Central Java - The Meteorology, Climatology and Geophysics Agency (BMKG) appealed to residents in the southern part of Central Java and the mountains to be aware of the potential for hydrometeorological disasters in line with the arrival of the 2022-2023 rainy season.
"Based on the weather forecast issued by the Semarang Climatology Station BMKG, the beginning of the 2022-2023 rainy season in the Central Java region is generally predicted to advance or one to three bases faster than normal," said Head of the BMKG Technician Group of Meteorological Station Tunggul Wulung Cilacap, Teguh Wardoyo, in Cilacap, Central Java, quoted from Antara, Wednesday, September 14.
Thus, he said, several areas of southern Central Java and Central Java mountains early entered the beginning of the rainy season which took place starting from the first base of September 2022.
He said the southern Central Java region that entered the beginning of the rainy season on the first basis of September was the northwestern region of Cilacap Regency, while in the central mountains of Central Java it covered Purbalingga, Banjarnegara, and Wonosobo in the north.
He said the peak of the rainy season for 2022-2023 is predicted in January and February 2023, while the nature of rain is generally predicted to be normal.
"The Central Java area which is predicted to experience the longest rainy season in 2022-2023 is part of the southern region of Cilacap Regency because it reaches 27 bases or approximately nine months," he said.
Teguh said the forecast was based on the results of data processing and analysis as well as paying attention to the development of regional and global atmospheric dynamics and the ongoing trend that could affect climate conditions in Central Java.
In this case, he continued, ENSO or El Nino Southern Oscillation showed that La Nina was weak until the end of 2022 and was predicted to gradually advance to neutral in the period February to April 2023.
In addition, he continued, the IOD or Indian Ocean Dipole showed a negative condition until the end of 2022 and the sea surface temperature (Sea Surface Temperature/SST) of Indonesia was forecasted to be warm until November 2022.
"Regarding the weather forecast, we urge the public to be aware of potential hydrometeorological disasters such as floods, landslides, moving soils, and so on, especially in areas prone to these disasters," he said.
