Lastly, Semeru and Dukono in Indonesia remain on Alert Level II despite recent volcanic activity per PVMBG.
The ASMC forecasts wetter conditions over most parts of the ASEAN region and prevailing winds are forecast to continue blowing from the southeast or southwest. Based on a regional assessment of extremes, the ASMC sees a small increase in chance of heavy rainfall event in parts of the Borneo Island and northern Sulawesi. A small increase in chance of extended dry conditions in the parts of northern and central Philippines. There will also be a small increase in chance of extreme hot conditions in southern parts Java and Nusa Tenggara regions in Indonesia, the Philippines, and southern Myanmar.
