Beware, Extreme Weather Potential in 32 Regions and Tidal Flooding in Northern Central Java Waters

Extreme weather is still likely to occur in 32 regions of Central Java on Thursday (26/3) and could trigger hydrometeorological disasters as well as tidal sea level rise (rob) reaching 1 metre in the northern waters, resulting in flooding in several Pantura areas. In the morning, it is generally cloudy with light rain in several Pantura regions, but entering the afternoon, evening, and night, light to moderate rain is likely to fall evenly across Central Java, with extreme weather—namely heavy rain accompanied by strong winds and lightning—potentially affecting 32 regions. Wave heights in the northern waters have subsided, although in the southern waters they still reach 1.25-2.5 metres; however, tidal sea level rise (rob) with a maximum height of 1 metre persists in the northern waters, impacting flooding in several Pantura areas of Central Java. “Be wary of flooding in several Pantura areas of Central Java due to tidal sea level rise in the northern waters from 14:00-18:00 WIB,” said BMKG Forecaster at Tanjung Emas Maritime Station Semarang, Sediyanto, on Thursday (26/3). According to Sediyanto, tidal flooding in areas such as Pekalongan, Batang, Kendal, Semarang, Demak, Jepara, and Pati will not only inundate coastal residential areas but also disrupt community activities such as transportation, loading and unloading of goods at ports, land-based aquaculture, and salt farming. BMKG Forecaster at Ahmad Yani Meteorology Station Semarang, Arif N, stated that as before, extreme weather is still likely in 32 regions of Central Java on Thursday (26/3), so residents are urged to be alert to hydrometeorological disasters like landslides, floods, and tornadoes. The potential for extreme weather in Central Java, Arif explained, occurs quite evenly in mountainous areas, highlands, Pantura, Solo Raya, and central Central Java, which could disrupt community activities, especially for motorists on return journeys. The regions with potential extreme weather, Arif continued, are Banyumas, Purbalingga, Banjarnegara, Wonosobo, Mungkid, Boyolali, Klaten, Karanganyar, Sragen, Grobogan, Blora, Rembang, Pati, Kudus, Jepara, Demak, Ungaran, Temanggung, Kendal, Batang, Kajen, Pemalang, Slawi, Brebes, Magelang, Salatiga, Semarang, Pekalongan, Tegal, Bumiayu, Majenang, and Ambarawa. “Meanwhile, other regions are likely to experience light to moderate rain, with winds blowing from the west to north at speeds of 10-30 kilometres per hour, air temperatures ranging from 18-32 degrees Celsius, and humidity levels from 60-95%,” Arif said on Thursday (26/3) morning.
