“Weak ENSO La Nina conditions indicate the potential for increased rainfall to very high (>150mm/dasarian) in parts of central and eastern Indonesia,” wrote BMKG on Instagram, Wednesday (3/12).
La Niña, which is characterized by cooling sea surface temperatures in the central-eastern Pacific, usually drives an increase in rainfall in Indonesia.
BMKG emphasized that the combination of climate factors can increase the chance of rain with high to very high intensity, especially in the central and eastern regions of Indonesia.
Head of BMKG, Teuku Faisal Fathani, explained that several areas still have the potential to experience heavy rain in the next few days.
“We invite the public to remain alert but there is no need to panic. Make sure the water channels are functioning well, keep the environment clean, and monitor weather updates via InfoBMKG before carrying out activities,” said Faisal, reported on the official BMKG website, Thursday (4/11).
Some areas that are predicted to experience additional rainfall due to La Nina include:
* West Nusa Tenggara
* East Nusa Tenggara
* Central Kalimantan section
* East Kalimantan section
* Part of South Sulawesi
* Certain Maluku areas
* Central Papua
* A small part of South Papua
Apart from La Niña, BMKG also noted that the Indian Ocean Dipole (IOD) was in a negative phase with an index of -0.36 at the end of November.
Although it is expected to return to neutral after November, this negative IOD phase is capable of pushing more water vapor supply from the Indian Ocean towards western Indonesia.As a result, a number of areas have the potential to experience an increase in rainfall above normal.
Areas affected by Negative IOD:
* A small part of Aceh
* Certain areas in West Kalimantan
* Bangka Belitung Islands
* Southern part of Banten
* Regions in West Java and Central Java
* A small part of East Java
* Almost all areas of Bali
Of the total 699 season zones (ZOM), BMKG reported that 75.3 percent of Indonesia’s territory has entered the rainy season.The rest are still in the dry season or fall into the one season zone.
BMKG said that a weak La Nina is predicted to last until early 2026. Although its effect at the peak of the rainy season will not drastically increase rainfall, the public is still asked to be alert to the potential for heavy rain, floods and other hydrometeorological disasters.
