The Meteorology, Climatology and Geophysics Agency (BMKG) issued flood warnings on Tuesday for four of Java’s six provinces -- Banten, West Java, Central Java and East Java -- effective until Thursday. The provinces have been put on siaga (watch) status, the second-highest level of the country's four-tiered alert system. Jakarta and Yogyakarta remain at the third-highest status, waspada (advisory).

“According to the forecast from climatologists, February is the peak of the rainy season for Java Island,” BMKG weather forecaster Nanda Alfuadi said as quoted by kompas.com.

Jakartans are advised to brace for floods as the Katulampa Dam in Bogor, West Java, saw its water level rise to 120 centimeters since Sunday morning. Indonesia's capital and its surrounding areas -- especially the Puncak area and Bogor -- have seen torrential rain since last week. People living near the Ciliwung River are advised to be vigilant in light of potential flooding.

Jakarta Water Agency secretary Dudi Gardesi said the city had allocated more funds for flood control this year at about Rp 3 trillion (US$214 million), up from Rp 2.5 trillion last year, when the COVID-19 pandemic forced the city to delay the construction of some projects related to flood mitigation.

"We received less funding last year as the economy contracted due to COVID-19 pandemic," Dudi told The Jakarta Post recently. "Most of the budget this year will be used to finish the programs that were delayed last year, such as land procurement for river restoration and projects to build more water pump stations and reservoirs."
