New Delhi, Dec 22 (IANS): Delhiites Monday woke up to a chilly Monday accompanied with dense fog. The minimum temperature was recorded at 4.2 degrees Celsius, four notches below the season's average. It was the coldest Monday in the last five years, the Met Office said.

The thick fog reduced visibility to 50 metres, that led to the delayed arrival of 50 trains and the rescheduling of 12.

"Due to the poor visibility the arrival of 50 trains from various parts of the country to the national capital has been delayed while 12 trains have been rescheduled and one has been cancelled," said an official of the Northern Railway.

The Met Office has forecast a cloudy day ahead with dense fog in the evening.

"Monday ahead will be cloudy and fog is likely to remain through out the day," said an official of the India Meteorological Department (IMD).

The maximum temperature is likely to hover around 16 degree Celsius.

Humidity at 8.30 a.m. was 97 percent.

Sunday's maximum temperature was recorded at 15 degrees Celsius, seven notches below the season's average while the minimum temperature slumped to 6.4 degrees Celsius, two notches below the season's average.
