Numbing cold gripped Delhi on Wednesday with the day temperature settling several notches below normal and the minimum temperature plunging to 4.4 degrees Celsius -  the season's lowest -- making the national capital colder than Dharamsala, Nainital and Dehradun.

Residents turned to space heaters and cups of hot tea and coffee to keep themselves warm as frosty winds from the snow-clad Himalayas barrelled through the plains, including Delhi. 

The cold snap is expected to strain power grids and pose challenges to homeless people.  

The Met Office has issued an orange alert for Delhi-NCR for the next two days.

The IMD uses four colour codes for weather warnings -- green (no action needed), yellow (watch and stay updated), orange (be prepared) and red (take action).

The Safdarjung observatory, Delhi's primary weather station, saw the minimum temperature plummet to 4.4 degrees Celsius from 8.5 degrees a day ago.  

Delhi's minimum temperature was lower than that of Dharamsala (5.2 degrees), Nainital (6 degrees) and Dehradun (4.5 degrees).

The Delhi Ridge weather station near Delhi University recorded a cold wave with a minimum temperature of 3.3 degrees Celsius, the lowest in the capital on Wednesday.

Weather stations at Lodhi Road, Palam, Jafarpur, and Najafgarh recorded a 'cold day'.  

A cold day is when the minimum temperature is less than or equal to 10 degrees Celsius below normal and the maximum temperature is at least 4.5 degrees Celsius below normal. A severe cold day is when the maximum is 6.5 degrees Celsius or more below the normal.

In the plains, the Met office declares a cold wave if the minimum temperature dips to four degrees Celsius or when the minimum temperature is 10 degrees Celsius or below and is 4.5 notches below normal.

A severe cold wave is when the minimum temperature dips to two degrees Celsius or the departure from the normal is more than 6.4 degrees Celsius. 

A layer of fog also lowered visibility to 250 metres, affecting the movement of road and rail traffic.

At least 19 trains to Delhi were delayed by one-and-a-half to four-and-a-half hours due to the foggy weather, a Railways spokesperson said.

The India Meteorological Department (IMD) shared satellite images that showed a thick layer of fog over the Indo-Gangetic plains and adjoining central and eastern parts of the country.

According to the weather office, 'very dense' fog is when visibility is between 0 and 50 metres, 51 and 200 metres is 'dense', 201 and 500 metres 'moderate', and 501 and 1,000 metres 'shallow'.

"A cold wave is prevailing in Delhi and maximum temperatures are also low, leading to cold day conditions. Most places are likely to record maximum temperatures between 13 degrees and 15 degrees Celsius," senior IMD scientist RK Jenamani said.

However, there has been an improvement in Delhi's fog condition, he said.

"Cold wave and cold day conditions are predicted to continue for the next 24 to 48 hours though there will be some improvement under the influence of a fresh Western Disturbance, which is likely to affect northwest India starting January 7," Jenamani said.

The senior meteorologist said similar conditions persist across north India, including Punjab, Haryana, Rajasthan, Uttar Pradesh and Bihar.

Day temperatures in these states are likely to remain much below normal. Cold day and severe cold day conditions are predicted to wallop Uttar Pradesh. Maximum temperatures in the state will remain 10 to 12 degrees Celsius below normal, the IMD official said.

North Rajasthan is reeling under severe cold wave conditions, with Churu recording a minimum temperature of minus 0.9 degrees Celsius.
