T

he Meteorology, Climatology and Geophysics Agency (BMKG) has warned of extreme weather and heightened hydrometeorological risks in southern parts of Indonesia during the year-end holidays, raising urgency for early warnings and emergency readiness as the government anticipates surging public mobility, particularly in crowded tourist hot spots.

BMKG head Teuku Faisal Fathani said tropical cyclone seeds could emerge across several regions, including Bengkulu and Lampung in Sumatra island, Java and Bali, East and West Nusa Tenggara, as well as South and Central Papua, between the second week of December and early January. They may dissipate or intensify into full-fledged cyclones.

The agency also expects rising rainfall levels between Dec. 28 and Jan. 10, increasing the likelihood of floods and landslides. 

“These are regions vulnerable to the formation of cyclone seeds that may develop into tropical cyclones. There will also be risks of rising rainfall intensity, hydrometeorological disasters and elevated [tidal] waves,” Faisal said on Monday during a meeting with House of Representatives’ Commission V, which oversees infrastructure and transportation.

He further called all stakeholders to step up their early warning and emergency responses to achieve a “zero casualty” target.
