Tropical Cyclone Seed 93S
is still active and has a high chance of becoming a tropical cyclone.The impact,
high waves
up to 2.5 meters has the potential to occur in the Sunda Strait to the waters of West Sumatra.
BMKG analysis as of Monday (22/12) at 07.00 WIB stated that the seeds of this tropical cyclone were located in the Indian Ocean southwest of West Java.93S is expected to continue moving westward.

“The 93S Tropical Cyclone Seed System has a high chance of becoming a Tropical Cyclone in the next 24 hours,” wrote BMKG in its analysis, Monday (22/12).
This tropical cyclone spawn is expected to trigger high waves of 1.25-2.5 meters in several water areas in the next 24 hours, such as the waters west of Bengkulu to Lampung, the southern Sunda Strait, the waters south of Java Island, the Indian Ocean west of Mentawai to Lampung, and the Indian Ocean south of Java Island.
In another analysis, BMKG explained that Tropical Cyclone Seed 93S triggered an increase in wind speed and wave height.
The wind pattern in the northern part of Indonesia generally moves from the North to the North East with wind speeds ranging from 6-25 knots, while in the southern part of Indonesia it generally moves from the Southwest to the North West with wind speeds ranging from 8-25 knots.The highest wind speeds were observed in the South Indian Ocean from Banten to West Java.
BMKG estimates that a number of other areas have the potential to experience waves of 1.25-2.5 meters in the period 22-25 December.The following is a list of regions:
– Indian Ocean west of Aceh
– West Indian Ocean Kep.Nias
– West Indian Ocean Kep.Mentawai
– Indian Ocean west of Bengkulu
– Indian Ocean west of Lampung
– Indian Ocean south of Banten
– Indian Ocean south of West Java
– Indian Ocean south of Central Java
– South Indian Ocean IN Yogyakarta
– Indian Ocean south of East Java
– Indian Ocean south of Bali
– Indian Ocean south of NTT
– Indian Ocean south of NTB
– North Natuna Sea
– Northern Karimata Strait
– Pacific Ocean north of Maluku
– Pacific Ocean north of Papua
– Pacific Ocean north of Southwest Papua
– Pacific Ocean north of West Papua
– Maluku Sea
Head of BMKG Teuku Faisal Fathani also highlighted the dynamics of the atmosphere during the Christmas 2025 and New Year 2026 holidays.
He said atmospheric conditions had the potential to increase the intensity of rain in a number of regions in Indonesia, which could have a direct impact on transportation safety and community activities.
“This Christmas period coincides with the peak of the rainy season, so the potential for extreme weather needs to be seriously anticipated,” said Faisal in his statement, Friday (19/12).
He explained that the 2025/2026 Christmas period is in the peak phase of the rainy season in most parts of Indonesia.Based on BMKG forecasts, high to very high rainfall with an intensity reaching 300-500 mm per month is predicted to occur from December 2025 to January 2026, especially in the regions of Java, Bali, Nusa Tenggara, parts of South Sulawesi, South Papua and Kalimantan which have a rainy season that is characterized almost throughout the year.
“During this Christmas period, we face a quite complex combination of atmospheric dynamics, starting from the active Asian Monsoon, Madden-Julian Oscillation (MJO), atmospheric waves, potential cyclone seeds to tropical cyclones, as well as the influence of weak La Nina and negative Indian Ocean Dipole (IOD). This condition has the potential to increase the intensity of rain, especially in mid-December to early January,” said Faisal.
In response to this, BMKG is taking anticipatory steps such as strengthening an integrated early warning system, continuously updating weather information, and preparing for Weather Modification Operations (OMC) as part of a hydrometeorological disaster mitigation strategy.
Apart from that, BMKG also continues to carry out real-time monitoring of weather and climate developments, including potential cyclone seeds and tropical cyclones around Indonesia through the Tropical Cyclone Warning Center (TCWC) Jakarta.
