A moderate to strong cold wave, which is likely to blow over the capital and northern regions, will bring night temperatures down to between four and eight degrees Celsius, paralysing life in those areas with shivering cold. The second wave will bring mild to moderate weather elsewhere in the country, with temperatures likely to be between six and ten degrees Celsius, experts at the met department said in a recent met office bulletin.

The first cold wave that swept over the country claimed nearly 60 lives.

Experts concluded that the density of fog might increase from the second week of January after they reviewed weather conditions in December and analyzed satellite and radar data.

"A drop in temperatures in January is a normal phenomenon in our country," said Arjumand Haibib, the deputy director of the met office. "The present weather situation will not continue longer than the next three to four days and the temperature will start falling," she added.

The forecast also noted that rain in January is likely to be less than normal, based on 88 percent less than normal rainfall in December. Cold temperatures during December have also been less than expected because western jet air has stayed above 18 thousand feet in space.
