It is predicted that the air quality would fluctuate between 'very poor' and 'poor' categories for some days.

New Delhi: The overall air quality in the national capital was recorded in the 'poor' category on Tuesday. According to the System of Air Quality and Weather Forecasting And Research (SAFAR), Air Quality Index (AQI) was recorded at 245 on Tuesday morning. The moderate wind speed is helping in the dispersion of pollutants and thus, preventing the air quality from worsening further.

High moisture in the air is increasing the air holding capacity. Cold wave conditions and moderate fog are likely to prevail in Delhi for a couple of days that might deteriorate the air quality slightly. SAFAR predicted that the air quality would fluctuate between 'very poor' and 'poor' categories for some days.
