JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) detected two of the three tropical cyclone seeds that were monitored at a number of points on Monday, September 22 have the potential to affect rainfall and high sea waves in a number of parts of Indonesia in the next 24 hours.

The three atmospheric disturbance phenomena include Tropical Cyclone Seeds RAGAZA, Tropical Cyclone 92W Seeds, and Tropical Cyclone 98B Seeds whose BMKG weather satellites are currently being detected in Teluk Bengal northeast of the Indian Ocean.

BMKG Director of Public Meteorology, Andri Ramadhani explained that the RAGASA Tropical Cyclone was observed in the Philippine Sea east of Luzon Island with a maximum wind speed of 100 knots or 185 kilometers per hour and a minimum air pressure of 925 hPa.

"In the next 24 hours, the strength of Tropical Cyclone RAGASA will increase to category 5 with movements to the west away from Indonesian territory," Andri said as quoted by ANTARA, Tuesday, September 22.

Andri said that the indirect impact of RAGASA has the potential to cause moderate to heavy rain in North Kalimantan, East Kalimantan, and West Kalimantan.

Sea waves with a height of 1.25' 2.5 meters have the potential to occur in the waters of the Sangihe-Talaud Islands.

Meanwhile, Tropical Cyclone 92W was observed in the Pacific Ocean of the West northeast of Papua with a maximum wind speed of 20 knots and a minimum air pressure of 1,013 hPa.

This cyclone seeds have the potential to become tropical cyclones, still low in the next 24 72 hours and have no impact on extreme weather in Indonesia.

However, for Tropical Cyclone 98B, he said, which was observed in Teluk Bengal northeast of the Indian Ocean, has the potential to develop into a tropical cyclone and is also low in the next 24 72 hours. This cyclone bibit is moving at a maximum wind speed of 15 knots and a minimum air pressure of 1.006 hPa.

The seeds of Cyclone 98B also have the potential to trigger sea waves with similar heights in the Indian Ocean west of Aceh and the northern part of the Malacca Strait.

BMKG urges the public, especially fishermen and users or marine transportation operators to pay attention to weather forecast information and high waves to remain safe in their activities
