GEOPHYSICAL:
Eight (8) significant earthquakes (M?5.0) were recorded in the region by Indonesia’s Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) and Philippine Institute of Volcanology and Seismology (PHIVOLCS). Mount Semeru (alert level III), Anak Krakatau (alert level III), Merapi (alert level III), and Ili Lewotolok (alert level III) in Indonesia, and Taal (alert level 1), Kanlaon (alert level 1), Bulusan (alert level 1), and Mayon Volcano (alert level 2) in the Philippines reported recent volcanic activity according to the Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) and PHIVOLCS.
OUTLOOK:
According to the ASEAN Specialised Meteorological Centre (ASMC), wetter conditions are expected over parts of the central Maritime Continent and Malay Peninsula; drier conditions over parts of western and central Mainland Southeast Asia; cooler conditions are expected over parts of southern Maritime Continent and central and eastern Mainland Southeast Asia; and warmer conditions are expected over parts of Myanmar. For the regional assessment of extremes, there is a small increase in chance for a very heavy rainfall event to occur in central parts of Mainland Southeast Asia, and a moderate chance in the Maritime Continent region; a moderate increase in chance for extreme hot conditions to occur in Philippines, and southern and eastern parts of Indonesia. La Niña conditions have been present which seasonally tend to bring wetter conditions to much of the Maritime Continent. A negative Indian Ocean Dipole (IOD) is also present which tend to bring wetter conditions to much of the ASEAN region.
