JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) issued an early warning for high waves of 4 to 6 meters which are likely to occur in the South Indian Ocean of Java.

In a written statement from the BMKG received in Jakarta, Thursday, September 15, it is stated that high waves have the potential to occur in several areas of Indonesian waters on September 15-17, 2022.

The BMKG explained that the wind pattern in the northern part of Indonesia is dominantly moving from Southeast-West Day with wind speeds ranging from 6-15 knots, while the southern part of Indonesia is dominantly moving from the East-Tenggara with wind speeds ranging from 10-25 knots.

The highest wind speed was observed in the southern waters of Banten and the southern Indian Ocean of Central Java.

In addition to high waves of up to 6 meters in the southern Indian Ocean of Java, based on Antara's report, this condition also causes an increase in waves as high as 1.25-2.50 meters to occur in the northern waters of Sabang Island, the western waters of Aceh, the western waters of Simeulue Island, and the West Indian Ocean of Aceh- Simeulue Islands.

In addition, there is also the opportunity to occur in the southern waters of Banjarmasin-Kotabaru, the southern Makassar Strait, the northern part of the Sawu Sea, the southern waters of Timor Island, the Manui - Kendari waters, the waters of the Wakatobi Islands, the Banda Sea, the southern waters of the Sula Islands, the northern Maluku Sea, the waters of the Kai-Aru Islands, the Arafuru Sea, the northern waters of Biak-Papua Island.

Meanwhile, in higher waves in the range of 2.50-4.0 meters, it is possible to occur in the western waters of the Mentawai Islands, the waters of Enggano- Bengkulu Island, the western waters of Lampung, the western and southern Sunda Straits, the southern Gulf of Lampung, the southern waters of Banten-East Java, the West Indian Ocean Mentawai Islands-Lampung, the southern Bali-Lombok Strait, the western Sumba Strait, the southern waters of Sumba Island, the waters of Sabu Island, the waters of Kupang-Pulau Rotte, the southern part of the Sawu Sea, the Southern Indian Ocean Bali-NTT.

The potential for high waves in some areas could pose a risk to shipping safety.

For this reason, the BMKG urges the public to always be vigilant, especially for fishermen who are active in transportation modes such as fishing boats (wind speeds of more than 15 knots and wave height above 1.25 m), Tongkang Ships (wind speeds of more than 16 knots and wave height above 1.5 m), Ferry Ships (wind speeds of more than 21 knots and wave height above 2.5 m), and large ships, such as the Cargo/Air Ship (wind speed of more than 27 knots and wave height above 4.0 m).

For people who live and work on the coast around areas where high waves are likely to occur to remain vigilant.
