BMKG asks DIY residents to be aware of extreme weather due to 90S cyclone seeds

JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) asked the public to be aware of the potential for extreme weather in the form of moderate to heavy rain accompanied by strong winds in the Yogyakarta Special Region (DIY) due to the influence of the 90S cyclone seed in the Indian Ocean.

Acting Head of the Yogyakarta Meteorological Station Sandy Purba Almubarak said that the cyclone's seeds were predicted to be active until March 8, 2026.

"The 90S cyclone seeds cause wind convergence and wind turning in the region along the island of Java. This condition supports the growth of rain clouds in most parts of the island of Java, including DIY," said Sandy as quoted by ANTARA, Thursday, March 5.

According to him, based on BMKG's predictions, in the next 24 hours the intensity of the 90S cyclone seed is expected to begin to decrease, which is marked by wind speeds of around 35 knots or 65 kilometers per hour and the air pressure increases to 998 hPa.

"Furthermore, in the next 48 hours, this cyclone seed is expected to continue to weaken with wind speeds of around 30 knots or 55 kilometers per hour, and in the next 72 hours it is expected to disappear," he said.

Sandy said the results of atmospheric dynamics analysis also showed that the sea surface temperature in the Java Sea and the Indian Ocean south of Java was relatively warm, ranging from 26 to 29 degrees Celsius which supported an increase in the supply of water vapor to the atmosphere.

In addition, the vertical profile of air humidity in the DIY region at an altitude of 1.0 to 3.0 kilometers or at the 850-700 millibar layer was recorded between 60 and 95 percent, so it quite affects the chances of rain cloud growth in the region.

On March 5, 2026, moderate to heavy rain is potentially occurring in Kulon Progo, southern Gunungkidul, and southern Bantul with a wave height of 2.5 to 4.0 meters.

Meanwhile, on March 6, 2026, light to moderate rain is predicted to occur in northern Sleman, northern Kulon Progo, and northern Gunungkidul with a wave height of 2.5 to 4.0 meters.
