The India Meteorological Department (IMD) has predicted that fog will continue to envelope Delhi on Friday and the coming week. Friday morning's dense fog led to cancellation of and delays in a huge number of trains and flights. Road traffic also slowed down as traffic jams were wintessed in various places.
Over 100 flights have not been able to take off, while arrivals have begun.
All landings have been done using the CAT- III B system which allows landing even with 50-metre visibility, reports Press Trust of India.
Indira Gandhi International Airport in Delhi is the only airport in India equipped with the CAT-III system, which allows take offs for visibility as low as 125 metre and landing for 50 metre.
Low visibility has also affected vehicular movement on roads, as some areas in Delhi and the National Capital Region experienced traffic jams, reported NDTV.
Plying of trains have also been affected, with 130 of them running late and two cancelled, reported India Today.
The onset of the fog was sudden as the capital had been experiencing a warm winter. The IMD has said showers were expected in some parts of the city and the temperature is expected to be between 24.7 degree Celsius and 12 degree Celsius on Friday.
