A late-night thunderstorm fueled by a western disturbance swept across Delhi on May 4, 2026, leading to the diversion of 24 flights from Indira Gandhi International Airport. The India Meteorological Department issued a red-then-orange alert for the city, citing wind gusts reaching 70 km/h that toppled ground-handling equipment and delayed numerous departures. Airlines rerouted aircraft to Jaipur, Lucknow, and Ahmedabad, with Vistara and IndiGo waiving change fees for affected passengers.
Travelers facing weather-disrupted schedules may also encounter unexpected visa or transit-document requirements. VisaHQ’s online platform enables quick checks of entry rules for alternative airports, facilitates emergency e-visas, and arranges courier services for passport renewal, helping travelers navigate weather-related detours.
Storm Impact and Future Outlook
The incident underscores the vulnerability of Delhi’s busiest airport during the pre-monsoon season. The Directorate-General of Civil Aviation instructed carriers to maintain minimum fuel reserves for 45 minutes of holding, plus an alternate airport, until May 15. Notably, the storm improved Delhi’s Air Quality Index from 175 (moderate) to 88 (satisfactory), allowing the authorities to lift Stage 1 restrictions under the Graded Response Action Plan. However, forecasters warn of another thunderstorm capable of causing further schedule disruptions on May 6.
Travelers transiting through Delhi should plan for longer connection times and monitor airline updates for gate changes. Companies may need to adopt flexible policies to accommodate potential missed flights. Continued weather volatility highlights the importance of preparedness during this period of increased atmospheric instability.
