Mist and shallow fog hung low in the air in parts of the national capital a day after Diwali as visibility dropped significantly in the morning while the mercury settled at 20.5 degrees Celsius.
According to the MeT Department, the visibility reported at 8:30 am was 500 m and it improved as the day progressed.
"Mist and shallow fog were seen at many places in the morning. The smoke from the Diwali festivities last night added to the fall in the visibility level," the MeT said.
In Lutyens' Delhi, the Raisina Hill complex, which includes the iconic North Block and South Block buildings and the monumental Rashtrapati Bhavan, was wrapped in a misty cover even till 10:30 am.
