The Ministry of Earth Science's air quality monitor, SAFAR, said dust from arid regions in the southwest has started affecting Delhi.
"Farm fires have begun in Amritsar, Punjab, and neighbouring border regions and are likely to influence the city's air quality," it said.
The farm fire count on Friday was around 40, according to the System of Air Quality and Weather Forecasting and Research (SAFAR).
"Deterioration in air quality index is expected on Saturday. Further deterioration -- from the higher end of the moderate category to poor category -- is expected on September 27 and September 28," it said.
Pawan Gupta, a senior scientist at Universities Space Research Association, NASA, said the forecast shows high PM2.5 levels across the Indo-Gangetic plains over the next 2-3 days.
"It appears a combination of smoke, dust and weather is playing a role," he said.
