JAKARTA The Meteorology, Climatology and Geophysics Agency (BMKG) estimates that most parts of Indonesia will experience moderate to very heavy rain in the next week, from November 29 to December 5, 2024. The public is advised to be aware of potential impacts of disasters, such as floods and landslides.

The Deputy for Meteorology of BMKG, Guswanto, explained that this weather condition was influenced by a number of atmospheric phenomena, such as Madden-Julian Oscillation (MJO) activity, Rossby and Kelvin waves, and the presence of a Negative Dipole Mode.

In addition, cyclonic circulation in several areas, including the Malacca Strait, southern waters of East Nusa Tenggara, and the waters of Halmahera, also increases the intensity of rainfall.

MJO which is currently active in phase 4 supports the formation of rain clouds in the western region of Indonesia. In addition, Rossby and Kelvin waves also strengthen the potential for rain in the western and eastern regions of Indonesia," said Guswanto.

BMKG maps areas that have the potential to experience moderate to very heavy rain during this period, including:

- Moderate to heavy rain: Aceh, North Sumatra, West Sumatra, Riau, Jambi, South Sumatra, Riau Islands, Bengkulu, Lampung, Banten, DKI Jakarta, West Java, Central Java, DI Yogyakarta, East Java, Bali, West Nusa Tenggara, East Nusa Tenggara, West Kalimantan, Central Kalimantan, North Kalimantan, East Kalimantan, North Sulawesi, Central Sulawesi, South Sulawesi, Maluku, and Papua.

- Heavy to very heavy rain: West Kalimantan.

- Strong winds: Lampung, Banten, Central Java, and East Java.

BMKG reminded the public to pay attention to the weather early warning that is issued regularly. In addition, people in areas prone to flooding or landslides are asked to prepare mitigation steps, such as securing valuables and complying with directions from the National Disaster Management Agency (BNPB).

According to BNPB guidelines, if heavy rains occur for more than 120 minutes or visibility decreases to less than 100 meters, people living around riverbanks or hill slopes must evacuate immediately. These conditions open up opportunities for hydrometeorological disasters such as flash floods, landslides, and tornadoes.

"Public vigilance is very important to minimize the impact of disasters. Always make sure to always monitor the latest information from the BMKG," said Guswanto.
