Delhi's air quality likely to enter 'severe' category on Diwali

Delhi recorded its air quality in the "very poor" category on Thursday with experts and government agencies saying it may enter the "severe" category on Diwali night. A change in the wind direction – from north westerly to north-north easterly – was the reason behind the dip in pollution levels as it reduced the contribution of stubble burning significantly, they said.

The city recorded a 24-hour average air quality index (AQI) of 314. It was 344 on Wednesday and 476 on Tuesday. Delhi witnessed six "severe" air days on the trot from November 4 to November 9, according to Central Pollution Control Board data. For more, watch the full video.
