The Meteorology, Climatology and Geophysics Agency (BMKG) has warned of possible heavy downpours and thunderstorms occurring until Sunday across Greater Jakarta and has called for residents to remain vigilant of potential impacts, such as floods and landslides.
BMKG meteorology deputy head Mulyono R. Prabowo said the agency’s analysis of atmospheric dynamics indicated that monsoon activity in Asia remained high, with winds exhibiting convergence patterns from the north of Banten to Nusa Tenggara.
“This could potentially increase the growth of rain clouds in several areas of Indonesia, including Greater Jakarta,” Mulyono said in a statement received by The Jakarta Post on Wednesday.
For instance, BMKG predicted that low-intensity rain could fall on Wednesday in South Jakarta, East Jakarta and Jakarta’s satellite cities of South Tangerang in Banten and Bogor, Depok and western Bekasi in West Java. In the evening, downpours may hit Central Jakarta and North Jakarta.
For Thursday and Friday, the agency forecast potential high-intensity rainfall along with thunderstorms in the early morning in North Jakarta, Central Jakarta, West Jakarta, East Jakarta, South Jakarta, Tangerang, Bekasi and several parts of Depok and Bogor. The intensity of the rainfall will decrease between the morning and afternoon before potentially increasing again throughout the evening and overnight.
According to the BMKG, the rainfall intensity will decrease on Saturday and Sunday. Mild to moderate-intensity rainfall is expected for Bogor, Depok, South Jakarta, East Jakarta, Bekasi and Tangerang.
“There is a chance of a high tide risk in Jakarta Bay from Jan. 9 to 12, with a 0.6 meter maximum [tide] height. This might prevent river water from flowing out to sea,” Mulyono said.
Although Mulyono called for the public to be prepared for the possible impacts of heavy rainfall, such as strong winds, flash floods, landslides and slippery roads, he assured the public the forecast rainfall “will not be as extreme as the rainfall on Jan. 1.”
Jakarta experienced its worst rainfall in over a decade on New Year’s Eve, with heavy downpours hammering Greater Jakarta for hours, causing severe flooding in the capital and its satellite cities. Multiple deaths were reported and thousands of people were forced to flee their homes.
