Reportase.one, Jakarta – The latest BMKG analysis on Saturday, April 8, 2023, shows an increase in seed intensity Tropical Cyclone The 98S is fast since the last 48 hours. Growing in the south of the Arafura Sea on April 6, the tropical storm is now in the vicinity of the Timor Sea, southwest of Saumlaki and is in the area of responsibility of the Jakarta Tropical Cyclone Warning Center (TCWC).
The cyclone seed is monitored to move southwest with a maximum wind speed of 35 knots and a minimum air pressure of 996 mb. BMKG estimates that the potential is high to develop into a tropical cyclone in the next 24-36 hours starting from Saturday.
Also during that period, the BMKG warned that cyclone 98S could have an indirect impact in the form of moderate to very heavy rain in West Nusa Tenggara (NTB), East Nusa Tenggara (NTT), Maluku and Papua. Strong winds in NTT, Maluku and Papua. Also high waves of 2.5 – 4.0 meters in the waters of the Sermata – Letti – Babar Islands and the western Arafura Sea.
“For NTT April 9 to 11, Standby for West Manggarai District, Kupang, Kupang City, Southwest Sumba, Sikka and Ende,” said BMKG Head Dwikorita Karnawati in a special press conference to anticipate the impact of increasing the intensity of cyclone 98S and 90W seeds in Indonesia it, Saturday.
Heavy rains in the NTT region are predicted to have impacts such as landslides, soil erosion, rock fall, flooding and river overflows. “So you have to be aware of that,” said Dwikorita, who even said the alert had reached areas in Bali April 10-11 2023.
Meanwhile, for the 90W Tropical Cyclone seed, the BMKG said it was still showing its existence around the Pacific Ocean region north of Papua. The movement of the cyclone seeds north of 98S is said to be within the responsibility area of the RSMC Tokyo (Japan).
Beyond the 98S Cyclone Seed
For predictions of today’s weather, Sunday April 9 2023, the BMKG is also monitoring cyclonic circulation in the Indian Ocean southwest of Banten and the Indian Ocean west of North Sumatra. Both of them form a meeting area and wind speed deceleration (convergence) extending from the Indian Ocean southwest of Banten to the southern waters of Central Java and from the western Indian Ocean to North Sumatra to Aceh.
Other convergence areas were observed extending from the Malacca Strait to North Sumatra, from Bengkulu to the Java Sea north of West Java, from the Babel Islands to the southern waters of Central Kalimantan, and from the southern waters of East Java to West Nusa Tenggara.
Also from Sabah to North Kalimantan, from the Makassar Strait to Southeast Sulawesi, from the Maluku Sea to the Seram Sea, from the Banda Sea to southern Papua, and from Cenderawasih Bay to central Papua.
Meanwhile, the confluence of winds (confluence) was observed from the Java Sea to the Flores Sea, from East Java to NTT. Just like convergence, confluence can increase the growth potential of rain clouds.
Today’s Rain Prediction
Rain accompanied by lightning is expected in Jambi, Banjarmasin, Pangkal Pinang and Kupang. Rain with moderate intensity is likely to occur in Bengkulu, Bandar Lampung, Ambon and Palembang.
The air temperature ranges from 17-33 degrees Celsius with the lowest temperature in Bandung. The highest temperatures are in Banda Aceh, Denpasar, Serang, Gorontalo, Surabaya and Medan.
