"The analysis results of the latest atmospheric dynamics conditions show that there are turns and slowdowns in wind speeds that can increase convection patterns," BMKG's deputy for meteorology, Guswanto, said here on Saturday.
Significant atmospheric dynamics that can trigger an increase in rainfall have been indicated in many parts of Indonesia, he added.
In addition, the interaction of the active Madden-Julian Oscillation (MJO) with the Equatorial Rossby waves and Kelvin waves could maximize the potential for rain cloud growth in several parts of Indonesia in the next few days.
"Based on these conditions, the BMKG has predicted rainfall of moderate-heavy intensity, accompanied by lightning and strong winds, can potentially occur on October 2–8,” Guswanto said.
The regions of West Sumatra, Bengkulu, and West Java have been put on alert for heavy rains from October 1 to 3, he informed.
It is important to check the infrastructure capacity and water resource systems, ensure environmental and waste management, prevent tree logging on slopes, and conduct greening activities to minimize the impact of heavy rainfall and extreme weather, he highlighted.
Moreover, the relevant agencies need to trim brittle tree branches, strengthen poles to keep them from collapsing during strong winds, and intensify education among the public on the mitigation of hydrometeorological disasters, such as floods, landslides, flash floods, strong winds, and high waves.
According to Guswanto, between October 2 and 8, extreme weather is likely to occur in the provinces of Aceh, North Sumatra, West Sumatra, Riau Islands, Riau, Bangka Belitung Islands, Jambi, Bengkulu, South Sumatra, Lampung, Banten, Jakarta, West Java, Central Java, Yogyakarta, East Java, and Bali.
It is also forecast to affect West Nusa Tenggara, West Kalimantan, East Kalimantan, North Kalimantan, Central Kalimantan, North Sulawesi, Central Sulawesi, West Sulawesi, South Sulawesi, Southeast Sulawesi, West Papua, and Papua.
