CILACAP - The Meteorology, Climatology and Geophysics Agency (BMKG) appealed to the public to be aware of extreme weather that could potentially occur in a number of areas of Central Java (Central Java) on January 23-25, 2025.

"In accordance with the information released by BMKG Stamet (Metelological Station) Ahmad Yani Semarang this morning (22/1) it was stated that currently Indonesia's territory has been observed to be atmospheric disturbances which have led to an increase in the potential for extreme weather in several areas in Central Java," said Head of the BMKG Technician Group Stamet Tunggul Wulung Cilacap Teguh Wardoyo in Cilacap, Antara, Wednesday, January 22.

In this case, based on the analysis of the latest atmospheric dynamics, it shows that cyclonic circulation in the Kalimantan region has caused the formation of air mass gathering areas and wind bends in Central Java.

In addition, the active Equatorial Rossby waves in the Java region also support the growth of convective clouds around the Central Java region, humidity in various heights tends to be wet, so that it has the potential to increase the formation of towering rain clouds to the upper layers, strong local lability that supports the convective process on a local scale observed in Central Java.

"This condition has resulted in increased growth of convective clouds or Cumulonimbus (Cb) clouds which have the potential to cause heavy rainfall accompanied by lightning and strong winds in the Central Java region," he said.

Based on the analysis of atmospheric dynamics, he continued, several areas of Central Java that need to be watched out for have the potential for moderate to heavy rain, which can be accompanied by lightning and strong winds on Thursday (23/1) covering Cilacap, Banyumas, Purbalingga, Banjarnegara, Kebumen, Purworejo, Wonosobo, Magelang Regency/City, Boyolali, Klaten, Sragen, Blora, Rembang, Grobogan, Demak, Jepara, Temanggung, Semarang Regency, Salatiga City, Kendal, Batang, Pekalongan Regency, Pemalang, Tegal Regency, Brebes and its surroundings.
