The residents of Delhi on Tuesday once again woke to dense fog and bone-chilling cold that also hit flight and rail operations, leaving thousands of passengers waiting for hours at the airport and railway stations.

According to the India Meteorological Department (IMD), the city’s Palam(VIDP) and Safdarjung Airports recorded visibilities within 500 metres in the morning, while around 30 flights departing from Delhi’s Indira Gandhi International Airport (IGIA) were delayed, and 17 flights were cancelled due to low visibility amid dense fog, news agency ANI reported citing the airport officials.

The weather agency said a fog patch can be seen over the northern and north-eastern states with low visibility areas recorded in the airports situated in these states.

“Layer of fog is seen from Punjab to northeast India across Haryana, North MP, UP, Bihar and West Bengal at 0530 hrs IST. The patches of fog are also seen along the east coast of India as shown in the attached Satellite Imagery,” the IMD said in a post on X.
