Latest Weather And Haze Situation
It was dry over the northern ASEAN region overnight.
Based on the overnight pass, scattered to widespread
hotspots were detected in the Mekong sub-region.
Moderate to dense smoke haze was observed to envelop
over large parts of Myanmar, northern Thailand, northern
Lao PDR and northern Viet Nam. Slight to moderate
smoke haze was also observed over the eastern and
western parts of Thailand, the northern and western parts
of Cambodia, the southern parts of Lao PDR and the
central parts of Viet Nam. Many air quality stations in the
northern and eastern parts of the Mekong sub-region
reported Unhealthy levels, with a few stations in the
northern parts reporting Very Unhealthy levels. A few
ground observations in the northern parts of the
sub-region reported low visibility. The full extent of the
hotspot and smoke haze situation over the southeastern
parts of the Mekong sub-region cannot be determined due
to cloud cover.
The southern ASEAN region was generally wet overnight.
Few hotspots were detected in Peninsular Malaysia,
Kalimantan, Sabah and Sarawak, but no significant
smoke plumes were observed from satellite imagery.

Weather And Haze Outlook
Dry weather is expected to persist over the northern
ASEAN region, except over the Philippines where
showers are forecast. The elevated hotspots and
transboundary haze situation is likely to continue in the
Mekong sub-region. The prevailing winds over the
Mekong sub-region are expected to blow from the
southwest to west, whereas the prevailing winds over the
Philippines are forecast to blow from the east to
southeast.
The southern ASEAN region is likely to experience
showers, which should keep the hotspot and smoke haze
situation subdued. However, few to isolated hotspots with
localized smoke plumes may still occur in drier areas. The
prevailing winds over areas south of the Equator are
expected to blow mainly from the southeast, while light
and variable winds are forecast over areas near the
Equator.
