The India Meteorological Department said dust-laden winds with speeds up to 50 kmph breezed through the capital between 3 am and 6 am, lowering visibility to a mere 700 metres at 10 am at the Palam Observatory, close to the Indira Gandhi International Airport, as compared to 4,000 metres at 9 am on Monday.
By 3 pm on Tuesday, the overall air quality index had worsened to 260, from 162 at 4 pm on Monday.
