The city woke up to a layer of smog in the sky, while those who ventured out their homes complained of breathing discomfort, itching in eyes and overall uneasiness.
Experts suggest that high levels of PM 2.5 can trigger several respiratory issues, asthma attacks and even more difficulties for those already suffering from respiratory illnesses.

According to the Indian Institute of Tropical Meteorology (IITM), there has been a slight fall in maximum temperature over Delhi/ NCR, while wind speeds are also calm.
As per the weather agency’s air quality and weather bulletin for Delhi, the meteorological conditions are likely to be unfavourable for dispersion of pollutants.
Meanwhile, the concerned agencies have intensified anti- pollution and dust mitigating measures, as water sprinklers mounted on trucks were seen on roads, especially at the roads with more vehicles.
Mechanical sweeping of roads is also underway to mitigate dust which contributes to rise in pollution.
Actions under the Commission for Air Quality Management’s (CAQM) anti pollution Graded Response Action Plan’s (GRAP) stages I and II are in force across the national capital and adjoining areas to prevent further escalation of the situation.
