Over the next few days, shower activities are expected to prevail over most of the ASEAN region, apart from parts of Cambodia, Viet Nam, Java and the Lesser Sunda Islands where relatively drier conditions are likely. Though localized hotspots and smoke plume may occur in drier areas, the overall hotspot and smoke haze situation is likely to remain subdued. The prevailing winds north of the Equator are forecast to blow from the southeast or southwest, while the prevailing winds south of the Equator are forecast to blow mainly from the southeast.
