New Delhi, Jan 3 (IANS) The air quality in the national capital and adjoining areas continued to be in the ‘severe’ category on the third day of 2019 and experts say it is expected to worsen.

“The Air Quality Index (AQI) is expected to go up further within the ‘severe’ range until Friday afternoon,” the System of Air Quality and Weather Forecasting And Research (SAFAR) said on Thursday.

The ‘severe’ situation is likely to deteriorate further as the India Meteorological Department has forecast light to very light rains from January 5 to 7.

“The winter pre-shower conditions which introduces a huge amount of moisture with dense fog is responsible for a peak in the current scenario. Only sufficient rain can bring relief as a little shower only aggravates the situation,” SAFAR said.
