Reportase.one, Jakarta – Presence of two cyclone seeds tropical, 90W and 98S, respectively in the Pacific Ocean north of New Guinea and in the Arafura Sea, influencing weather forecast todayFriday April 7 2023. According to the BMKG, both have an impact on the weather in Eastern Indonesia.
The 90W Tropical Cyclone seed is said to have a maximum wind speed of 15 knots and a minimum air pressure of 1007 mb and is moving westward. This tropical storm is causing heavy or moderate rains in North Maluku, West Papua and Papua. Likewise with strong winds in North Maluku, West Papua and Papua.
Tropical Cyclone 98S was observed in the Arafura Sea with a maximum wind speed of 20 knots and a minimum air pressure of 1004 mb and moving southwest. The indirect impact of this cyclone seed adds the potential for bad weather in areas that have been affected by 90W.
More precisely, the BMKG stated that 98S caused heavy or moderate rain in NTT, Maluku, North Maluku, West Papua and Papua. Strong winds occurred in NTT, West Papua and Papua. Also causing high waves (2.5 – 4.0 meters) in the waters south of the Sermata Islands – Babar Islands, the western Arafura Sea and the eastern Aru Islands Arafura Sea. Very high waves (4.0 – 6.0 meters) in the western Arafura Sea.
Even so, according to the BMKG, the potential for Tropical Cyclones 90W and 98S seeds to grow into tropical cyclones today is in the Low category.
Apart from Cyclone Seed
Another factor affecting today’s weather, the BMKG said, is the convergence area that extends from the Mentawai Islands to Lampung, from South Sumatra to the Karimata Strait, from West Kalimantan and Malaysia to the Makassar Strait. There are also those from the southern waters of Central Kalimantan to the Makassar Strait, from Central Java to the Java Sea, from the southern waters of NTB to the western waters of South Sulawesi, in central Sulawesi, from Maluku to West Papua, in the North Pacific Ocean North Maluku – West Papua, and from Papua to Papua New Guinea.
BMKG also monitors the confluence of winds (confluence) from North Kalimantan to Gorontalo. All of these conditions can increase the growth potential of rain clouds around the seeds of tropical cyclones and along the convergence or confluence areas.
Rain Forecast Cities
BMKG estimates that rain accompanied by lightning will occur in Jambi, Surabaya, Bandar Lampung and Kupang. Moderate intensity rain is likely to occur in Serang, Bengkulu, Tanjung Pinang, Mataram, Mamuju and Medan. Several other cities such as Banda Aceh, Denpasar, Bandung, Semarang and Makassar will receive light rain.
The air temperature ranges from 20-33 degrees Celsius. The lowest temperature is in Bandung and the highest temperature is in Surabaya and Palangka Raya.
BMKG gave ‘Alert’ status for hydrometeorological disasters based on the impact of heavy rains for Central Kalimantan, Central Sulawesi, North Sulawesi, NTT and Maluku.
