Incessant heavy rains today led to water-logging at IGI airport in New Delhi, causing inconvenience to passengers who waded through knee deep water while the baggage handling system was left crippled.            

The monsoon arrived in Delhi today a fortnight ahead of schedule, with national capital recording around 36.6 mm rainfall. But the airport witnessed an "unprecedented" rainfall of 117.8 mm in four and half hours, between 1 PM and 5.30 PM.            

The airport experienced 62.8 mm of rains between 1 pm and 2.30 pm and 55 mm between 2.30 PM and 5.30 pm. The amount of rain water, combined with poor drainage in the surrounding area and topography of airport led to back flow of water towards the Terminal 3 of the airport.
