JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) through the Tropical Cyclone Warning Center (TCWC) Jakarta is monitoring the development of three potential tropical cyclone seeds that have an impact on the weather in Indonesia.

Deputy for Meteorology, Guswanto explained that there are three potential tropical cyclone seeds in the territory of Indonesia that will have an impact on the weather in the next 24 hours, including Cyclone 91 B, potential cyclone seeds in the Indian Ocean southwest of Bengkulu, and potential cyclone seeds in the Timor Sea, Nusa East Southeast.

Guswanto explained that Cyclone Seedling 91B was observed around West Aceh starting today, with its exact position at 5.8 North Latitude and 90.2 East Longitude, maximum wind speed around the system reaching 20 knots (36 km/hour) and minimum air pressure at its center reaching 1003.8 hPa. Meanwhile, the movement of the 91B system is moving north to northeast.

The indirect impact in the next 24 hours from the presence of tropical cyclone 91B on weather conditions in Indonesia is moderate to heavy rain which can be accompanied by strong winds in several provinces, namely Aceh, North Sumatra, West Sumatra, and Riau.

Then, the wave height is 1.25 - 2.5 meters (Moderate) in the eastern waters of the Simeulue Islands to the Mentawai Islands, the waters of Enggano Island – Bengkulu, the western waters of Lampung, the western Indian Ocean of Lampung.

Furthermore, the wave height is 2.5 - 4.0 meters (Rough Sea) in the northern waters of Sabang Island, West Aceh waters to the Mentawai Islands, West Indian Ocean Bengkulu. Then the wave height is 4.0 - 6.0 meters (Very Rough Sea) in the Indian Ocean west of Aceh to the Mentawai Islands

The second is the potential of Cyclone Seeds in the Indian Ocean southwest of Bengkulu. It was also observed that there were suspected areas or potential cyclone seeds growing around the Indian Ocean southwest of Bengkulu. The potential for cyclone seeds in the next 24 hours is still in the low category with relatively persistent system movement.

Suspected areas in the Indian Ocean southwest of Bengkulu could have an indirect impact on the weather in Indonesia in the next 24 hours in the form of moderate-heavy rain which can be accompanied by strong winds in several areas in Bengkulu province.

It has an impact on wave heights of 1.25 - 2.5 meters (Moderate) in the eastern waters of the Simeulue Islands to the Mentawai Islands, the waters of the Enggano Island – Bengkulu, the western waters of Lampung, and the western Indian Ocean of Lampung, and causes a wave height of 2.5 - 4 0.0 meters (Rough Sea) in the Indian Ocean west of Bengkulu.

Lastly, the potential for Cyclone Seeds in the Timor Sea, East Nusa Tenggara. It was also observed that there were suspected areas or potential cyclone seeds growing around the Timor Sea, East Nusa Tenggara. Opportunities for suspected areas in the next 24 hours are in the low category, with the direction of movement to the west away from Indonesian territory.

Suspected areas in the Timor Sea may have an indirect impact on the weather in Indonesia in the next 24 hours in the form of moderate-heavy rain which can be accompanied by strong winds in several areas in the province of East Nusa Tenggara.

The wave height is 1.25 – 2.5 meters (Moderate Sea) in the western part of the Arafuru Sea, the southern waters of the Timor Island, the southern waters of the Sumba Island. Wave height 2.5 – 4.0 meters (Rough Sea) in the Timor Sea, Kupang Waters - P.Rotte.

The potential for swell waves to cause coastal flooding in the southern waters of P.Timor, the waters and the coast of Kupang-P.Rotte.

"BMKG through the Jakarta TCWC continues to monitor the development of the potential for tropical cyclones," said Guswanto as quoted by Antara, Thursday, March 17.

Regarding the potential for extreme weather, the public is advised to avoid shipping activities in the affected waters, to avoid areas prone to disasters, such as river valleys, slopes prone to landslides, trees that fall easily, beaches, and others.

In addition, be aware of potential impacts, such as flooding/flash/coastal flooding, landslides and flash floods, especially in vulnerable areas. Policy makers related to disasters to continue to increase awareness and coordination with other related parties.
