NATUNA - Very high waves of up to 6 meters have the potential to occur in the North Natuna Sea on 3-4 April 2022. Residents around the potentially affected areas are expected to be vigilant.
This was known through early warning information released by the Meteorology, Climatology and Geophysics Agency (BMKG), Sunday, April 3.
BMKG reported that the highest wind speeds were observed in the Natuna Sea, Sulawesi Sea, the waters of Kep. Sangihe-Kep. Talaud, and the northern waters of West Papua. Waves in the higher range of 2.50-4.0 meters are likely to occur in the waters north of Kep. Anambas-Kep. Natuna, waters north of Manokwari-Biak, North Pacific Ocean Biak-Jayapura.
The BMKG explained the factors that caused the high waves, because the wind pattern in the northern part of Indonesia was dominantly moving from the northwest-northeast with wind speeds ranging from 5-25 knots, while in the southern part of Indonesia the dominant movement was from south-west with wind speeds ranging from 5-15 knots. This condition causes an opportunity to increase waves as high as 1.25-2.5 meters in the central part of the Malacca Strait, the northern waters of Sabang, the western waters of Aceh-Kep. Mentawai, waters of Enggano-Bengkulu Island, western waters of Lampung, West Indian Ocean of Sumatra, southern Lampung Bay, western-south part of the Sunda Strait, southern waters of Java-P. Sumbawa, the southern part of the Bali-Lombok-Alas Strait, the South Indian Ocean, Java-NTB.
Then potentially in the Sulawesi Sea, the northern waters of Sulawesi, the waters of Kep. Sangihe-Kep. Talaud, Bitung-Likupang waters, northern Maluku Sea, northern and eastern waters of Kep. Halmahera, Halmahera Sea, northern waters of Sorong, northern waters of Jayapura-Sarmi, North Pacific Ocean of Halmahera-West Papua, Cendrawasih Bay.
For this reason, it is necessary to pay attention to high risks to shipping safety such as fishing boats (wind speed more than 15 knots and wave height above 1.25 m), barges (wind speed more than 16 knots and wave height above 1.5 m). , ferries (wind speed more than 21 knots and wave height above 2.5 m), large size vessels such as cargo ships/cruise ships (wind speed over 27 knots and wave height above 4.0 m).
Then it is requested that people who live and work on the coast around areas that have the chance to occur high waves to stay alert.
