The Indian Meteorological Department has forecast shallow fog in Delhi today with the minimum temperature expected to drop to 7 degrees.
Over the last week, dense fog covered several parts of Northern India, with the temperatures dropping drastically in Delhi, Punjab, Uttar Pradesh, Rajasthan and Himachal Pradesh. Reduced visibility has affected travel by train, road and air.
On Friday, 15 trains were cancelled, 28 were delayed and 9 have been rescheduled due to dense fog and low visibility.
Delhi's air quality had breached lowest levels in November prompting the government to shut down schools and halt construction work in Delhi and adjoining areas.
