JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) has issued an early warning regarding the potential for heavy to very heavy rain that is expected to hit a number of regions in Indonesia on Thursday, April 30, 2026.

Fluctuating atmospheric dynamics are the main trigger for these extreme weather conditions, so the public is urged to increase their readiness for the potential impacts.

BMKG Praktirawan, Ina Indah H, explained that the areas that need extra attention include Central Java, Yogyakarta, East Java, West Nusa Tenggara (NTB), East Nusa Tenggara (NTT), West Sulawesi, Central Sulawesi, and Maluku.

"For western Indonesia, it is necessary to be aware that there is the potential for lightning in Banjarmasin and Tanjung Selor, then the potential for moderate rain in Padang, Semarang, and Yogyakarta," said Ina in an official statement in Jakarta.

In addition to these areas, BMKG also maps the potential for light rain in a number of other major cities such as Medan, Jakarta, Bandung, Surabaya, to Samarinda.

Meanwhile, Banda Aceh is expected to be covered by thick clouds throughout the day. This condition shows that the distribution of rainfall is still quite even in the western and central regions of Indonesia despite the varying intensity.

Turning to the eastern part of Indonesia, Ina reminded of the potential for quite strong lightning rain in Ambon, as well as rain with moderate intensity in Denpasar, Mataram, Mamuju, and Nabire.

Meanwhile, cities such as Makassar, Kendari, Ternate, to Jayapura are predicted to only experience light rain. On the other hand, Kupang and Manado are observed to have the potential for thick clouds.

The BMKG continues to encourage the public to update weather information periodically through official channels to anticipate sudden atmospheric changes.

Self-preparedness, especially in areas that are included in the map of heavy rain potential, is the main key to minimizing the risk of hydrometeorological disasters such as floods and landslides.
