New Delhi: As the country is celebrating Diwali with fire crackers lightening the night sky, the air quality in national capital is set to further deteriorate and reach the “upper end” of the ‘very poor’ category by midnight and shoot up rapidly by Friday morning, as per morning bulletin issued by the Air Quality Early Warning System for Delhi.

On November 5, the air quality will remain in the ‘very poor’ category, but could deteriorate to ‘severe’ if there are firecracker emissions on Diwali day, the forecast said.

The AQI has remained in the lower end of the ‘very poor’ category for the past two days. AQI from 301 to 400 is considered ‘very poor.’

The wind direction on Thursday could be from variable directions, while the direction on Friday is likely to be from the northwest of Delhi, and this could increase the contribution of crop residue burning to PM2.5 levels in the city. Low wind speed has been making the dispersion of pollutants difficult so far, but strong winds are predicted on November 6.

Meanwhile, the minimum temperature on Thursday is likely to stand at 15 degrees Celsius, with the maximum at 29 degrees Celsius, according to the India Meteorological Department (IMD). Clear skies are on the forecast for the day. The minimum temperature recorded over the past 24 hours was 15 degrees Celsius, while the maximum was 29.9 degree Celsius, a degree below the normal.
