ClLACAP - The Meteorology, Climatology and Geophysics Agency (BMKG) warns of the potential for flooding and landslides in a number of Central Java areas as the high rainfall is expected to last until the second week (10 days) of February 2026.
Head of the BMKG Data and Information Dissemination Service Working Team, Tunggul Wulung Cilacap Meteorological Station, Teguh Wardoyo, said based on the data released by the BMKG Central Java Climatology Station related to the results of monitoring the day without rain (HTH) as of January 10, 2026, most of the province's territory is still experiencing rain until the last data update.
"Some areas in the central to southern central Java are in the very short category, namely one to five days without rain. Meanwhile, several points in the Cilacap and Banyumas regions are in the short category, six to 10 days without rain," said Teguh, quoted by Antara, Monday, January 12.
Meanwhile, based on the analysis of the first daily rainfall in January 2026 (1-10 January), he said, the BMKG noted that the rainfall conditions in Central Java were generally in the medium to high category.
According to him, the eastern Central Java region was recorded in the low to medium rain category, while Jepara and Kudus regencies and most of the Demak region were in the high to very high category.
"BMKG also predicts that by the second week of January 2026, the opportunity for medium rainfall with a probability of more than 60 percent will occur in most of Central Java," he said.
However, he said, a number of regions, such as parts of Brebes, Tegal, Pemalang, Kendal, Demak, Rembang, and Grobogan, are expected to have lower medium rainfall opportunities than other regions.
In addition, he continued, the opportunity for high to very high rainfall with a probability of more than 60 percent is expected to occur throughout the Batang area and Pekalongan Regency/City, as well as parts of Pemalang, Kendal, Purbalingga, and Jepara.
Furthermore, he said that the BMKG's deterministic prediction showed that in the second and third week of January 2026, rainfall was generally in the medium to high category.
"This condition is expected to continue until the second week of February 2026, although the Rembang, Blora, and Grobogan regions tend to be in the low rainfall category," he said.
Regarding this condition, he appealed to the public and local governments to increase vigilance against the potential impact of hydrometeorological, especially floods and landslides, especially in areas with high to very high rainfall and disaster-prone areas.
"The public is expected to continue to monitor weather and climate information from BMKG and take anticipatory steps to minimize the risk of disasters," said Teguh.
