4 flights cancelled, 17 diverted as dense fog envelops Delhi

Skies are expected to clear up during the day and shallow to dense fog is likely to engulf the city on Monday

Over 90 flights were affected on Sunday morning as a thick blanket of fog enveloped the national capital, bringing down the visibility to 50 metres.

While 54 domestic flights were delayed and 17 diverted to other airports, eleven international flights were delayed and 8 were diverted due to the dense fog, according to flight information available on the airport's website.

So far there have been 4 cancellations, including three domestic and one international flight, according to the information.

RK Jenamani, Director, IMD, Delhi area and IGI airport said, "Runway visibility since 5.30 am has been between 50-75 metres. This is so far the worst fog we have experienced this year."

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.

Humidity in Delhi was recorded at 97 per cent while visibility stood at 400 metres, said a senior official from the MeT department.

Skies are expected to clear up during the day and shallow to dense fog is likely to engulf the city tomorrow morning, he added.

The maximum temperature is likely to hover around 22 degrees Celsius, he said.

On Saturday, the maximum and minimum temperatures were recorded at 22.6 and 7.2 degrees Celsius respectively.
