Delhi is reeling under an intense heatwave, prompting authorities to issue a red alert after the heat index reached a dangerous 51.9°C. The India Meteorological Department warns the extreme heat will continue until June 13. Areas like Ayanagar, Palam, and Pitampura recorded temperatures above 43°C. With humidity and dry northwesterly winds worsening conditions, citizens are urged to stay indoors, avoid direct sunlight, and stay hydrated. A western disturbance expected on June 13 night may bring relief with light rain or thunderstorms.
