BMKG Warns Strong Winds in Several Regions of Indonesia

Jakarta, MINA – The Head of Public Meteorology Center, Andri Ramdhani said based on BMKG observations, there is a low-pressure area in the waters west of the Philippines (potential Tropical Cyclone 91W) and in the northern Philippine Sea off Papua (potential Tropical Cyclone 92W).

Therefore, they advised the public to be aware of strong winds in several regions of Indonesia.

“To the people in areas experiencing strong winds, we urge you to remain vigilant and be prepared. Especially when driving as strong winds can cause billboards and trees to fall or dangerous materials to be blown around,” Andri said in Jakarta on Friday as reported by MINA.

The phenomenon of dry air intrusion from BBS crossing through South Sulawesi, Southeast Sulawesi, and Maluku regions, which can lift moist air ahead of the intrusion boundary, becoming warmer and more humid in central Sulawesi, Maluku, and Papua.

In general, the combination of these weather phenomena is predicted to cause significant weather potential during the period of July 18-25, 2024. This includes moderate to heavy rain accompanied by lightning and strong winds in West Sumatra, North Kalimantan, Southeast Sulawesi, Maluku , Southwest Papua, Central Papua, and the Papua Highlands.

“These conditions also have the potential to cause strong winds in Banten, West Java, NTB, NTT, West Sulawesi, South Sulawesi, Southeast Sulawesi, Maluku, West Papua, and Central Papua,” he explained. (T/RE1/P2)
