"Moderate to dense smoke haze was observed to emanate from clusters of hotspots detected in central and southern parts of Sumatra."

“While some isolated showers are forecast for Sumatra in the coming days, dry weather is expected to persist in parts of central and southern Sumatra, with the prevailing winds likely to continue blowing from the southeast or southwest.

“Under these conditions, the hotspot and smoke haze situation there could worsen, with an increased risk of transboundary smoke haze occurrence,” the alert read.

"This was corroborated by Datuk Wan Abdul Latiff Wan Jaffar, the director-general of Malaysia’s Department of Environment, who said that forest fires in Indonesia had caused transboundary haze to affect East Malaysia."

“Satellite imagery from the National Oceanic and Atmospheric Administration detected 52 hotspots in Sumatra, 264 hotspots in Kalimantan, and no hotspots detected within (Malaysia),” he was quoted sa saying by Free Malaysia Today.
