TEMPO.CO, Jakarta - The Meteorology, Climatology, and Geophysics Agency (BMKG) announced Monday that typhoon Surigae detected over the eastern parts of the Philippines would affect sea wave variations in the Pacific Ocean north of Halmahera, an island in north Maluku, and likely triggered 4-6-meter-high waves.
“We urge the public to be aware of the high waves forecasted to happen in a number of locations in Indonesian waters caused by the Surigae tropical cyclone,” said BMKG Head of Maritime Meteorology Eko Prasetyo on Monday, April 19.
The extreme waves are also expected to occur in the central and eastern parts of Sulawesi Sea, northern Morotai waters, and the Pacific Ocean north of West Papua.
Wind activities generally move from the southwest and northwest at speeds up to 5-30 knots and around 5-20 knots in the southern parts of Indonesia, which move from the east-south.
The highest wind speed is detected over the waters of Sangihe-Talaud Islands, northern parts of Maluku Sea and West Papua’s Pacific Ocean.
BMKG predicted Surigae’s position as of Monday (19:00 WIB) would be at the Pacific Ocean east of the Philippines, which is 1,300 kilometers north of Tahuna. The typhoon is expected to move away from Indonesia constantly at 4 knots. The typhoon itself is detected at 110 knots with pressures up to 905 hPa.
