DENPASAR - Center for Meteorology, Climatology and Geophysics (BBMKG) Region III Denpasar asked the public to be aware of extreme weather in Bali due to the emergence of Tropical Cyclone Seeds 93S on 11-18 December 2025.
"We urge you to always be vigilant and be able to take anticipatory steps so that daily activities can run smoothly and safely," said Head of BBMKG Region III Cahyo Nugroho in Denpasar, Thursday, December 11.
BMKG identified significant developments in atmospheric dynamics that have the potential to increase rainfall intensity in most parts of Bali during this estimated period.
Based on the analysis of atmospheric dynamics, he said, BBMKG Region III said the tropical cyclone seeds were observed in the southern Indian Ocean of West Nusa Tenggara (NTB) Province.
As a result, he continued, there was a meeting of air masses and wind bends in Bali.
The cyclone seeds are also supported by the active Rosby Ekuator wave and low frequency waves around the system, weak wind speed changes (wind shear), and vorticity (twisted) in the moderate to medium category.
With conditions for meeting air masses around the system, he continued, areas in Bali are predicted to experience increased water vapor, growth of rain-causing clouds, and increased wind speed and high waves.
Reported by ANTARA, his party has mapped areas that have the potential to be affected by rain with moderate to heavy intensity and strong winds in Badung, Denpasar, Tabanan, Jembrana, Bangli, Gianyar, Karangasem, Klungkung, and Buleleng Regencies.
The area has the potential to be affected by floods, flash floods, and landslides, depending on the level of vulnerability of each region.
In addition, Cahyo also reminded to be aware of the potential for sea waves to range from 1.25 to 2.5 meters for the southern part of the Bali Strait, the Badung Strait, the southern part of the Lombok Strait, and the southern waters of Bali.
