Generally dry weather prevailed over Sumatra today, but there were afternoon thundery showers over parts of Sarawak and Kalimantan. Hotspots with smoke haze continued to be detected in the provinces of Riau, Jambi and South Sumatra. In particular, moderate to dense smoke haze was detected from hotspots in Riau and South Sumatra. Blown by the prevailing winds, smoke haze in Riau has spread over the Strait of Malacca. In Kalimantan, hotspots with smoke haze continued to be detected in West Kalimantan and Central Kalimantan despite cloud conditions due to the thundery showers. For the next few days, the weather is expected to remain generally dry over Sumatra and some shower activities are forecast over Kalimantan. With hotspot activities and hazy conditions persisting in central Sumatra, smoke haze may be blown by the prevailing winds toward the west coast of Peninsular Malaysia.
