End of Dry Season for the Southern ASEAN Region

There have been more shower activities over the southern ASEAN region in the past few weeks. Based on surveillance by the NOAA-20 satellite, a total of 0 and 11 hotspots in Sumatra were detected on 28 and 29 Oct 2020 respectively, while 1 hotspot was detected in Kalimantan on each of these two days.

In the coming weeks, the prevailing winds are forecast to become light and blow from the northeast or northwest in the southern ASEAN region. Increased shower activities are also expected over most parts of the region. This will help to subdue hotspot activities and decrease the likelihood of transboundary haze. However, there could still be isolated hotspots with localised smoke haze during brief periods of drier weather.

End of Dry Season for the Mekong Sub-region

Over the past week, there have been increased showers over the Mekong sub-region. Based on surveillance by the NOAA-20 satellite, the total hotspot count in the Mekong sub-region remained low, with 147 and 69 hotspots detected on 16 May 2020 and 17 May 2020 respectively.

With rainy weather forecast over the Mekong sub-region in the coming days, hotspot activities are expected to be generally subdued.

End of Dry Season for the southern ASEAN region

The gradual transition to Northeast Monsoon conditions over the past few weeks has brought an increase in showers over the southern ASEAN region. Based on surveillance by the NOAA-20 satellite, a total of 21 and 8 hotspots were detected in Sumatra, while 5 and 6 hotspots were detected in Kalimantan, on 18 and 19 Nov
2019 respectively.

With Northeast Monsoon conditions expected to prevail, rainy weather can be expected over most parts of the region. However, occasional dry conditions can be expected in the southern parts of Sumatra and Kalimantan. Hotspots with smoke haze can still be expected there. With the prevailing winds forecast to blow from the north or northeast, transboundary haze occurrences are unlikely.

End of Dry Season for the Northern ASEAN Region

There have been scattered showers over the northern ASEAN region in the past week. Based on surveillance by the NOAA-19 satellite, the total hotspot count in the Mekong sub-region remained low, with 20 and 47 hotspots detected on 14th May 2019 and 15th May 2019 respectively.

With rainy conditions forecast to persist over the northern ASEAN region, hotspot activities are expected to remain generally subdued.

Downgrade of Alert Level from 1 to 0 for the southern ASEAN region

With the onset of inter-monsoon conditions in mid-October 2018, the southern ASEAN region, including Sumatra and Kalimantan has been experiencing an increase in shower activities.

The number of hotspots detected in Sumatra and Kalimantan has remained low in recent days. Based on surveillance by the NOAA-19 satellite, no hotspots were detected in Sumatra, and 6 and 0 hotspots were detected in Kalimantan on 17 and 18 Oct 2018 respectively. No significant smoke haze was observed in the region.

More rainy weather can be expected over the region with a gradual transition to the Northeast Monsoon season in the coming weeks. Hotspot activities in the southern ASEAN region are expected to remain generally subdued. While isolated hotspots may still emerge during brief periods of dry weather, these hotspots are likely to be localised and short-lived.

Downgrading of Alert Level 1 to Alert Level 0 for the northern ASEAN region

The northern ASEAN region has been experiencing an increase in shower activities in the past several days.

Based on surveillance by the NOAA-19 satellite, there has been a significant decrease in the number of hotspots detected in the Mekong sub-region including Cambodia, Myanmar, Lao PDR, Thailand and Vietnam over the past week. A total of 52 and 28 hotspots were detected on 14 and 15 May 2018 respectively in the Mekong sub-region.

Wet weather conditions are expected over the northern ASEAN region for the rest of the month, with more shower activities forecast when the Southwest Monsoon onsets in June 2018. Hotspot activities are likely to remain subdued, although isolated hotspots may still be detected occasionally.

End of dry season for the southern ASEAN region

With the onset of inter-monsoon conditions in mid-October 2017, the southern ASEAN region has been experiencing an increase in shower activities. Bases on surveillance by the NOAA-19 satellite, 8 and 2 hotspots were detected in Sumatra, while 0 and 6 hotspots were detected in Kalimantan, on 25 and 26 October 2017 respectively.

Increased in rainfall can be expected over the region with gradual transition to the Northeast Monsoon season in the coming weeks. This will help to further subdue the hotspot activities in Sumatra and Kalimantan.

End of Dry Season for the northern ASEAN region

The northern ASEAN region has been experiencing an increase in shower activities since late April 2017. Over the past several days, showers in the Mekong sub-region have helped to subdue hotspot activties there. Based on surveillance by the NOAA-19 satellite, a total of 24 and 11 hotspots were detected in the Mekong sub-region including Cambodia, Myanmar, Lao PDR, Thailand and Vietnam on 7 and 8 May 2017 respectively.

In the coming weeks, more shower activites are expected over the northern ASEAN region with the transition to the Southwest Monsoon season in June 2017. Hotspot activities in the Mekong sub-region are expected to be generally subdued.

End of dry season for the southern ASEAN region

Over the past weeks, shower activities have continued to subdue the hotspot and haze situation in the region, including the fire-prone provinces of Sumatra and Kalimantan. Based on surveillance by the NOAA-19 satellite, 0 and 0 hotspots were detected in Sumatra, while 4 and 2 hotspots were detected in Kalimantan, on 26 and 27 October 2016 respectively.

In the coming weeks, increased rainfall can be expected over the region with the gradual transition to the Northeast Monsoon season. This will help to further subdue the hotspot activities in Sumatra and Kalimantan.

End of dry season for the northern ASEAN region

The northern ASEAN region has been experiencing an increase in shower activities with the onset of the Inter-monsoon season in late April 2016. Over the past few days, the showers in the Mekong sub-region have helped to subdue hotspot activities there. Based on surveillance by the NOAA-19 satellite, a total of 22 and 37 hotspots were detected in the Mekong sub-region including Cambodia, Myanmar, Lao PDR, Thailand and Vietnam on 18 and 19 May 2016 respectively.

In the coming weeks, more showers activities are expected over the region with the transition to the Southwest Monsoon season around mid-June 2016. Hotspot activities in the Mekong sub-region are expected to be generally subdued.
