As the mercury levels recorded a drop in Delhi and the National Capital Region (NCR), a thick layer of fog engulfed the national capital and adjoining areas leading to reduced visibility on Monday.
Visibility in the region dropped to less than 25m around 6 am and the vehicles were seen with their headlights on during the morning hours. People were seen around gas stations and on street corners huddled around large bonfires to beat the cold.
"Visibility recorded at 5:30 am today in Bhatinda-0 metres, Amritsar-25 and Ambala-25 metres each, Hissar-50 metres, Delhi (Safdarjung)-25 metres, Delhi (Palam)-50 metres; Uttar Pradesh: Agra-0 metre, Lucknow (Amausi)-0 metres, Varanasi (Babatpur)-25 metres, Bareilly-50 metres," according to the data from India Meteorological Department (IMD).
As per Satellite imagery and available visibility data from the IMD, the fog layer extended from Punjab and adjoining northwest Rajasthan to Bihar across Haryana, Chandigarh and Delhi and Uttar Pradesh.
The dense fog that engulfed the national capital caused delays in flight operations at the Indira Gandhi International Airport (IGIA). Just past midnight, the IGIA issued a statement saying: "Low visibility procedures are in progress at Delhi airport....Passengers are requested to contact the airline concerned for updated flight reactions."
As many as 29 trains were running late in the Northern Railway region alone on Monday, due to fog, including the Rajdhani Express trains. Delayed due to fog and cold, passengers were seen facing a lot of problems.
