The Meteorology, Climatology and Geophysics Agency (BMKG) issued an early warning on Thursday for sea transportation service providers and fishermen about high waves in the waters off Lombok and Sumbawa islands in West Nusa Tenggara (NTB).

Lombok International Airport Meteorology Station official Agastya Ardha Chandra Dewi said the high waves formed as a result of the formation of two tropical storms in the South China Sea, namely Son-tinh south of Hong Kong and Ampil in the east of the Philippines.

Low atmospheric pressure in the Arafura Sea and the waters off western Australia also contributed to the formation of the high waves.

“Average wind velocity can reach 35 kilometers per hour. It caused the waves in waters around NTB to be included in the dangerous category as they can reach up to 5 meters high in some areas, such as in the southern part of Lombok Strait,” Agastya said.

Waves 1.25 m and higher are considered dangerous for small fishing boats and tongkang boats, while waves more than 4 meters high can also pose risks to ferries.

The BMKG forecast the high waves will continue until Saturday.

The weather conditions have disrupted fast boat services from Bali to the three Gili islands in Lombok, namely Trawangan, Air and Meno, since Tuesday, prompting authorities to temporarily stop the service.

“Many tourists use the ferry crossing from Lembar port [in West Lombok],” said Any Hainury, the manager of Bella Trawangan Villa. (swd)
