In some areas around the Lodhi Road Observatory, the temperature plunged to below two degrees Celsius, recording a low of 1.7 degrees Celsius. The city was enveloped in dense fog, reducing visibility and affecting air traffic and vehicular movement in the streets.

Before this, the coldest day in December was December 11, 1996 when minimum temperature recorded at the observatory was 2.3 degrees Celsius.

Due to heavy fog on Saturday morning, four flights were diverted from Delhi airport, said an airport official. The official said that the flights were operating at the airport under CAT III B conditions, which means that the runway visual range (RVR) is between 50 metre and 175 metre.

According to railway officials, 24 trains were delayed due to poor visibility, ranging from 2-5 hours. Howrah New Delhi Poorva Express delayed by five hours.

The air quality turned severe again on Saturday, as falling temperatures, high humidity and low wind speed allowed accumulation of pollutants. The overall air quality index stood at 413 at 10 am. Cold wave and severe cold day has been forecast over Delhi-NCR on Saturday, said Kuldeep Srivastava, senior meteorologist at IMD.
