According to the ASEAN Specialised Meteorological Centre (ASMC), for the coming week, wetter conditions are expected over parts of the eastern Maritime Continent. Drier conditions are expected over much of central and eastern Mainland Southeast Asia. Cooler conditions are expected over much of central and southeastern Mainland Southeast Asia. For the regional assessment of extremes, there is a small increase in chance to occur in Peninsular Malaysia, and a moderate chance in Sulawesi, Nusa Tenggara, and Maluku Islands for a very heavy rainfall event; a moderate increase in chance for extreme hot conditions to occur in Much of the Philippines, southeastern Maritime Continent. La Niña conditions have been present. At the seasonal timescale, La Niña events tend to bring wetter conditions to much of the ASEAN region. A negative Indian Ocean Dipole (IOD) is also present. Negative IOD events tend to bring wetter conditions to much of the southern ASEAN region.
