As air pollution rose to staggering levels in Delhi, a thick cover of haze, dust and winds have enveloped the city for the fifth consecutive day today. Visibility in the national capital has also remained poor with the capital city's citizens being given warnings of severe health risks of the outside environment and have been asked to stay indoors. Health professionals have warned citizens to stay away from the huge quantities of dust and grit that the winds, recorded at a rate of 35 km per hour today, have been carrying across the city. Because of the dust carried by the winds, heat is unable to escape, sending temperatures in the national capital soaring. The weather department has recorded maximum temperature for today to be 40 degrees.
