SINGAPORE - It is possible that the haze could recur in the coming days, the National Environment Agency (NEA) said on Tuesday (Sept 27).

According to NEA, "Singapore could experience slightly hazy conditions" if hot spot activity increases in Sumatra, where dry weather conditions are expected.

The wind is expected to blow from the west this week. Thirteen hot spots were detected in Sumatra on Tuesday, with no visible smoke plumes or haze observed.

The Wednesday forecast predicts that the 24-hour PSI will stay in the moderate range and the 1-hour PM2.5 concentration in the normal band, unchanged from Tuesday.
