Dense fog enveloped many parts of the national capital region including Delhi, affecting vehicular traffic and causing delays and diversion of many flights at IGI Airport. 

Fog started to descend upon the city around midnight and it engulfed the entire city by Tuesday morning, reducing the general visibility to almost zero.

Road traffic bore the brunt of poor visibility as traffic moved slowly in most part of the city.

Operations at IGI airport in New Delhi also came to a standstill on Tuesday, affecting over 40 domestic and international flights.

The flights, scheduled around 5 am, were disrupted as visibility on all the three runways were below 50 metres, airport officials said. Around 40 domestic and international flights, arriving and departing from Delhi, were delayed by up to two to three hours. Some arriving flights were diverted while two were cancelled.

The fog started to become dense around 5 am and the visibility went below 50 metres, the minimum required for landing under poor visibility conditions using the CAT-III B instrument landing system (ILS).

The minimum visibility for an aircraft to take off under low visibility conditions is between 125 to 150 metres, depending on the size of the plane. On Monday, schedules of around 140 flights were badly affected after Delhi witnessed the winter's first fog. Nine flights were diverted while eight were cancelled.

Train services were also affected due to fog in the region. 17 trains have been delayed.
