Delhi Chokes: AQI Crosses 400, Flights Grounded Amid Toxic Haze & Fog

• Delhi's AQI remains 'very poor' to 'severe', with several areas exceeding 400, indicating a persistent toxic haze.
• GRAP-4 restrictions are in effect but proving ineffective due to biting cold and sluggish wind speeds.
• Over 95 flights were cancelled at IGI Airport on Sunday due to low visibility and dense fog, following 120+ cancellations on Saturday.
• IMD has issued Orange and Yellow alerts for dense fog across North India, with 'Cold Day' conditions expected in Delhi and UP.
• Relief is anticipated around December 23-24 as increased wind speeds are expected to disperse pollutants, improving air quality.

Why It Matters: Delhi battles severe pollution and fog, grounding flights and prompting health warnings, with slight relief expected soon.
