JAKARTA - The Meteorology, Climatology, and Geophysics Agency (BMKG) has detected the emergence of three tropical cyclone seeds, namely 94W, 92S, and 98P, which trigger turns and wind deceleration and form a number of convergence areas. This condition increases the potential for significant weather in various regions of Indonesia.
Prakirawati BMKG Yuyun Wulandari explained that the tropical cyclone 94W seed was observed in the northern Pacific Ocean of Papua with a pressure of around 1,005 hektopascal. This system is moving northwest with a wind speed of 20-25 knots.
"The 94W cyclone's seeds affect atmospheric conditions in the waters north of Papua, although the potential to develop into a tropical cyclone in the next 24 hours is still relatively low," Yuyun said, Wednesday, February 4.
Meanwhile, the tropical cyclone 92S seed was observed in the southwest Indian Ocean of Lampung and was persistent or relatively stationary. This system induces a turn and wind deceleration in the Indian Ocean region to the south of Banten, although the chance of developing into a tropical cyclone is still low.
Tropical cyclone 98P was observed on the Australian mainland with a pressure of around 1,006 hektopascal and moving west at a wind speed of around 20 knots. This system also affects atmospheric dynamics on the northern coast of Australia.
BMKG noted that the three cyclone seeds simultaneously formed a convergence area in the southwest Indian Ocean of Lampung, the southern waters of Banten, the southeast waters of East Nusa Tenggara, the northern coast of Australia, and the northern Pacific Ocean of Papua.
In addition, the cyclonic circulation is also observed in the southwest Indian Ocean of Bengkulu and the west of North Sumatra which triggers wind deceleration and the accumulation of air mass in the waters of the west of North Sumatra, the land of Aceh, to the Andaman Sea.
The combination of these phenomena increases the growth of rain clouds which have the potential to cause heavy to very heavy rain in a number of areas, including Jakarta, West Java, Central Java, East Java, East Nusa Tenggara, and South Sulawesi.
BMKG also predicts that moderate to heavy rain will occur in various other areas, accompanied by the potential for lightning and strong winds. The public is urged to continue to monitor the latest weather information through the official BMKG channels and increase vigilance against the possible impacts of extreme weather, such as flooding, flooding, and falling trees.
