Review of Land Fires and Smoke Haze Situation for Second Fortnight of August 2019
1.1 During the second fortnight of August 2019, dry weather over Sumatra and Kalimantan was interspersed with occasional shower activities. In Sumatra, there were persistent clusters of hotspots detected in the central and southern parts of the island, particularly the provinces of Riau and Jambi. Moderate to dense smoke haze was observed to emanate from some of these hotspots.
1.2 In Kalimantan, significant smoke haze from persistent hotspot activities in Central Kalimantan resulted in widespread hazy conditions over the province. Hotspots with smoke haze were also detected in West, South and East Kalimantan. On a few days, some of the smoke haze from persistent hotspots in West Kalimantan was blown by the prevailing winds toward western Sarawak by the prevailing winds.
