"The development of the weather condition in all of Indonesia currently shows significant changes in the atmosphere, which will affect the increased rainfall potential in a number of regions in Indonesia," meteorology deputy at the BMKG Guswanto explained.
The extreme weather potential is due to atmospheric conditions, which could support the formation of more extensive raincloud cover in the future, including stronger Asian monsoon activity, he said here on Wednesday.
There is also an indication of active cold weather from Asia as well as a low-pressure center in Australia's western waters. There is also a wind circulation pattern around Indonesia's territory, which has formed a convergence area.
"This condition can increase convective activities and maximize the potential growth of rainy clouds in several Indonesian regions for the next few days," Guswanto informed.
According to the impact-based forecast, regions that may need to look out for heavy rainfall on February 22–24, 2023, include parts of Banten, Jakarta, Central Java, and East Java, he said.
They also comprise South Sulawesi, West Nusa Tenggara, and East Nusa Tenggara.
Guswanto also highlighted the potential for the formation of cumulonimbus clouds with maximum spatial coverage percentage of 50–75 percent (ONCL/occasional) over the next seven days.
This is estimated to occur in the South China Sea, Sulu Sea, Philippine Sea, North Pacific Ocean, and Papua Island.
The condition may also be seen in Karimata Strait, Java Sea, Bali Sea, Flores Sea, Makassar Strait, Sulawesi Sea, Timor Sea, Indian Ocean, parts of Sumatra Island, Kalimantan Island, and Papua Island.
Meanwhile, in the next seven days, cumulonimbus clouds with spatial coverage percentage of more than 75 percent (FRQ/frequent) are expected to form in the Philippine Sea, Carpentaria Gulf, and Indian Ocean.
High waves could also potentially be seen in Indonesian waters on February 23–24, Guswanto said,
