“For around four hours -- between 4.30am and 8.30am -- the visibility was zero at Palam. It was only around 9am that it improved to 50 metres here. When visibility is zero, flight operations have to be suspended,” said Kuldeep Srivastava, head of IMD’s regional weather forecasting centre.

At Safdarjung Observatory --- representative of Delhi’s weather, moderate fog was observed with the visibility reduced to 300 metres at 8.30am.

“The season of fog has started. Easterly winds that were blowing over Delhi till Sunday noon brought moisture. High moisture content combined with low wind speed resulted in heavy fog. We are expecting moderate fog at Safdarjung over the coming week,” said Srivastava.

He added that the visibility may improve slightly over the next few days because of high wind speed, however, shallow to moderate fog is here to stay.
