Some 50 flights were affected, trains were canceled and vehicles butted into one another as fog covered much of north India Friday, national media reported.
According to The Times of India, visibility fell below 50 meters as the weatherman had forecast a further dip in temperature this weekend.
An official at the capital's Indira Gandhi International Airport was quoted as saying 30 domestic and 20 international flights were affected as the runway visibility range continued to remain well below 150 meters, the minimum required for flight operations.
"The visibility was poor due to fog and CAT III landing system was activated to help landing and take-off of flights, some of which were delayed, cancelled, diverted or rescheduled," the official said.
A Northern Railways spokesperson said 36 trains had been cancelled, 22 delayed and seven rescheduled.
"There was chaos on the roads, as morning commuters crawled with their hazard lights on but still could not avoid the occasional bump into the next car due to poor visibility," the daily reported.
Delhi recorded a minimum temperature of 8 degrees Celsius, a notch above the average for this time of the year, though the damp weather made it seem colder. The maximum temperature is expected to hover around 18 degrees Celsius.
