However, the air quality of Delhi was recorded as 'very poor', the central government-run SAFAR said Monday, adding the pollution level is expected to reduce due to thunderstorms.

"Moisture incursion from the Arabian Sea is ongoing and it is leading to increased thunderstorm activity in northwest India. Thunderstorms with gusty winds can lead to sudden peaking of dust in isolated places for a brief period of time in northwest India including Delhi," SAFAR said.
