Delhi Chokes Under ‘Severe’ Air As AQI Nears 450; Dense Fog Triggers Red Alert In UP
The India Meteorological Department (IMD) issued a Red Alert for Uttar Pradesh, while warnings were extended to 15 other states due to persistent fog conditions.
Visuals from the Akshardham area on Thursday showed Delhi’s air quality firmly in the poor category, with the Air Quality Index (AQI) hovering around 450. Large parts of the national capital continued to reel under toxic air conditions, compounding weather-related disruptions.
Dense Fog Engulfs North India
A thick blanket of fog settled over large swathes of northern India on Thursday morning, severely affecting daily life. Road traffic slowed to a crawl in several areas as visibility dropped to near-zero levels. Train services and flight operations were also impacted across the region.
The India Meteorological Department (IMD) issued a Red Alert for Uttar Pradesh, while warnings were extended to 15 other states due to persistent fog conditions.

The intensity of the fog was felt a day earlier as well, with a cricket match in Lucknow abandoned on Wednesday due to extremely low visibility.
Delhi’s Double Challenge: Smog And Severe Pollution
In Delhi, hazardous air quality added to the weather emergency. AQI levels in most parts of the city remained close to 400 (Severe), while visibility dropped below 100 metres during peak morning hours, leading to heavy traffic congestion.
To curb further deterioration, authorities enforced GRAP-4 (Graded Response Action Plan) measures across the capital.

Cold Wave Warning: Western Madhya Pradesh and Uttarakhand
Thunderstorms and Lightning: Tamil Nadu, Kerala, and the Andaman & Nicobar Islands
Advisory For Commuters
