JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) is alerting high waves of 2.5 to 4 meters in Manado, North Sulawesi.

"So the wave height is 2.5 to 4 meters," said Head of the Center for Maritime Meteorology of BMKG Eko Prasetyo in a written statement reported by Antara, Sunday, January 17.

He said the high waves were triggered by the push of ocean wave energy superposing the tidal phase.

Then, in addition to high waves in Manado, BMKG also issued an early warning of high waves of more than 6 meters in a number of waters in Indonesia which took effect from January 17 at 07.00 WIB to January 19, 2021 at 07.00 WIB.

Anambas to Natuna Islands, Java Sea, northern and southern Java waters, Sangihe Islands waters to Talaud, Sitaro Islands waters to Bitung, Halmahera Sea, North Pacific Ocean of Halmahera.

Meanwhile, the wave height of more than 6.0 meters is estimated to have the opportunity to occur in the North Natuna Sea.

BMKG calls on fishermen to be aware of the high risk of high waves for sailing safety on fishing boats with speeds of more than 15 knots and wave heights above 1.25 meters, barges with winds of more than 16 knots and wave heights of above 1.5 meters, ferries with wind speeds of more than 21 knots and wave heights above 2.5 meters, large size vessels such as cargo ships or cruise ships with wind speeds of more than 27 knots and wave heights above 4.0 meters.

BMKG asks people who live and have activities on the coast around areas that are likely to have high waves to stay alert.
