People in Delhi woke up to another cold morning as the temperature remained below normal level and a thick blanket of fog engulfed the national capital on Thursday.
The maximum and minimum temperatures were recorded at 21 degree Celsius and 5 degree Celsius respectively.
Foggy weather in Delhi disrupted the rail traffic as well. According to latest report compiled by the Indian Railways, as many as 11 trains were rescheduled after getting delayed for at least by an hour.
Jayanagar-New Delhi S Sainani Express, Ghazipur-Anand Vihar Express and Poorvottar Sampark Kranti Express were delayed by 1.30-hr, 2 hours and one hour respectively.
Due to low visibility, Bhubaneswar Duronto Express was delayed by five hours while Poorva Express and Puri-New Delhi Purushottam Express were delayed by three hours each.
Fog and chill are likely to persist with little hope for improvement in the quality of air and visibility, particularly during the morning hours.
The Air Quality Index (AQI) at Mathura Road was docking at 346 in the morning with particulate matter (PM) 2.5. At Dhirpur, the Air Quality Index was 297 while in Pitampura area it dipped to 'very poor' category at 355.
The Air Quality Index between the range of 51 and 100 is considered as satisfactory, 101-200 is moderate; 201-300 falls under the category of poor. AQI in the range of 300-400 is considered as 'very poor' and range between 401-500 falls under the category as 'hazardous.'
AQI near Pusa Road, Airport Terminal 3 and Chandni Chowk stood at 346, 357 and 342 respectively.
"The haze and fog will continue to persist during the early morning and late evenings for the next couple of days," said the Centre-run System of Air Quality and Weather Forecasting and Research (SAFAR).
People have been advised to avoid prolonged or heavy exertion.
"Go for a short walk instead of a jog and take more breaks. Stop any activity level if you experience any unusual coughing, chest discomfort, wheezing, breathing difficulty, or fatigue," advised SAFAR.
"If the room has windows, close them. If the air conditioner provides a fresh air intake option, keep that closed. Avoid burning of wood, candles or incense. Keep the room clean - don't vacuum. Do wet mopping to reduce dust," the SAFAR advisory further read.
Delhi, which is home to approximately 19 million people, is reeling under the threat of high air pollution. The region faced a major air quality crisis last year as pollution levels shot through the roof and even forced the shutdown of schools.
Delhi Chief Minister Arvind Kejriwal had described the capital as a "gas chamber" and local administration was compelled to declare it a public health emergency.
