        "summary": "Indonesia's Meteorology, Climatology and Geophysics Agency (BMKG) has warned of high waves reaching 2.5 to 4 metres in the southern waters of Central Java, posing risks to shipping until Friday. The agency also reported that tidal flooding in northern coastal areas has subsided, though floodwaters in Pekalongan and Demak have yet to recede. Light rain is expected in several mountainous regions despite the ongoing dry season.",
        "content": "<p>The Meteorology, Climatology and Geophysics Agency (BMKG) has\nforecast potential high waves of 2.5 to 4 metres in the southern waters\nof Central Java, covering the areas of Cilacap, Kebumen and Purworejo.\nThese conditions, which pose a risk to shipping safety, are expected to\npersist until Friday (21\/8).<\/p>\n<p>Adnan Dendy, a forecaster at the BMKG Tunggul Wulung Cilacap Station,\nreminded maritime operators to increase their vigilance. \u201cBe alert to\nhigh waves in these southern waters, which are quite risky for shipping\nactivities such as fishing boats and barges when wind speeds exceed 15\nknots,\u201d said Adnan Dendy.<\/p>\n<p>Meanwhile, different conditions prevail in the northern waters of\nCentral Java. Retna Swasti Karini, a forecaster at the BMKG Tanjung Emas\nSemarang Maritime Station, said wave heights range from 1.25 to 2.5\nmetres at several points, including the western and eastern parts of\nKarimunjawa, Jepara and Pati-Rembang. Other northern waters range from\n0.5 to 1.25 metres.<\/p>\n<p>Retna added that the tidal flooding phenomenon in the northern waters\nhas subsided, with a maximum height of 0.8 metres recorded between 05.00\nand 06.00 WIB. However, floodwaters in coastal areas along the northern\ncoast, such as Pekalongan and Demak, have yet to show signs of\nreceding.<\/p>\n<p>Wind patterns in the eastern part of Central Java are blowing from\nthe northeast to the southeast at speeds of 2 to 20 knots. These\nconditions are considered risky for fishing boats when wind speeds\nexceed 15 knots, and for barges when winds exceed 16 knots.<\/p>\n<p>On the other hand, BMKG has also noted the potential for rain in\nseveral inland areas. Agus Triyono, a forecaster at the BMKG Ahmad Yani\nSemarang Meteorological Station, said that although the dry season is\nstill ongoing, light rain is likely to fall in six areas, particularly\nin mountainous and highland regions.<\/p>\n<p>Weather from morning to midday is generally clear to cloudy. However,\nfrom late afternoon to early evening, light rain is forecast in\nPurbalingga, Banjarnegara, Wonosobo, Kajen, Slawi and Bumiayu. This\nphenomenon has also made air temperatures in these areas slightly\nwarmer. Meanwhile, other areas in Central Java are predicted to be clear\nto cloudy throughout the day.<\/p>\n<p>In general, winds are blowing from the east to the south at speeds of\n10 to 35 kilometres per hour. Air temperatures range from 16 to 34\ndegrees Celsius with humidity of 45 to 95 percent.<\/p>\n<p>\u201cBe alert to strong winds as well as forest and land fires,\u201d urged\nAgus Triyono.<\/p>",
