Delhi-NCR woke up to another challenging winter morning on Tuesday, December 30, as very dense fog enveloped large parts of the region. The India Meteorological Department has kept the orange alert in place, warning of severely reduced visibility, especially during early morning hours. Highways, flyovers and major arterial roads in south and east Delhi, along with Noida, Ghaziabad and Gurugram, remain particularly vulnerable. While visibility is expected to improve slightly by late forenoon as temperatures rise, commuters have been advised to remain cautious and avoid unnecessary early travel.
