The current La Nina phenomenon that occurred in the Pacific is predicted to cause an increase in accumulated precipitation in Indonesia by 20-40%, Head of the BMKG (Meteorology, Climatology, and Geophysics Agency) Dwikorita Karnawati said.

A release by the BMKG, Saturday (17/10), stated that La Nina which occurs in the early rainy season has the potential to increase rainfall in most areas. “The impact of La Nina on rainfall in Indonesia is not uniform, both spatially and temporally, depending on the season/month, the region, and the strength of La Nina itself,” BMKG Deputy for Meteorology Guswanto stated.

In addition to the influence of monsoon wind circulation and climate anomalies in the Pacific, Guswanto said, the strengthening of rainfall in Indonesia is also affected by the spreading of the equatorial atmosphere waves from west to east in the form of MJO (Madden Julian Oscillation) and Kelvin waves, or from east to west in the form of Rossby waves.

“The results of the analysis of the latest atmospheric dynamics conditions show MJO activity over Indonesia’s territory, which is a cluster/collection of clouds with the potential for rain,” he said.

The simultaneous La Nina and MJO’s activities, the Deputy said, could significantly contribute to the formation of rain clouds in Indonesian territory. “Based on the aforementioned conditions, the BMKG predicts that in the next week there will be an increase in rainfall with heavy intensity accompanied by potential lightning and strong winds,” he said.

On 18-24 October, Guswanto said that heavy rainfall could potentially occur in Aceh, North Sumatra, West Sumatra, Riau, Jambi, Bengkulu, South Sumatra, Bangka Belitung Islands, Lampung, Banten, Jakarta Special Capital Region, West Java, Central Java, Yogyakarta Special Region, East Java, Bali, West Nusa Tenggara, West Kalimantan, North Kalimantan, East Kalimantan, Central Kalimantan, South Kalimantan, North Sulawesi, West Sulawesi, Central Sulawesi, South Sulawesi, North Maluku, West Papua, and Papua.

Therefore, the BMKG asked the public to remain vigilant and cautious over the potential impacts caused by extreme weather conditions such as floods, landslides, flash floods, puddles, strong winds, fallen trees, and slippery roads. On the latest information, he continued, the BMKG provided 24-hour weather forecast information that can be accessed through its website, social media, and application. (PR of BMKG/UN)
