Last night, an extensive layer of dense fog covered areas including Punjab, Haryana, Delhi, North Rajasthan, and Uttar Pradesh, as reported by the IMD. This morning, very dense fog was observed over specific locations like Amritsar, Chandigarh, Patiala, Ambala, Ganganagar, Palam, Safdarjung, and Lucknow, with visibility dropping to zero meters.

The IMD predicts that minimum temperatures will range from 3 to 7 degrees Celsius across most parts of Punjab, Haryana, Delhi, Uttar Pradesh, north Madhya Pradesh, Rajasthan, and Bihar in the coming days. Foggy conditions are expected to persist for several hours during the night and morning in Punjab, Haryana, Delhi, Uttar Pradesh, Himachal Pradesh, and Uttarakhand.

For those traveling on highways, the advice is to drive extremely carefully and use fog lights. Travelers on expressways are encouraged to consider halting their journey until visibility improves. The caution comes as dense fog poses challenges for safe driving conditions.
