"The forecast for the peak of the rainy season for southern Central Java in general still refers to the peak forecast for the rainy season released by BMKG Semarang, there has been no update for South Central Java," he said in Cilacap, Central Java (Central Java), Wednesday, January 4, which was confiscated by Antara.
