The national capital and its adjoining suburbs were blanketed in a grey haze this morning, with visibility dipping to 300 meters at some places, causing train delays and slowing down flight operations. Some 30 trains coming to Delhi and 30 flights landing or taking off from the Delhi airport were delayed, according to officials. Poor visibility also caused heavy traffic snarls at many places in Delhi and NCR. The saving grace was the absence of hundreds of school buses on the roads. The situation is likely to worsen on Thursday as the weather department has predicted "dense to very dense fog very likely" at many places in Punjab, Haryana, Chandigarh, Delhi, Rajasthan and western Uttar Pradesh. don't forget to share subscribe like comment
