T
he Meteorology, Climatology and Geophysics Agency (BMKG) has warned of potential tidal flooding along the northern and southern coasts of the islands of Java, Bali and Nusa Tenggara over the next few days.
BMKG deputy of meteorology Herizal said in a written statement on Thursday that the tides could be 4 meters high in the Java Sea and exceed 4 meters along the southern coasts of Java, Bali and Nusa Tenggara between Friday and Sunday.
Herizal said the new moon, which will appear next Sunday, was one of the factors behind the high tides, along with strong and persistent east monsoon winds traveling at 25 knots or 46 kilometers per hour.
Furthermore, the agency also predicted that rain would fall on Jakarta, Cilacap in Central Java and the southern coast of Java in the next three days.

The rain could increase the level and duration of the tidal floods.
“After three days, the tide level will gradually decrease as the wind speed also decreases,” Herizal said.
He called on people who worked in ports and coastal areas to be on the lookout for signs of floods.
"Especially in beaches where the ground has low elevation, such as the northern coast of Jakarta, Pekalongan, Semarang and Demak in Central Java and the northern coast of East Java," he said.
