India Gate in the national capital disappeared into a layer of dense fog after the weather department predicted 'very dense fog' for today.

The most likely reasons behind poor air quality, as stated by SAFAR, are moderate local wind speed and low stubble burning.

According to the Indian Meteorological Department (IMD), visibility recorded in Palam at half-past six in the morning was 300 meters.

Delhi and its adjoining areas woke up to a thick blanket of fog this morning that hit the road, rail, and air traffic due to very poor visibility.

An AQI between 0-50 is marked good, 51-100 is satisfactory, 101- 200 is moderate, 201- 300 is poor, 301-400 is very poor and 401-500 is considered severe. 

Delhi Rains: The lowest minimum temperature recorded in January last year was 2.4 degrees Celsius, the IMD said.

Delhi's Safdarjung recorded minimum temperature at 7 degrees Celsius at 8:30 am today, which is likely to rise by 5.9 degrees Celsius during the next 24 hours, while the temperature in Palam is expected to rise by 5.4 degrees Celsius above 9.5 degrees Celsius recorded earlier today.

Srinagar has been covered in a blanket of snow as the temperature has dropped here. IMD had also forecasted on Friday that "fairly widespread to widespread rainfall/snowfall" is "very likely" over Jammu and Kashmir, Ladakh, Gilgit-Baltistan, Muzaffarabad and Himachal Pradesh and "isolated rainfall/snowfall" over Uttarakhand during December 11 and 12.

Yesterday, the System of Air Quality and Weather Forecasting And Research (SAFAR) predicted "very poor" air quality in parts of the national capital for two days.

In 1991, 1993, 1994, and 2007, the October MMTs were recorded at 17.6, 17.8, 17.9 and 17.5 degrees Celsius respectively, according to the IMD.
