JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) issued an early warning in the form of the potential for light, moderate to heavy rain which may be accompanied by lightning and strong winds in various major cities in Indonesia on Wednesday, May 13.
Quoted by BMKG, Yuyun W's assistant explained in general that the convergence area extends in the waters of western Kalimantan Barat, South Kalimantan, Central Kalimantan to East Kalimantan, and southern Sulawesi.
This condition is able to increase the potential for rain cloud growth along the areas that are passed by convergence or confluence.
Therefore, his party estimates that several major cities will have the potential to experience moderate to heavy rain accompanied by lightning and strong winds, namely in the Tanjung Pinang, Palembang, Bandar Lampung, Pontianak, Palangkaraya, Banjarmasin, Tanjung Selor, Manado and Mamuju areas.
Meanwhile, several other major cities will experience light to moderate rain, namely the Banda Aceh, Medan, Pekanbaru, Padang, Jambi, Pangkal Pinang, Bengkulu, Serang, Tanjung Selor, Denpasar, Mataram, Makassar, Palu, Gorontalo, Kendari, Ternate, Sorong, Ambon, Manokwari, Jayapura, Jayawijaya and Merauke.
Meanwhile, the big cities that are expected to only experience cloudy conditions today are the Jakarta, Semarang, Yogyakarta, Surabaya, and Kupang areas.
Previously on Saturday, May 9, BMKG identified the presence of the Algupit Tropical Cyclone in the Pacific Ocean which triggered the potential for significant rainfall in a number of regions in Indonesia due to the formation of a convergence area and cyclonic circulation.
BMKG Praktirawan Massayu explained that the cyclone was detected in the east of the Philippines with a maximum wind speed of 40 knots and a minimum air pressure of 998 hektopascal.
Tropical Cyclone Algupit is reported to be moving in a west-northwest direction. Although its intensity tends to decrease in the next 48 hours, according to him, this system induces or low level jets in the eastern Pacific Ocean of the Philippines and forms a convergence area in the waters north of West Papua to West Papua.
