SINGAPORE: Hazy conditions are expected over parts of Singapore on Wednesday (Apr 11) due to a hotspot detected in Johor, Malaysia, said the National Environment Agency (NEA). 

"We have detected a hotspot with dense smoke plume in the southeastern part of Johor this afternoon. The smoke haze from the hotspot is being blown by the prevailing easterly winds towards Singapore,” NEA said in a Facebook post at about 5pm.

“For the next few hours, hazy conditions are expected over parts of Singapore, and members of the public may also detect a burning smell. The 24-hour PSI is forecast to be in the higher end of the moderate range."

The hazy conditions appear to have affected the eastern parts of Singapore, including Tampines. Some people reported a burning smell in the air.

NEA added that as of 5pm, the 24-hr PSI was 48-57, in the moderate range, while the 1-hr PM2.5 concentration readings were at 5-36µg/m3, in Band II (Elevated).

In an update at about 7.30pm, NEA said the situation has improved due to a shift in wind direction which is blowing the haze to the sea.

"The density of smoke haze from the hotspot detected in the southeastern part of Johor this afternoon has been reduced," said the agency. "The burning smell over eastern Singapore has lessened."

It added that the 1-hr PM2.5 concentration readings were 9-27µg/m3, in Band I (Normal), as of 7pm. 

"Slightly hazy conditions" can still be expected for the rest of Wednesday, said NEA. "We are monitoring the air quality closely, and will provide updates should there be any change in the situation."

In September last year, a strange burning smell was reported in many parts of Singapore, but that was eventually traced to a factory in Pasir Gudang in Johor.
