North India is currently grappling with widespread disruptions caused by a combination of dense fog and a cold spell following recent rainfall. On January 9, 2026, fog returned across vast parts of northern India, including Punjab, northern Rajasthan, and Haryana, leading to significant reductions in visibility and impacting daily life and transport services. By January 10, 2026, winter conditions intensified, prompting the India Meteorological Department (IMD) to issue warnings for cold wave, cold day, and dense fog across north and central India, with minimum temperatures in Delhi dropping significantly. Delhi's Indira Gandhi International Airport (IGI) has been particularly affected, with numerous flights facing delays and disruptions. The airport authorities issued passenger advisories, confirming that flight operations are being conducted under CAT III conditions, which, while enabling landings in low visibility, inevitably lead to slower operations and cascading delays across schedules. Major airlines like IndiGo and Air India have also released travel advisories, requesting passengers to monitor their flight status before traveling to the airport due to the fluctuating visibility and potential for further operational slowdowns. Beyond Delhi, other northern cities have also experienced similar impacts on air travel. Adding to the challenging conditions, Delhi's air quality continues to remain in the 'poor' to 'severe' categories, exacerbating the difficulties for residents and travelers.
