The adverse weather conditions led to significant delays and diversions of flights since early morning.

Delhi airport issues travel advisory
Delhi Airport on Monday issued a passenger advisory after thick fog affected operations at Indira Gandhi International Airport in Delhi.
"While landings and take-offs continue at Delhi Airport, flights that are not CAT III compliant may get affected. Passengers are requested to contact the airline concerned for updated flight information. Any inconvenience caused is deeply regretted," reads the advisory issued by Delhi Airport.
The airport authorities initiated the anti-fog landing system, technically called the CAT-lll Instrument Landing System (ILS). The CAT III system helps with a precision approach and landing when the runway visibility level is low.
