The Agency for Meteorology, Climatology and Geophysics (BMKG) has urged the public to prepare for Tropical Cyclone Herman, which can bring extreme weather conditions in the form of heavy rain with strong winds in Yogyakarta.
“Tropical Cyclone Herman increases the air supply in the Java region, so convective cloud activities also increase. This causes quite extreme weather conditions in Java and Yogyakarta,” the head of Yogyakarta BMKG Meteorological Station Warjono said on Friday.
He said the tropical cyclone is forecast to be active until April 4, 2023.
He explained that the cyclone’s position was detected on Wednesday (March 29) in the Indian Ocean, south of Central Java and Yogyakarta, and it is forecast to move southeast at a speed of five knots.
Then Tropical Cyclone Herman is projected to move toward the center of Indonesian waters and back to the west.
“It will move to the south of Central Java and Yogyakarta. The peak will be on the east side today, at 12 pm local time, and it will return to the west,” he remarked.
He added that the movement of the cyclone would cause extreme weather similar to what happened recently in Yogyakarta.
“It could be a heavy rain accompanied by wind and even hail,” he said.
Warjono said convective cloud growth that can cause extreme weather would usually start to form west of Mount Merapi, Salaman, Magelang or Turi district, Sleman.
Towering and dark convective clouds may move towards the city of Yogyakarta via Kulon Progo or Sleman and then continue towards Bantul and Gunung Kidul.
Although the showers would be short, the regions where the clouds pass will be affected by destructive winds, he said.
Also, whirlwinds can occur in the Bantul region, which is flat land.
“The pattern (cloud movement) occurs locally in Yogyakarta. We have to be careful with this, so we will be better prepared to face it when there are signs of extreme weather in the region”, he remarked.
