New Delhi, Jan 8 (Agencies): A thick layer of fog engulfed the city this morning even as the cold wave continued unabated leaving Delhiites shivering and disrupting flight operations.

The minimum temperature was recorded at 4.3 degrees Celsius, the same as yesterday.

Heavy fog in the morning hours disrupted air and road traffic.

A cargo flight was diverted while the schedule of several others were affected this morning due to dense fog, an airport official said.

Fog started to descend on the airport last night and thickened around 11 PM, forcing airport authorities to implement low visibility procedures at around 11.20 PM.

The cold wave has persisted throughout this week and the maximum temperatures too has slid below 15 degrees Celsius on several days.

Tuesday was the coldest day of the season with both minimum and maximum dropping to season's lowest of 3.7 degrees and 12.7 degrees, respectively.

Low temperature coupled with icy winds have made life difficult for the people and the capital has recorded at least three cold-related deaths since December 26.

According to Met statistics, the record for the highest maximum for the month of January was 32.5 degree Celsius recorded on the 28th of 2004. The record minimum is -0.6 degree Celsius recorded on 16th of the month in 1935.
