Dense fog settled over large parts of Delhi-NCR on Tuesday morning, significantly reducing visibility and causing disruption to road, rail and air services. The Ghaziabad neighbourhood of Indirapuram was among the worst affected, with commuters reporting slow-moving traffic and delays on key arterial routes.
Dense fog Delhi-NCR disrupts travel and commutes
Visibility in several areas dropped below 50 metres during the early hours, prompting traffic police to urge road users to drive carefully and use fog lights. Motorists travelling on the expressways and within city limits faced long delays as speed was reduced and sight lines were severely curtailed.
Airport authorities warned passengers to check flight statuses and arrive well in advance, after a number of departing flights were delayed. Rail services also reported schedule adjustments, with some trains running late due to slower operating conditions and safety precautions.
Low temperatures and health advisories
The arrival of the dense fog followed a spell of lower overnight temperatures, which helped trap moisture close to the ground. Local health officials advised those with respiratory conditions, the elderly and young children to limit outdoor activity while the fog persists. Simple measures such as wearing a mask, keeping warm and avoiding strenuous activity outdoors were recommended.
Air quality indices in parts of the national capital region showed a deterioration compared with clearer days, although officials emphasised that immediate health impacts vary according to individual susceptibility. People were advised to monitor real-time air quality readings and follow guidance from health services if symptoms such as coughing or breathlessness develop.
Authorities issue practical guidance
Traffic police issued directives to maintain safe distances between vehicles and to switch on hazard lights if visibility falls suddenly. Bus operators and ride-hailing services cautioned passengers that journey times could increase. Commuters were encouraged to allow extra time for travel, use alternate routes where possible and follow updates from transport providers.
Schools and colleges continued normal operations in most districts, though some institutions reported late arrivals as parents opted to delay their journeys until visibility improved. Municipal services said they were monitoring conditions closely and stand ready to respond to incidents that may arise due to the fog.
Outlook and what travellers should know
Meteorological departments forecast that the fog will gradually lift during daylight hours as temperatures rise. However, similar conditions may recur during the coming nights while cold air lingers. Travellers should check official updates before setting out, carry warm clothing and keep mobile phones charged for receiving travel alerts.
For residents of Indirapuram and other affected neighbourhoods, staying informed through local news bulletins, traffic feeds and official advisories remains the best way to minimise disruption and stay safe while the dense fog affects the region.
