BMKG issues extreme weather alert

Jakarta (ANTARA) – The Meteorological, Climatology, and Geophysics Agency (BMKG) has issued an alert for potential extreme weather in some regions of Indonesia from August 28 to September 3, 2022.

“It is indicated that there is a potential significance of atmospheric dynamics that could increase rainfall in several regions of Indonesia,” BMKG’s deputy for meteorology, Guswanto, said here on Saturday.

The Madden Julian Oscillation (MJO) phenomenon as well as an active Rossby wave have been forecast from August 28 to September 3, which could potentially increase the growth of rain clouds in several regions of Indonesia.

Based on these conditions, the BMKG has said there is potential for heavy rainfall accompanied by lightning and strong winds over the next week in Aceh, North Sumatra, West Sumatra, Riau, Riau Islands, Jambi, Bengkulu, South Sumatra, Bangka Belitung Islands, and Lampung.

Furthermore, West Kalimantan, Central Kalimantan, East Kalimantan, North Kalimantan, South Kalimantan, Southeast Sulawesi, West Sulawesi, Central Sulawesi, South Sulawesi, North Maluku, Maluku, West Papua, and Papua could also be potentially affected by these conditions.

Meanwhile, based on an impact-based forecast, Bangka Belitung Islands, Bengkulu, West Sumatra, West Kalimantan, Central Sulawesi, and Maluku have the potential for heavy rains in the “alert/need to be watched out for” category from August 27– 29.

Therefore, relevant parties need to make preparations, such as ensuring infrastructure capacity and preparing the water resource system, to anticipate increased precipitation, Guswanto said.

Some actions that can be taken include preventing littering and offhandedly felling trees and carrying out more massive greening programs, he added.

“(Also,) cutting fragile branches of trees, and strengthening pillars (of a house building) so that strong winds do not damage them,” he said.

The BMKG has also recommended intensifying education and literacy activities to increase awareness of local governments, communities, and related parties regarding preventive measures against hydrometeorological disasters.
