The Bangladesh Meteorological Department has warned that a new cold wave may sweep across several regions of the country starting Wednesday. The cold spell is expected to last two to three days and may be accompanied by fog. The department said that the intensity of winter, which had recently eased, is likely to increase again.

According to the synoptic situation, an extension of the subcontinental high-pressure zone lies over West Bengal and adjoining western Bangladesh, while the seasonal low pressure is positioned over the southern Bay of Bengal. The forecast indicates that nighttime temperatures across the country may fall by 1 to 2 degrees Celsius, with daytime temperatures also dropping slightly. The temperature decline may continue until January 16.

At 9 a.m. today, the lowest temperature in the country was recorded at 8 degrees Celsius in Tetulia, Panchagarh, while Dhaka registered 15.5 degrees Celsius. The Met Office has cautioned that cold and foggy conditions could persist for several days.
