YOGYAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) reports waves with a height of 4-6 meters have the potential to occur in the waters of southern Java, especially West Java, Central Java, and the Special Region of Yogyakarta (DIY).
"Today (June 24) we have issued an early warning of high waves in line with the development of weather conditions in the southern seas of West Java and Yogyakarta," said Teguh Wardoyo, Head of the BMKG Technician Group at the Cilacap Meteorological Station of Tunggul Wulung, in Cilacap, Central Java, Friday, June 24.
He said, if the previous early warning mentioned a wave height of 4-6 meters potentially in the Indian Ocean region south of West Java to DIY, and 2.5-4 meters high in the southern waters of West Java-DIY.
Currently, BMKG estimates the potential for very high waves ranging from 4-6 meters not only in the southern Indian Ocean of West Java-DIY, but also in the southern waters of West Java-DIY.
The increase in wave height was caused by the dominant wind pattern in the southern part of Indonesia moving from the east-southeast with wind speeds ranging from 10-25 knots.
The highest wind speeds were observed in the waters of the Mentawai Islands, western waters of Lampung, western Sunda Strait, southern waters of Java, Badan Sea, Yos Sudarso waters, Merauke waters, and Arafuru Sea.
"The direction of wind movement that tends to be in the same direction as high speed can trigger high waves.
In addition, the southern waters of West Java to DIY are currently in the east wind season," said Teguh.
Regarding the early warning of high waves, he appealed to all marine service users to pay attention to the risk of high waves on shipping safety because wind speeds of more than 15 knots and wave heights above 1.25 meters pose a risk to fishing boats.
Furthermore, wind speeds of more than 16 knots and wave heights above 1.5 meters pose a risk to barges, wind speeds of more than 21 knots and wave heights above 2.5 meters pose a risk to ferries, as well as wind speeds of more than 27 knots and wave heights. above 4 meters is a risk to large size ships such as cargo ships and cruise ships.
In addition, people who live and work on the coast around areas where high waves are likely to occur are advised to remain vigilant at all times.
Meanwhile, tourists who visit the beach are advised not to bathe or play in the water, especially in coastal areas that are directly connected to the high seas because high waves can occur at any time.
