A powerful spell of heavy rain, gusty winds, and thunderstorms lashed Delhi-NCR early Sunday, bringing much-needed relief from the intense summer heat. However, the downpour also led to waterlogging in several parts of the city. The weather shift followed a red alert issued by the India Meteorological Department (IMD), warning of severe thunderstorms, rain, and strong winds. Authorities have urged residents to stay indoors, avoid open spaces, and not seek shelter under trees for safety.
