Biting cold gripped Chuadanga as the district's lowest temperature was recorded at 9.0 degrees Celsius on Friday.
Temperature between 8 to 10 degrees Celsius is considered a mild cold wave, 6 to 8 degrees Celsius a moderate cold wave and less than 6 degrees Celsius a severe cold wave.
Severe cold with frosty winds from the north and dense fog is disrupting daily life in Chuadanga. The low-income people who get by working every day are being hit hardest.
Many were seen making fires along the roadsides to keep warm. Most people are staying home unless there is an emergency.
"A biting cold spell has continued to sweep across the district. Winter is being felt severely due to the foggy environment and frosty air. Such conditions may last for a few more days. Also, the mercury may drop even further," said Rakibul Hasan, officer-in-charge of the Chuadanga met office.
Also, the number of diarrhoea and pneumonia patients – mostly children and elderly – is increasing in the hospitals of Chuadanga.
A mild cold wave is sweeping through four other districts – Naogaon, Dinajpur, Panchagarh and Jashore – and it may continue, the Bangladesh Meteorological Department (BMD) said on Friday.
The highest temperature was recorded at 26.5 degrees Celsius in Cox's Bazar and Sitakunda.
"The weather may remain dry with a temporary partly cloudy sky over the country in the next 24 hours. Besides, moderate to thick fog may occur over the country from midnight till morning and it may continue till noon at places," the BMD said.
