91S and 92S Spell Weather Troubles for Eastern Indonesia

Two Developing Cyclonic System Threaten Indonesia and Bali with Extreme Weather

The Meteorological, Climate and Geophysics Agency (BMKG) is monitoring two developing cyclone systems on the eastern and southeastern border areas of Indonesia that threaten to bring heavy rains, strong winds, and high ocean waves to Bali, West Nusa Tenggara, and East Nusa Tenggara.

Quoted by CNN Indonesia, the Deputy for Meteorology for BMKG, Mulyono Rahardi Prabowo, said: “The cyclone season to the southeast of Indonesia usually occurs in the period between November and April. This coincides with the rainy season in Indonesia with the tropical cyclones having the propensity to increase the amount of rainfall and stimulate higher wind speeds.”

The two cyclonic systems now being monitored are identified as “91S” in the Indian Ocean to the south of East Nusa Tenggara and “92S” located south of Tual, Maluku in the Arafuru Sea.

Meteorologists from BMKG say that “91S” has the greater potential to develop into a full-fledged tropic cyclone than does “92S”.

The systems are already cited as the cause of high waves measuring between 2.5 and 4.0 meters now striking the southern shores of Central Java to Nusa Tenggara Barat, including Bali.

The Southern shores of Java, Bali, Lombok Sumba, Savu, Rote, Flores, and Kai-Aru are cautioned to be prepared for large waves rushing shore over the coming week starting from January 6, 2020.

Although “91S” is expected to mature into a fully-fledge tropical cyclone, it is moving to the south and southwest to areas that are further removed from Indonesian territory.
