Delhi's air quality has improved, leading the Commission for Air Quality Management (CAQM) to revoke Stage III Graded Response Action Plan (GRAP) measures. The Air Quality Index (AQI) dropped from 380 to 236. However, Stage I and II GRAP restrictions remain in effect across the NCR to prevent further deterioration. Separately, dense fog and poor visibility caused 66 flight cancellations at Delhi airport, with temperatures hovering around 11°C and expected to remain low.
