HYDRO-METEO-CLIMATOLOGICAL:
For the past week, data from the ASEAN Specialised Meteorological Centre (ASMC) showed moderate to high 7-day average rainfall spreading across Brunei Darussalam; Lao PDR; Cambodia; northern Sumatra, northern Kalimantan, and Papua in Indonesia; Peninsular, Sabah, and Sarawak Malaysia; Central and Coastal parts of Myanmar; Luzon in the Philippine; and Central parts of Viet Nam. As of reporting, Tropical Disturbance INVEST 92W was estimated, based on all available data, at 435 km South-Southeast of Kadena AB, Okinawa. Global forecast models show that INVEST 92W will drift slowly southward over the next 2 days with no significant development (JTWC).
GEOPHYSICAL:
Seven (7) significant earthquakes (M>5.0) were recorded by Indonesia’s BMKG and the Philippine Institute of Volcanology and Seismology (PHIVOLCS). Mount Ibu (alert level II) in Indonesia, and Mayon (alert level 3), Taal (alert level 1), and Kanlaon (alert level 1) in the Philippines reported recent volcanic activity according to Indonesia’s Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) and PHIVOLCS.
OUTLOOK:
According to the ASEAN Specialised Meteorological Centre (ASMC), for the coming week, drier conditions are predicted over much of the southern ASEAN region, with the highest likelihood over the southwestern part of the region; warmer conditions are expected over most of the southern ASEAN region. For the regional assessment of extremes, there is a small increase in chance for a very heavy rainfall event to occur in the parts of southern Myanmar and northeast Thailand; a small increase in chance for extreme hot conditions to occur in Western Maritime Continent and parts of Java. El Niño conditions are predicted to strengthen over the next few months. At the seasonal timescale during September to November, El Niño events bring drier conditions to much of the ASEAN region.
