JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) predicts that most of Indonesia will experience light rain on Thursday, May 21.
BMKG weather practitioner Lintang Alya N said that the areas with the potential for light rain include the areas of Sumatra, Java, as well as Pontianak, Palangka Raya, Samarinda, and Tanjung Selor.
He also reminded the public to be aware of the potential for lightning in Banjarmasin.
Meanwhile, he said, for eastern Indonesia, it is necessary to be aware of the potential for moderate rain in Mamuju and the potential for light rain in Mataram, Kupang, Kendari, Palu, Manado, Ternate, Ambon, Sorong, Manokwari, Nabire, Jayapura, and Jayawijaya.
"In addition, there is the potential for cloudy to cloudy weather in Denpasar, Makassar, Gorontalo, and Merauke," said Alya, quoted by Antara, Thursday morning.
He explained that the cyclonic circulation was observed to be formed in the West Indian Ocean Lampung and in the North Pacific Ocean Papua.
The system formed convergence and confluence areas in the West Indian Ocean Lampung and in the northern waters of Papua, as well as around the cyclonic circulation.
"Other convergence areas are also observed to be formed on the northern coast of Aceh, the Malacca Strait, from West Sumatra to the western waters of Bengkulu, from Central Kalimantan to West Kalimantan," said Lintang.
He added that this phenomenon is also formed from South Kalimantan to Central Kalimantan, Southeast Sulawesi to Central Sulawesi, and from Papua Mountains to West Papua.
Other areas of confluence were also observed in the South China Sea and the West Indian Ocean from Lampung to South Banten.
He said that this condition was able to increase the potential for rain cloud growth around the cyclonic circulation and along the convergence and confluence areas.
The combination of atmospheric dynamics, he said, causes the potential for weather to be quite significant in several regions of Indonesia. Preparedness for the potential for heavy to very heavy rain in the North Sumatra, Central Java, and East Java regions needs to be increased.
