– Citywide Effects: Severe waterlogging, traffic jams, and power outages across Delhi and the National Capital Region (NCR)
– Vehicle Damage: Dozens of vehicles stranded or submerged in the main underpass leading to the airport

The storm’s effects were not limited to the airport. Across Delhi, heavy rain and strong winds caused waterlogging, traffic snarls, and power cuts. The main underpass to the airport was flooded for hours, leaving many vehicles stranded and damaged.

Official Response: Safety First, Operations Restored

Delhi International Airport Limited (DIAL), which manages the airport, quickly issued statements to calm public fears. According to DIAL, the collapse involved only a section of the external tensile fabric at the T1 Arrival forecourt. The structure adjusted under pressure, which actually helped disperse water. Importantly, DIAL stressed that there was no structural compromise to the terminal itself.

A DIAL spokesperson explained, “A section of the external tensile fabric at the T1 Arrival forecourt adjusted under pressure, thereby aiding in water dispersal. There was no structural compromise or impact to other parts of the terminal.”

Ground teams acted swiftly, securing the affected area and working to restore operations. Within a few hours, most airport functions were back to normal, and authorities reported minimal long-term impact on overall airport operations.

Weather Data: How Bad Was the Storm?

The India Meteorological Department (IMD) recorded 81.2 mm of rainfall in just six hours (from 11:30 PM on May 24 to 5:30 AM on May 25). Wind speeds reached 82 km/h at Safdarjung and 76 km/h at Pragati Maidan. The temperature dropped to 19.8°C, which is nearly 7°C below normal for this time of year.

These numbers show just how severe the weather was, and help explain why even well-designed infrastructure struggled to cope.

Casualties and Broader Effects

While there were no reported injuries at Delhi Airport itself, the storm had tragic consequences elsewhere in the city. A Delhi Police officer died when the roof of the Assistant Commissioner’s office collapsed during the same storm. This highlights the broader risks that extreme weather poses to both public safety and critical infrastructure.

How Passengers Were Affected

For travelers, the roof collapse and resulting flight disruptions at Delhi Airport created confusion and inconvenience. Many passengers found themselves stranded, facing long waits and uncertain travel plans. Some expressed frustration over a lack of timely updates from airlines and airport authorities.

If you were at the airport or planning to travel during the incident, here’s what you needed to do:

1. Check Flight Status: Always verify your flight status with your airline or the official Delhi Airport website before heading out.
   2. Follow Airport Advisories: Listen to instructions from airport staff and authorities.
2. Allow Extra Time: Expect delays and congestion; plan to arrive earlier than usual.
3. Alternative Arrangements: If your flight was canceled or diverted, work with your airline to rebook or get a refund.
4. Monitor Official Channels: Stay updated through official airport social media accounts and announcements.

These steps remain important for anyone traveling during periods of bad weather or after major incidents.

Why Did the Roof Collapse?

The section that collapsed was made of tensile fabric, a material designed to be flexible and lightweight. According to DIAL, the fabric “adjusted under pressure,” which means it gave way to help disperse the water load. This design is supposed to prevent more serious damage, but the incident still caused alarm and operational problems.

Experts say that while the main structure of the terminal was not affected, the event shows how even modern airport designs can be vulnerable to extreme weather. As reported by VisaVerge.com, such incidents are becoming more common as climate patterns shift, putting extra pressure on infrastructure that was not always built to handle these new extremes.

Policy and Infrastructure Implications

The Delhi Airport roof collapse has prompted renewed scrutiny of how airports and other critical infrastructure are built and maintained. With weather events becoming more unpredictable and severe, there is growing pressure on authorities to review design standards and maintenance routines.

Key policy implications include:
– Infrastructure Review: Authorities may need to update building codes and design standards for airport terminals, especially for canopies and tensile roofs.
– Emergency Response: The incident showed the importance of quick action by ground teams and emergency personnel.
– Integrated Planning: The broader impact on city infrastructure (waterlogging, traffic) suggests a need for better coordination between airport authorities and city officials.

Historical Context: Not the First Time

This is not the first time Delhi Airport has faced weather-related structural problems. In June 2024, a similar roof collapse at Terminal 1 led to casualties and injuries. That incident prompted a review of safety protocols and emergency preparedness, but the recurrence in 2025 shows that more work may be needed.

The airport has also been dealing with runway upgrades and periodic closures, which have strained its ability to handle peak traffic. In May 2025, Delhi Airport faced mass flight cancellations and delays due to regional security tensions and airspace restrictions.
