JAKARTA The Meteorology, Climatology and Geophysics Agency (BMKG) estimates that a number of major cities in Indonesia will experience light to heavy rain accompanied by lightning on Friday, June 20. The public is advised to be aware of the potential for extreme weather.

"Light rain is likely to occur in most parts of Indonesia, such as Palembang, Lampung, Bandung, Surabaya, Denpasar, Makassar, to Jayapura," said BMKG Prakirawati Ranti Kurniati, quoted by ANTARA, Friday morning.

Rain with moderate intensity is expected to fall in the cities of Medan, Manado, and Sorong. Meanwhile, heavy rain accompanied by lightning has the potential to flush Jakarta, Banjarmasin, Mamuju, and Palu.

In addition, a number of cities such as Banda Aceh, Padang, Yogyakarta, Kupang, and Pontianak are forecasted to be thick or foggy cloudy throughout the day, with temperatures ranging from 25 to 30 degrees Celsius.

The BMKG explained that this condition was influenced by atmospheric dynamics including the transition phase to the dry season, as well as the presence of Tropical Cyclone 97S Seeds in the southwest of Banten which triggered the growth of rain clouds and strong winds.

"This condition also increases sea waves of 2.5'4 meters in the Indian Ocean west of Aceh to the south of East Java," said Ranti.

BMKG also reminded the potential for ROB flooding on the coasts of Central Java, South Kalimantan, Central Kalimantan, and Maluku.

The public is asked to remain vigilant and monitor the update of official weather information from the BMKG.
