NEW DELHI: A thunderstorm swept through Delhi-NCR, disrupting traffic and causing delays to several flights. Wind speeds reached 60–70 km/h across the city, with visuals showing multiple trees uprooted by the storm.This sudden weather change followed a day of extreme heat, as Delhi sweltered under a heat index or “feels like” temperature of 50.2°C, driven by a combination of high humidity and intense sunlight.According to the India Meteorological Department (IMD), the storm was triggered by a cyclonic circulation over Haryana and nearby areas. This system is embedded in an east-west trough extending from Punjab to Bangladesh at lower tropospheric levels. Moisture from both the Arabian Sea and the Bay of Bengal is feeding into the system, intensifying the weather conditions.
