According to the ASEAN Specialised Meteorological Centre (ASMC), for the coming week, wetter conditions are expected over much of the southern ASEAN region. Cooler than usual temperatures are expected over much of the western and central equatorial region. For the regional assessment of extremes, there is a small increase in chance for a very heavy rainfall event to occur in parts of southern Maritime Continent, in particular southern Borneo, eastern Java, and southern Sulawesi; and moderate increase in chance for extreme hot conditions to occur in the southeastern Maritime Continent. La Niña conditions are still present in the Pacific. At the seasonal timescale, La Niña events tend to bring wetter conditions to much of the ASEAN region. Negative Indian Ocean Dipole is likely to develop by July. Negative IOD tend to bring wetter conditions to much of the ASEAN region.
