"The highest wind speeds are observed in the Flores Sea, Banda Sea, and Arafura Sea," she said in a written statement on Tuesday, February 3, 2026.
She mentioned that these conditions could lead to an increase in wave heights of 1.25-2.5 meters in the Northern Malacca Strait, western Indian Ocean of Nias Islands, western Indian Ocean of Bengkulu, northern Natuna Sea, southern Karimata Strait, central part of Java Sea, south Banten southern Indian Ocean, south Central Java Indian Ocean, south East Java Indian Ocean, south West Nusa Tenggara Indian Ocean, and the Bali Sea.
