The SAFAR model forecast suggests AQI is likely to deteriorate marginally to Poor category until November 30. The estimated fire counts are 147 and stubble transport-level winds are easterly. Hence, no significant stubble impact is expected in Delhi for Friday.

An AQI between 0-50 is considered `good`, 51-100 `satisfactory`, 101-200 `moderate`, 201-300 `poor`, 301-400 `very poor` and 401-500 is marked as `severe`. An AQI above 500 falls in the `severe plus` category.
