JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) reminds the public to be aware of the potential rain that surrounds most areas in the country on Monday, January 19.

BMKG weather practitioner, Selly Brilian, quoted by Antara, said that the potential for light-intensity rain was expected to rain on Medan, Pekanbaru, Jambi, Bengkulu, Bandar Lampung, Serang, Jakarta, Bandung, Tanjung Selor, Samarinda, Denpasar, Makassar, Kendari, Maluku, Gorontalo, Manado, Ternate, Sorong, Ambon, Manokwari, Nabire, Jayapura, Jayawijaya, and Merauke.

Moderate rain is potentially in Semarang City, and Surabaya. Meanwhile, heavy rain and rain accompanied by lightning are predicted to occur in Yogyakarta City, and Kupang. Furthermore, in Banda Aceh City, Padang, Tanjung Pinang, Pontianak, Palangka Raya, Banjarmasin, Palembang, Mataram, Palu is predicted to be thick clouds to fog.

According to BMKG, the combination of atmospheric dynamics is one of the factors that affect the weather conditions, following the results of meteorological monitoring, three tropical cyclones were found to have a direct and indirect impact on the potential for rain in Indonesia.

Tropical Cyclone Nokaen was recorded to have grown from Tropical Cyclone 91W since January 15, 2026. The system was observed to be around 10.3 degrees North Latitude and 128.8 degrees East Longitude in the East of the Philippines north of North Sulawesi, with a maximum wind speed of 40 knots or about 56 kilometers per hour and a minimum pressure of 1,000 hPa. In the next 48-72 hours, it is estimated that the intensity will persist at category one.

Tropical Cyclone 96S is observed to be around 15.2 degrees South Latitude and 113.0 degrees East Longitude in the Indian Ocean south of East Java, with a maximum wind speed of 15 knots or about 37 kilometers per hour and a minimum pressure of 1,002 hPa.

Tropical Cyclone 97S in the waters north of Northern Australia with wind speeds of 20 knots in the next 48-72 hours is also monitored to be a tropical cyclone with low chances.

The combination of the effects of these phenomena is expected to cause the potential for moderate to heavy rain, accompanied by lightning/thunderstorms, strong winds, including waves of more than two meters.

BMKG assesses that people are aware of such conditions that can also cause the impact of extreme weather disasters in hydro-meteorology, including floods, flash floods, tornadoes, landslides, and so on, along with the peak season of the rainy season until the end of February.
