The city's average air quality index was 399 on Friday, just two notches below the severe category. Following this, at a review meeting, the GRAP subcommittee directed that authorities in Delhi-NCR implement curbs under stage III of the anti-pollution plan with immediate effect.
It also stated that due to calm winds and stable atmospheric conditions, the AQI is likely to move into the severe category.
According to GRAP, if the AQI reaches the severe category, restrictive actions under Stage III must be invoked at least three days in advance.
