New Delhi, Jan 19: The residents of the national capital woke up to a foggy morning on Tuesday with visibility levels recorded at 200 meters at Safdarjung and Palam, affecting the movement of traffic in Delhi. The lowest temperature was recorded at the Ayanagar station, which registered a minimum temperature of 5.9 degree Celsius, the India Meteorological Department (IMD) said.
On Monday, the minimum temperature in the national capital stood at 9 degrees Celsius, two notches more than normal, due to partly cloudy weather and easterly winds which are not as cold as northwesterly winds.

According to the IMD, very dense fog is when visibility is between 0 and 50 metres. In case of dense fog, visibility is between 51 and 200 metres, moderate 201 and 500 metres, and shallow 501 and 1,000 metres.
