77
Posted: 19 October 2010 1924 hrs
SINGAPORE : The haze is back in Singapore, as the
southwesterly winds blow in the smoke from the fires in
Sumatra.
The National Environment Agency (NEA) said the 3-hour PSI reading
on Tuesday climbed from 78 at 6pm to 84 at 8pm before dropping to
77 at 9pm. Though the readings are still in the moderate range, the
condition has worsened from the 24-hour reading of 56 at 4pm.
The 24-hour PSI is a measure of the air quality over a period of 24
hours. It is updated at 4pm daily. The 3-hour PSI reading is a
measure of the air quality over a period three hours. It is updated
on the hour.
A PSI reading of above 100 is considered unhealthy.
The NEA said the latest satellite pass detected 202 hotspots in
Sumatra, mainly in the provinces of South Sumatra, Jambi and
Riau.
The winds are expected to remain southwesterly to westerly from the
evening to Wednesday, and showers with thunder are expected in the
late morning and afternoon on Wednesday.
NEA said the showers should help to mitigate some of the smoke
haze, but there is still a possibility that some slight haziness
may remain over the next few days.
The agency is monitoring the smoke haze situation closely and will
provide updates should the air quality deteriorate.
Members of the public may also call the NEA Call Centre at
1800-CALL NEA (1800-2255-632) or access www.nea.gov.sg for any
feedback or update on the situation.
