There were reports of traffic moving slowly in many areas of Delhi and the national capital region.
Dense fog blanketed many areas in and around Delhi this morning with poor visibility affecting over 100 flights and hitting road traffic in rush hour.
Departures and arrivals were on hold at the airport since 0415 hours as the runway visibility dropped to around 75 meters.
Flight operations resumed as visibility improved. But the halting of operations caused many delays and some cancellations and diversions.
On Twitter, passengers complained of delays up to three hours. "What could be more frustrating than sitting for three hours inside the aircraft and still waiting for takeoff ? Seriously. #DelhiFog," posted @YRDeshmukh.
Office goers also complained of traffic moving slowly in many areas of Delhi and the national capital region.
The first week of January this year has been the warmest for the city in at least 15 years, a senior Met department official has said. The minimum temperature for the ongoing period has been recorded four notches above normal.
While many complained of slow moving traffic due to fog, some Delhiites welcomed the winter chill.
"Hello delhi fog again. And thank you Universe for finally sending #dillikisardi hopefully our way. This 6c at night not cold enough," wrote @aparna_jain.
The MeT office has predicted overcast conditions for today along with the possibility of light rain and thundershowers in some parts of the capital.
The maximum and minimum temperatures are expected to hover around 24 degrees Celsius and 11 degrees Celsius respectively.
