JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) has issued an early warning regarding the possibility of high waves up to 4 meters in several Indonesian waters.

The high wave is predicted to start on Monday, January 20 at 07.00 WIB until Thursday, January 23 at 07.00 WIB.

According to BMKG data, waves with a height of between 2.5 and 4 meters have the potential to hit four territorial waters, namely the western Indian Ocean of Sumatra, the southern Indian Ocean of Banten, the South Indian Ocean of East Java to East Nusa Tenggara (NTT), and the North Natuna Sea.

In addition, the highest wind speed was observed in the northern Natuna Sea and Indian Ocean south of Java to West Nusa Tenggara (NTB).

Wind patterns in northern Indonesia are dominated by movements from Northeast to East at a speed of 6-30 knots, while in the southern region, winds move from Southwest to Northwest at a speed of 6-30 knots.

BMKG appealed to the public, especially fishermen and those who are active in water areas, to increase awareness of the threat of high waves. Anticipatory steps are very important to reduce the risk of marine accidents due to bad weather and unfavorable water conditions.
