Dense fog returned across large parts of north India on Saturday following unseasonal rainfall on Friday, which caused a drop in temperatures and disrupted daily life and transport services. Punjab and northern Rajasthan reported significant fog, reducing visibility during early morning and late-night hours, while Haryana also experienced foggy conditions affecting road and rail traffic. Cold, dry north-westerly winds kept temperatures low, with daytime chill persisting in several regions.

Weather expert Devendra Tripathi noted that fog extended into Delhi-NCR, central Uttar Pradesh, and northern Madhya Pradesh, though conditions were slightly better than previous days. Parts of the Indo-Gangetic plains, including eastern Uttar Pradesh, Bihar, Jharkhand, and Chhattisgarh, saw modest daytime temperature improvements despite lingering cold.

In contrast, southern India is bracing for a weather change. A developing system over the south is expected to bring heavy rainfall to coastal Tamil Nadu, with light, scattered showers possible in interior Tamil Nadu, Kerala, and south interior Karnataka. Parts of Maharashtra, including Pune, Sangli, Satara, Kolhapur, Solapur, Jalna, Beed, and Hingoli, may see cloudy skies, while eastern and central regions such as Patna, Ranchi, Jamshedpur, Raipur, Jabalpur, Rewa, Singrauli, and Varanasi could experience cloud cover without significant rainfall or temperature changes.

The dense fog disrupted flight operations at Delhi’s Indira Gandhi International Airport and Hindon Airport. Delhi Airport issued a passenger advisory urging travelers to check real-time updates, while IndiGo warned that operations at both airports could remain slower than usual due to low visibility, offering rebooking and refunds for affected passengers.

Authorities advised commuters in northern fog-prone areas to exercise caution and urged residents and farmers in southern states to stay alert for potential rain-related disruptions.
