With the chill intensifying, residents of Amritsar woke up on Tuesday to find the city engulfed in dense fog for the second consecutive day.
Commuters and even those on foot had an arduous time while traversing through the city roads.
Owing to poor visibility, many flights were delayed. Power outages were also reported due to snags in the supply lines.
The city recorded a maximum temperature of 13.8 Degrees Celsius, while the minimum was 7.8 Degrees Celsius.
The MET officials forecast extremely dense fog -- visibility reduced to 50 metres or less -- at a few places during the night and morning hours.
Power outages were reported several times during the day, causing inconvenience to residents.
Though a thick blanket of fog persisted till noon, the haze began to clear in the afternoon, only to re-appear in the evening.
Officials at the Sri Guru Ram Das International Airport said fog had severely affected operations at the Amritsar Airport.
They said just after the departure of the Jet Airways flight to Delhi around 7:30 PM on Monday, visibility dropped below 200 metres and subsequently to less than 50 metres.
Following this, Air India and Spice Jet flights from New Delhi and Uzbekistan Airways flight from Tashkent were cancelled.
Due to poor visibility throughout the day and night, flight operations were hit at Amritsar Airport, except the Uzbekistan Airways flight to Tashkent, which departed from the airport around 2:30 PM, when there was a marginal improvement of the runway visual range.
The Qatar Airways flight from Doha to Amritsar, Air India Express flight from Dubai to Amritsar and Turkmenistan Airway from Ashgabat to Amritsar were diverted to the Delhi Airport.
All other scheduled flights from New Delhi to Amritsar were also cancelled for the day.
Meanwhile, doctors in the city expressed concerns about the effects of cold wave and fog on people's health.
Dr NC Kajal, TB Hospital, said, "People, particularly children and senior citizens, should avoid unnecessary exposure to the cold weather as it can cause diseases such as pneumonia, bronchal asthma, bronchitis, allergic lung disease and chronic obstructive pulmonary disease."
"People should avoid stepping out unless they are dressed in warm clothes. Children and the elderly are at a higher risk of catching chest-related ailments," he added.
Dr NS Neki, professor of medicine, Government Medical College, advised residents to keep themselves hydrated during winters to keep diseases at bay.
"Besides chest infections, intense cold can cause serious heart trouble as blood turns cold and begins to clot. Patients can suffer stroke, coronary artery disease and myocardial infections. People should avoid rich foods and focus on consuming a balanced diet and keep themselves hydrated," he added.
