North India is currently grappling with dense fog conditions that are disrupting air travel and exacerbating an ongoing cold wave, authorities and meteorologists report. The thick fog, which has severely reduced visibility, has led to multiple flight cancellations and delays at major airports, including Delhi, Chandigarh, and Jaipur, affecting thousands of passengers.

The phenomenon, typical during the winter months in northern plains, occurs due to a combination of low temperatures, high humidity, and calm winds, creating ideal conditions for fog formation. Meteorological departments have issued warnings, urging commuters and travelers to exercise caution, especially during early mornings and late evenings when visibility is at its lowest.

Several flights were delayed or diverted as airport authorities struggled to maintain safe operations. Air traffic controllers have implemented restrictions on take-offs and landings, prioritizing passenger safety. Ground transportation is also affected, with slow-moving traffic and multiple minor accidents reported on highways connecting Delhi to neighboring states like Haryana, Punjab, and Uttar Pradesh.

The persistent fog has coincided with a cold wave, bringing temperatures well below normal across the region. Delhi has reported early morning temperatures dipping near 4–6°C, while some parts of Punjab and Haryana are experiencing even colder conditions. Residents are advised to wear warm clothing, limit outdoor exposure, and take necessary precautions for the elderly and children who are most vulnerable to cold-related health issues.

Local authorities have activated emergency response measures, including deploying additional road safety teams, increasing visibility markers on highways, and ensuring timely updates for travelers. Airports are providing real-time flight information to minimize inconvenience and ensure passenger safety.

Health experts also warn about the potential rise in respiratory ailments, as dense fog often combines with air pollution to form smog, worsening breathing conditions, especially for individuals with asthma or chronic respiratory diseases. Proper masks, avoiding outdoor activities during peak fog hours, and using air purifiers indoors are recommended.

The ongoing weather conditions highlight the challenges faced by North India during the winter season, where dense fog and cold waves frequently disrupt transportation, daily routines, and overall public safety. Meteorologists predict that the fog may persist for the next few days, gradually lifting as temperatures rise slightly and wind conditions improve.

Travelers are strongly encouraged to check flight schedules in advance, use public transport cautiously, and follow advisories issued by local authorities. With proactive measures and awareness, residents and commuters can navigate the disruptions caused by dense fog while staying safe during the intensifying cold wave.
