Monsoon weather that degrades visibility and runway conditions can simultaneously disrupt airport operations and ground access, compounding delays beyond the airfield itself.
Heavy rain and thunderstorms struck Delhi-NCR on Monday, diverting 14 flights from Indira Gandhi International Airport. Reduced visibility along with difficult wind and runway conditions prompted the diversions, and no fatalities linked to the weather disruption were reported.

The rain also triggered waterlogging in several parts of Delhi-NCR, slowing traffic considerably on major arterial roads. Flooded stretches combined with reduced visibility made it harder for passengers and airport staff to reach the airport on time.
Airport operators and airlines said they would assess conditions before restoring normal schedules, while civic agencies were expected to focus on clearing waterlogged roads. Authorities continued to monitor rainfall and traffic conditions as the weather system moved through the region.
This episode belongs to a familiar monsoon pattern in Delhi, where a single weather system strains both the road network and the airport at once, rather than affecting one in isolation. When visibility and runway conditions deteriorate together with waterlogged access roads, an airport's ability to recover a schedule depends as much on ground transport clearing as on the weather lifting.
For an airport handling diversions, restoring normal operations requires coordination between airside teams assessing runway and visibility conditions and civic agencies clearing flooded roads that staff and passengers need to reach the terminal. Delays in either compound the other.
What happens next depends on how quickly the weather system clears the region and how fast civic agencies drain the affected roads. Airlines and the airport operator have said they will reassess before resuming normal schedules, so the practical signal to watch is when diverted flights resume routing back to Delhi.
