For the past week, data from the ASEAN Specialised Meteorological Centre (ASMC) showed medium to high 7-day average rainfall spreading across Sumatra, northern Kalimantan, south Sulawesi, Maluku, and Papua in Indonesia; Southern Myanmar; Luzon and Visayas in the Philippines; and southern parts of Viet Nam. As of reporting, TC Talilm equivalent to Category 1 hurricane (on the Saffir-Simpson Scale), is located in NW Pacific Ocean with maximum sustained winds of 130 km/h. TC Talim is headed west-northwest at about 20 km/h and is expected to made its initial landfall over northern parts of Viet Nam on the evening/afternoon of 18 July 2023 (NCHMF, JTWC). Meanwhile, INVEST 98W has persisted approximately 1,100 km east of Mindanao. Forecast models are in agreement that INVEST 98W will steadily develop as it remains quasi-stationary before propagating northward in around 2 days. (JTWC).
Three (3) significant earthquakes (M>5.0) were recorded by Indonesia’s Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) and the Philippine Institute of Volcanology and Seismology (PHIVOLCS). Mount Semeru (alert level III), Ili Lewotolok (alert level II), and Karangetang (alert level III) in Indonesia, and Mayon Volcano (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.
According to the ASEAN Specialised Meteorological Centre (ASMC), for the coming week, wetter conditions are predicted over much of Mainland Southeast Asia and the Philippines; drier conditions are predicted over parts of the western and central equatorial region; warmer than usual temperature is expected over much of the southern ASEAN region. For the regional assessment of extremes, there is a moderate increase in chance for a very heavy rainfall event to occur in Northern Philippines parts of Mainland Southeast Asia; and very likely in the parts of southeastern Maritime Continent, and moderate increase in chance in the parts of Maritime Continent and Myanmar for extreme hot conditions. El Niño conditions are likely to be established during July – August 2023. During July and August, El Niño events tend to bring drier conditions to much of the southern ASEAN region.
