Latest Weather And Haze Situation
It was dry over the northern ASEAN region today, apart
from showers over parts of southeastern Mekong
sub-region and the northern Philippines. Clusters of
widespread hotspots were detected in Lao PDR, while
isolated to scattered hotspots were detected elsewhere in
the Mekong sub-region. Moderate to dense transboundary
haze was observed drifting eastwards from eastern
Myanmar into northern Thailand and northern Lao PDR,
from northern Thailand into northern Lao PDR, and from
northern Lao PDR into northern Viet Nam. Moderate
smoke plumes were observed to emanate from isolated
hotspots in eastern and western Thailand, western and
southern Cambodia, southern Lao PDR and central Viet
Nam. Many air quality stations in the northern and eastern
parts of the Mekong sub-region reported Unhealthy levels,
with a few stations reporting Very Unhealthy levels. A
partial satellite pass and cloud cover made it difficult to
determine the full extent of the hotspot and smoke haze
situation over the northern and southeastern parts of the
Mekong sub-region.
The southern ASEAN region was wet today, with the
overall hotspot and haze situation subdued. Few hotspots
were detected in 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 southern Philippines
where showers are forecast. The elevated hotspots and
transboundary haze situation is likely to continue in the
Mekong sub-region, especially in the northern areas. 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 continue
experiencing showers, which should keep the hotspot and
smoke haze situation subdued. 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.
