakarta will see tidal floods during the supermoon, expected to appear later this month.
BMKG information subdivision head Hary Tirto Djatmiko said on Friday that the upcoming perigee full moon, expected to appear on Jan. 30 to 31,
would be 14 percent bigger and 30 percent brighter than the previous phenomena, appearing on Jan. 1 and Dec. 3 last year.
“Residents living in coastal areas, particularly in Jakarta, should be cautious as tidal floods are expected between Jan. 28 and Feb. 3,” Hary said as quoted by tribunnews.com. He added that a tidal flood in Tanjung Priok, North Jakarta, was likely to occur during daylight hours.
The floods are also predicted to hit Pontianak, West Kalimantan.
According to NASA, a supermoon is a full moon that is at its closest point to Earth.
The final episode of the supermoon tetralogy will be the second full moon in a month. The phenomenon is called a blue moon, which is said to happen every two and a half years on average.
