According to the ASEAN Specialised Meteorological Centre (ASMC), for the coming week, warmer conditions are predicted over the coastal regions of eastern Mainland Southeast Asia; cooler conditions are predicted for northwestern Mainland Southeast Asia. For the regional assessment of extremes, there is a low chance for extreme hot conditions to occur in southeastern mainland Southeast Asia, northern Philippines, and the Malay Peninsula; and small increase in chance for extreme cold conditions to occur in Myanmar. 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.
