CILACAP - The Meteorology, Climatology and Geophysics Agency (BMKG) predicts extreme weather conditions have the potential to occur in parts of the Central Java region from January 6 to 7. BMKG urges residents to be aware of the possibility of a hydrometeorological disaster.

According to the Head of the BMKG Technician Group at the Tunggul Wulung Cilacap Meteorological Station, Teguh Wardoyo, extreme weather conditions on Friday, January 6, will likely cover parts of the Cilacap, Banyumas, Purbalingga, Banjarnegara and Wonosobo Regencies.

Magelang Regency and City, Pekalongan Regency and City, Semarang City and Regency, and Boyolali, Sukoharjo, Wonogiri, Karanganyar, Sragen, Grobogan, Blora, Pati, Kudus, Temanggung, Kendal, Batang, Pemalang, Tegal, Brebes, Purworejo, Kebumen Regencies, and the surrounding area are also likely to experience extreme weather on January 6.

On January 7, extreme weather is predicted to cover Pekalongan Regency and City as well as Cilacap, Banyumas, Purbalingga, Banjarnegara, Wonosobo, Purworejo, Kebumen, Temanggung, Boyolali, Grobogan, Brebes, Tegal, Pemalang, Batang, Pati, Kudus, and surrounding areas.

"We urge the public to remain alert to the potential for extreme weather on January 6-7 2023, which has the potential to cause hydrometeorological disasters in the form of floods, flash floods, hail, landslides, strong winds, and tornadoes, especially for people who live and live in in this disaster-prone area", Teguh said as quoted by ANTARA, Thursday, January 5.

Based on the results of an analysis of atmospheric dynamics released by the BMKG Ahmad Yani Semarang Meteorological Station on Thursday, he explained, extreme weather conditions were triggered by several factors, including active Kelvin and Rossby atmospheric waves in Java which could cause wind confluence in the Central Java region.

In addition, relatively warm sea surface temperatures with an anomaly of 0.5 degrees Celsius to 2.5 degrees Celsius in the Java Sea area can increase the potential for evaporation or the addition of water vapor mass.

"Relatively high humidity and strong local lability have contributed to the formation of rain clouds in parts of Indonesia, especially Central Java", he said.

Under these conditions, Teguh said, rain with moderate to heavy intensity which can be accompanied by lightning and strong winds is likely to occur in parts of the Central Java region from January 6 to 7, 2023.
