Dense fog blanketed the national capital again on Wednesday, dropping visibility to nearly zero, disrupting over 100 flights and delaying at least 30 trains, while many were rescheduled or even cancelled.
In the city, visibility dropped to near zero at 5.30 am and continued to remain below 50 metres, said an India Meteorological Department (IMD) official. It affected road traffic as well, with motorists forced to drive slow.
Visibility at the runways of Indira Gandhi International Airport was below 100 metres at 9.30 am, affecting over 100 domestic and international flights.
"The low visibility landing procedure was activated due to poor visibility. Several domestic and international flights have been diverted and rescheduled due to the fog," an airport official said.
The fog wreaked havoc on rail services as well with over 30 trains running late.
"As many as 11 trains have been rescheduled and seven cancelled due to the fog," said a northern railways official.
The minimum temperature on Wednesday settled at 9.8 degrees Celsius, two notches above average.
The met officials attributed the fog to moisture in the atmosphere and have forecast the maximum temperature to settle around 22 degrees Celsius.
