• Dense fog to disrupt air and rail travel across North India for at least two more days, with a western disturbance weakening by Tuesday.
• Over 100 flights cancelled and 500+ delayed on Sunday at Delhi's IGI Airport; train services also faced significant delays.
• Visibility dropped to 200-300 meters in Delhi, while air quality remained in the "very poor" category for the 11th consecutive day.
• The western disturbance caused snowfall in Jammu and Kashmir, Ladakh, and Himachal Pradesh, expected to ease by Tuesday.
