Alert: BMKG Warns of Heavy Rainfall Across Multiple Regions Due to Ex-Tropical Cyclone Nuri
Indonesia’s Meteorological, Climatological and Geophysical Agency (BMKG) has issued an early warning regarding the potential for heavy to very heavy rainfall across several Indonesian regions. The situation is driven by the influence of ex-tropical cyclone Nuri and other regional atmospheric activities.
BMKG forecaster Nazmi explained that ex-tropical cyclone Nuri is currently being monitored in the northern Pacific Ocean above Papua. The system is moving in an easterly to north-easterly direction with maximum wind speeds reaching 25 knots.
The presence of this ex-cyclone is inducing the formation of convergence and confluence zones north of Papua. These conditions directly increase the potential for rainfall cloud development in surrounding areas. Additionally, BMKG is monitoring a low-pressure system in northern Australia.
The phenomenon in Australia is triggering lower-level wind flow, or low-level jet, from the Arafura Sea to Australia’s northern coastline, impacting rainfall cloud formation across eastern Indonesia, particularly south of Timor Island.
Based on atmospheric data analysis, BMKG forecasts that heavy to very heavy rainfall potential will be concentrated in the following regions.
Apart from these areas, several major cities are also predicted to experience extreme weather in the form of rainfall accompanied by lightning or thunder.
Meanwhile, light rainfall is forecast to fall on major cities including Banda Aceh, Medan, Pekanbaru, Padang, Palembang, Semarang, Yogyakarta, Surabaya and Jayapura.
For the regions of Serang, Jakarta and Pontianak, weather conditions are predicted to be generally cloudy. For the Bandung region, BMKG forecasts hazy air conditions during the same period.
Overall, the capital’s sky will be dominated by clear to partly cloudy conditions, though the potential for light rainfall remains in some areas during the afternoon.
BMKG reminds the public to remain vigilant towards extreme weather potential in the capital region over the coming week, whilst the Regional Disaster Management Agency (BPBD) of DKI Jakarta has urged residents to prepare for potential extreme weather impacts.
