Review of Land Fires and Smoke Haze Situation for Second Fortnight of May 2019

1.1 In the second half of May 2019, the increase of shower activities over the Mekong sub-region brought a further improvement to the hotspot and haze situation. There were still some isolated hotspot activities but these were gradually subsequently subdued by the rainy weather.

1.2 In the southern ASEAN region, occasional dry weather led to the emergence of isolated hotspots with smoke plumes in Riau, Sumatra, Peninsular Malaysia and West Kalimantan. However, these hotspot activities were short-lived and were subsequently subdued by shower activities.
