A layer of dense fog engulfed Delhi-NCR and several other parts of north India on Wednesday morning, significantly reducing the visibility. Cold wave conditions have gripped Uttar Pradesh, Haryana, Punjab, and several other regions across the country, as temperatures continue to drop significantly.

Severe poor visibility has significantly disrupted flight operations in the national capital and several other major cities, leaving many travellers stranded at railway stations.

Nearly 100 trains have been running late due to low visibility amid dense fog.

At least 118 flights were cancelled, 16 flights diverted and 130 services delayed at the Delhi airport on Tuesday as dense fog disrupted operations.

The Delhi Airport has issued an advisory, suggesting that operations were being conducted under CAT III protocols due to low visibility. This may lead to cancellations and delays.

Flyers have been urged to contact their airlines for updates before heading towards the airport.

“Due to prevailing dense fog conditions, flight operations are currently being conducted under CAT III protocols, which may result in delays or cancellations. Our ground teams are on-site and actively
