Meta Description: BMKG warns of increasing extreme weather events in Indonesia, with heavy rain, strong winds, and potential flooding.

Heavy rain with the potential for flooding and strong winds is expected in several parts of Indonesia in the coming days, according to the Indonesian Meteorology, Climatology, and Geophysics Agency (BMKG). The weather bureau attributes this to suspect areas and cyclonic circulations developing in the region.
In an official statement, BMKG revealed that there’s a heightened possibility of thunderstorms and heavy rain, gusty winds, and lightning in several regions. This is due to the presence of suspect areas in the Indian Ocean south of Bali and West Nusa Tenggara (NTB), and cyclonic circulations in the Indian Ocean west of Aceh, the Philippines Sea, and the Banda Sea.
BMKG explained that these suspect areas and cyclonic circulations create regions of slow wind speeds (convergence) and wind meeting points (confluence), leading to extreme weather conditions in various parts of Indonesia. Additionally, active atmospheric dynamics such as the ongoing weak La Niña phenomenon and Asian monsoon winds are contributing to this prognosis.
"Expect significant rain in the foreseeable future, particularly in western and eastern regions," BMKG warned on Thursday (9/1/2025). "The increased rain potential in some areas could lead to hydro-meteorological disasters like floods, landslides, and strong winds."
Extreme Weather Conditions Escalating
In a separate statement, BMKG Deputy Head for Meteorology Guswanto disclosed that Tropical Cyclone Warning Center (TCWC) Jakarta has been monitoring a low-pressure system since January 3, 2025, which started moving westward and intensified into Tropical Depression 97S off East java’s southern coast on January 7.
"Based on the latest analysis on January 9, 2025, 97S has strengthened and is now detected in the Indian Ocean’s southern Lampung region, moving south," Guswanto said. "This tropical depression is anticipated to cause indirect impacts like increased rain and gusty winds, as well as direct impacts like high waves in southern and southeastern Indonesian waters in the next three days."
Tropical Depression 97S is expected to amplify the potential for moderate to heavy rain, accompanied by gusty winds, in multiple regions, including Bengkulu, South Sumatra, Lampung, Banten, Jakarta, West Java, and Central Java. Additionally, wave heights ranging from 1.25 to 2.5 meters are predicted in Java’s southern seas, the Sundra Strait’s western and southern regions, the Indian Ocean’s southern Java to NTB, and the Indian Ocean’s west Bengkulu to Lampung.
Guswanto emphasized the necessity of anticipating these weather conditions, especially in coastal and southern Indonesian regions, as extreme weather can disrupt marine activities and affect coastal communities.
Preparing for Extreme Weather Events
BMKG urges residents to:
- Anticipate hydro-meteorological disaster risks, particularly in prone areas
- Clean drains and surroundings to minimize flood risks
- Avoid activities in prone areas and prepare emergency kits
- Monitor up-to-date weather information through official BMKG channels
- Stay calm and vigilant regarding changes in weather conditions and understand evacuation procedures if necessary
BMKG assures citizens that they will continue to monitor and update the weather situation.
