The ASEAN Specialised Meteorological Centre (ASMC) reported that the Southwest Monsoon is in effect in the ASEAN region since late May 2020, where more rain falls over the northern ASEAN region compared to the southern ASEAN region. The presence of the monsoon rain band over the northern ASEAN region is bringing increased shower activities.
Nine (9) significant earthquakes (M≥5.0) were recorded in the region from 08-14 June by Indonesia’s Badan Meteorologi, Klimatologi dan Geofisika (BMKG).
Meanwhile, three (3) volcanoes in Indonesia (Karangetang,
Agung, Sinabung) under Alert Level III - Siaga (PVMBG) are under close monitoring. Lastly, despite recent volcanic activities shown by Sangeang Api, Semeru, and Dukono in Indonesia, they remain on Alert Level II – Waspada.
The ASMC forecasts that increased shower activities are to be expected over many parts of the ASEAN region. Based on a regional assessment of extremes, the ASMC sees a moderate increase in chance of a heavy rainfall event and extended dry conditions, very likely extreme hot conditions and low increase in chance of extreme cold conditions in parts of the region in the coming week.
