Heavy rainfall, thunderstorms, tidal flooding, and sea waves reaching up to four meters are expected to impact several regions across the country.
BMKG forecaster Ranti Kurniati explained in an official statement that light rain is likely in cities including Banda Aceh, Medan, Pekanbaru, Bengkulu, Serang, Jakarta, Bandung, Semarang, Surabaya, Mataram, Palangka Raya, Samarinda, Gorontalo, Makassar, Kendari, Ambon, Sorong, Manokwari, Nabire, Jayawijaya, Jayapura, and Merauke.

Meanwhile, Denpasar and Kupang are expected to experience thick clouds and fog.
Daily maximum temperatures could reach 33 degrees Celsius in several areas, including Denpasar, Mataram, Kupang, Pontianak, Samarinda, Tanjung Selor, Palangka Raya, and Banjarmasin.
BMKG also highlighted the risk of tidal flooding (banjir rob) along coastal regions such as Aceh, North Sumatra, West Sumatra, Bangka Belitung, Banten, North Jakarta, West Java, East Java, Bali, West Nusa Tenggara, North Kalimantan, South Kalimantan, and North Sulawesi.
Cyclonic Activity and Tropical Disturbance
According to Ranti, current atmospheric conditions are influenced by cyclonic circulation detected in the Indian Ocean south of West Java, the Natuna Sea, and the Pacific Ocean north of Papua. Similar patterns are observed in the waters off Lampung, East Kalimantan, and Central Papua, affecting much of Sumatra and the Java Sea.
BMKG has also identified a tropical disturbance, Tropical Cyclone Seed FINA, in the Arafura Sea south of the Tanimbar Islands. The system is expected to intensify with wind speeds reaching 60 knots (category two), creating wind convergence zones of around 25 knots across the Arafura Sea, Banda, Maluku, and Aru Islands.
