JAKARTA - The Center for Meteorology, Climatology and Geophysics (BBMKG) Region III Denpasar revealed that tropical disturbances in the form of cyclonic circulation in the south of the waters of East Nusa Tenggara (NTT) affected Bali's weather, in the form of rain and strong winds, estimated on January 12-14, 2025.

"The tropical attraction supports the formation of convective clouds - rain - and the potential for strong winds," said Head of BBMKG Region III Cahyo Nugroho, ANTARA, Sunday, January 12, 2025.

Based on BMKG data on Saturday, January 11, as of 07.00 WIB, the tropical disturbance has occurred since January 10, 2025, which has a maximum speed of up to 10 knots, or up to 19 kilometers per hour with a minimum pressure of around 1,008 hektopascal (hPa).

BMKG predicts the potential for tropical disruption will become a low tropical cyclone in the next 24-72 hours.

BBMKG Region III issued an early warning in the three-day period regarding the potential for rain with moderate to heavy intensity accompanied by lightning and strong winds of short duration in most areas of Bali.

In addition, the sea wave height in the southern waters of Bali is estimated to be up to two meters.

Likewise in the waters for the crossing route in the Bali Strait and the Lombok Strait, it is estimated that the sea wave height reaches up to two meters.

Apart from being caused by tropical disturbances, Denpasar BBMKG also observed the South Oscillation El Nino index (ENSO) with a value of minus 0.83 which affected the increase in convective cloud patterns which encouraged the potential for rain.

Then, there are also wind bends that occur in the Bali region which increase the potential for rain cloud formation, with wind speeds estimated at up to 28 kilometers per hour blowing from the west-north.

Meanwhile, the sea level temperature around Bali is generally around 29-30 degrees Celsius, and the wet air mass is concentrated from the surface layer to 200 millibars or 12,000 meters.

Wind conditions and sea waves are at risk for shipping safety. Fishing boat users are asked to be aware of wind speeds of more than 15 knots (about 27 kilometers per hour) and wave heights above 1.25 meters.

Then, barge operators are advised to be vigilant when the wind is more than 16 knots and the wave height is above 1.5 meters.
