Delhi faced dense fog on Saturday morning, January 17, 2026, causing low visibility and delays at Indira Gandhi International (IGI) Airport. Passengers were advised to check their flight status before traveling. The India Meteorological Department (IMD) reported a slight rise in minimum temperature to 7°C from 4°C on Friday. Despite this, visibility remained poor, affecting road, rail, and air traffic. Delhi's air quality remains a serious concern. The Central Pollution Control Board (CPCB) recorded an Air Quality Index (AQI) of 368 at 7 a.m., classifying it as "very poor." On January 14, the Sub-Committee on the Graded Response Action Plan (GRAP) met to review air quality and forecasts. They noted that the AQI is rising and expected to worsen to the "severe" category soon due to poor weather conditions and weak winds. The committee called for strict implementation of Stage-III actions of GRAP along with ongoing Stage-I and Stage-II measures across the National Capital Region (NCR). This nine-point action plan involves Pollution Control Boards (PCBs) and the Delhi Pollution Control Committee (DPCC) working to curb pollution immediately. The measures aim to protect residents as cold weather and pollution combine to create tough conditions in Delhi.
