HYDRO-METEO-CLIMATOLOGICAL:
For the past week, data from the ASEAN Specialised Meteorological Centre (ASMC) indicated medium to high 7-day average rainfall across the Maritime Continent, which includes Brunei Darussalam, Indonesia, and Malaysia. As of this reporting, there is no significant active tropical cyclone being monitored in the ASEAN region (JTWC).
GEOPHYSICAL:
Nine (9) significant earthquakes (M>5.0) were recorded by Indonesia’s Badan Meteorologi, Klimatologi, dan Geofisika (BMKG), the Philippine Institute of Volcanology and Seismology (PHIVOLCS), Myanmar’s Department of Meteorology and Hydrology (DMH), and Thai Meterological Department (TMD). Mount Ibu (alert level III), Dukono (alert level II), Lewotobi Laki-laki (alert level III), Ili Lewotolok (alert level II), Raung (alert levelII), Semeru (alert level II), and Marapi (alert level II) in Indonesia, and Kanlaon (alert level 3), Taal (alert level 1), and Mayon (alert level 1) volcanoes in the Philippines reported recent volcanic activity according to Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) and PHIVOLCS.
OUTLOOK:
According to the ASEAN Specialised Meteorological Centre (ASMC), for the coming week, wetter conditions are predicted over parts of the eastern Maritime Continent. For the regional assessment of extreme weather events, there is a small increase in chance of very heavy rainfall conditions to occurs over southern Thailand, parts of Sumatra, and Sulawesi. Furthermore, there is a moderate increase in chance of extreme heat conditions to occurs over northern Myanmar. La Niña conditions are transitioning to ENSO neutral conditions. ENSO neutral conditions have little influence on rainfall over the ASEAN region during the inter-monsoon period.
