Over a 24-hour period until 8:30 am, the city recorded a rainfall of 7.2 mm, while the humidity level remained at 96 percent.
The forecast from the weather office predicts a cloudy sky with the possibility of drizzle throughout the day.
An official from the India Meteorological Department said that the improved wind speed on Tuesday contributed to better dispersion of pollutants. (With inputs from PTI)
