Large parts of North India continue to reel under dense fog and an intense cold wave, significantly disrupting daily life and transportation across the region. Major cities including Delhi, Chandigarh, Lucknow, Jaipur, and parts of Punjab, Haryana, and Uttar Pradesh have reported severely reduced visibility during early morning and late-night hours, leading to delays and cancellations in road, rail, and air travel.
Weather authorities attribute the persistent fog to stable atmospheric conditions, low wind speeds, and high moisture levels, combined with plunging temperatures. Several areas recorded near-zero visibility at key transit points, prompting authorities to issue advisories for motorists to drive cautiously and use fog lights. National highways and expressways witnessed slow-moving traffic, while numerous trains ran behind schedule due to poor visibility along major rail corridors.
Air travel was also affected, with flights delayed or rescheduled at northern airports as runway visibility dipped below safe operating limits during peak fog hours. Airport operators activated low-visibility procedures to maintain safety while minimizing disruptions.
The cold wave accompanying the fog has further added to public discomfort, with minimum temperatures dipping well below seasonal averages in many regions. Health officials have advised people, especially the elderly and children, to take precautions against cold-related illnesses and limit exposure during early morning hours.
Meteorological departments have indicated that foggy conditions are likely to persist over the next few days, particularly during night and early morning periods. Authorities remain on alert, coordinating with transport agencies to manage disruptions while urging citizens to stay informed through official weather updates and follow safety advisories during adverse conditions.
