The agency's official website said that strong winds are expected to occur in the territorial waters of Natuna, Anambas, and the surrounding areas for the next three days.
Forecaster of BMKG in Tanjung Pinang Ardhito warned of waves of four meters in Natuna and Anambas waters.
"These waves may last for three days or even a week," said Ardhito on Wednesday, February 3.
He urged the fishermen and transportation services to be aware, stay alert, and avoid boating in such conditions.
Ardhito also warned of high waves of two meters that have been occurring in Lingga waters in recent days.
"Be aware of waves that could reach 2.5 meters to three meters in the north of Bintan," he said.
However, the Tanjungpinang-Batam waters are relatively safe, he added.
