Several social media users took to X to report smelling smoke and experiencing hazy conditions across different parts of the city, with some even flagging reduced visibility as celebrations gathered pace.
According to the Air Quality Early Warning System (EWS) for Delhi, the air quality is likely to remain in the 'severe' category from November 9 for the subsequent few days.
Weather and air quality experts have attributed the anticipated deterioration to firecrackers, vehicular emissions and the ongoing peak period of stubble burning in neighbouring states, with unfavourable meteorological conditions further aggravating the situation.

PM2.5 was the predominant pollutant in the national capital on Sunday, with emissions from firecrackers adding to the levels of particulate matter.
According to the Decision Support System (DSS) for Delhi, the transport sector was set to be the largest contributor to the city's pollution on Sunday, accounting for 19 per cent.
Stubble burning was set to contribute 3.5 per cent on Sunday, with forecasts suggesting the contribution might remain around 2.99 per cent on Monday.
