A mild cold wave is sweeping across some places of the northern region while people across the country are also experiencing the bite of chilly weather.
Country’s lowest temperature was recorded 9.6 degrees Celsius at Tetulia in Panchagarh on Friday while the mercury dipped to 14.4 degrees in Dhaka.People living in open and public spaces like bus stands and railway stations, and daily labourers and slum dwellers are suffering a lot as they cannot afford to buy warm clothes amid the biting cold.
Weather may remain dry with temporary partly cloudy sky over the country, according to the Bangladesh Meteorological Department (BMD).
Moderate to thick fog may occur over the river basins of the country and light to moderate fog may occur elsewhere over the country during midnight to morning, it said, adding that night and day temperature may remain nearly unchanged over the country.
The first spell of cold wave swept through the country in the last part of December. However, people witnessed comparatively lower cold in the first week of January.
The first spell of mild to moderate cold wave gripped Rangpur, Rajshahi, Kushtia and Jashore during December 18-31.
“Temperature may decline by a couple of days and a mild cold wave may sweep across the country, especially northern region, from Friday night and it may continue,” said Arif Hossain, a meteorologist at the BMD.A moderate cold may is likely to hit the country from January 28 and temperature may lie between 6 and 8 degrees Celsius then, he said.
The country usually faces its coldest spell in January. In 2018, the mercury dropped to 2.6 degrees Celsius at Tetulia, the lowest on record.
If the temperature is at or below 10 degrees Celsius, it is assumed that a cold wave is sweeping through. If the mercury lies between 8 and 10 degrees Celsius, it signals to a mild cold wave.
When the mercury drops below 6 degrees Celsius, it is assumed that a severe cold wave is blowing through.
