New Delhi: The national capital continues to reel under intense cold with a thick blanket of fog affecting the road, rail and air traffic on Thursday.

According to ANI, Delhi probably experienced its coldest day of this season today as the minimum temperature recorded in the Palam this morning remained at 7 degree Celsius.

Delhi continues to be shrouded in dense fog for the fourth consecutive day, which has severely affected services at both the Indira Gandhi International (IGI) Airport and the railway stations.

Nearly 49 trains were delayed, and at least 12 cancelled due to dense fog and zero visibility.

Hundreds of passengers at several railway stations in north India have been left stranded after multiple trains have been cancelled, delayed, and rescheduled due to dense fog.

Low visibility due to the fog has disrupted flight operations at the Indira Gandhi International airport.

At least 20 flights were delayed, according to ANI.

Heavy fog on January 1 had forced the airport authorities to suspend all flights for several hours before visibility returned.

Delhi airport has advanced technology for low-visibility landings, called CAT IIIB. 

As a result, landings can take place with a visibility of 50 metres.

However, for take-offs, a minimum visibility of 125 metres is required.

Misty conditions on Wednesday evening also brought traffic to a crawl in Gurgaon.

The air quality in the national capital has been keeping under 'very poor' category as the fog has not been allowing the particulate matter to disperse.

The weather condition is likely to remain the same for the next few days, according to the India Meteorological Department.
