Intense cold conditions persisted in Delhi on Saturday pushing night temperatures below 4 degree Celsius even as Delhiites woke up to a bright and sunny morning.

The lifting of the heat-trapping cloud cover over Delhi coupled with the icy northerly winds sweeping the city resulted in the minimum temperature plummetting to 3.6 degree Celsius, three notches below normal.

The minimum temperature on Friday was 4.8 degrees Celsius, while the maximum was recorded at 19.7 degrees Celsius, the weather office said. Night temperatures have risen marginally in the last two days due to the cloud cover.

There was shallow fog in the morning, but it did not affect rail, road and air traffic. The visibility dipped to 600 mt at around 7 am, and later improved as the sun came out.

All international and domestic flights operated on schedule as runway visibility levels were normal in the morning hours, airport sources said.

Met office said the cold wave conditions are likely to persist for a few more days with the minimum temperature in Delhi expected to hover around 3 degree Celsius. The mornings are also likely to be foggy.
