Dhaka, Dec 15, (V7N) - The Bangladesh Meteorological Department (BMD) has forecast that the mild cold wave sweeping across parts of the country, including Panchagarh, Rajshahi, Jessore, and Chuadanga districts, may persist in the coming days. The weather across the country is expected to remain dry, with temporary cloud cover. Additionally, moderate to dense fog may occur in parts of the country during the night and early morning hours.

According to the 72-hour weather forecast issued on Saturday (December 14), the synoptic situation indicates that an extended high-pressure system over the subcontinent is affecting areas near West Bengal and adjacent regions. The usual seasonal low-pressure system is situated over the southern Bay of Bengal, with its extension reaching the northern Bay of Bengal.

Under these conditions, the weather is expected to remain dry across the country for the next 72 hours, with partial cloud cover. However, moderate to dense fog may develop in various parts of the country, especially from midnight to early morning. The ongoing mild cold wave, which is affecting the northern districts, including Panchagarh, Rajshahi, Jessore, and Chuadanga, is likely to continue for some time.

According to experts, cold waves usually occur when high-pressure systems in the upper atmosphere bring cooler air from the northern regions, leading to a dip in temperatures. These cold waves are more common during the winter season, but the continued presence of fog may amplify the chilling effects, making the temperature feel even lower. Experts suggest that the ongoing cold wave is part of the typical weather patterns for December, though it is relatively mild compared to extreme cold waves experienced in previous years.

In terms of temperature trends, while daytime temperatures are expected to rise slightly on Sunday, it is anticipated that the nighttime temperatures will dip a little further. This trend could continue until Monday, when both day and night temperatures may experience a slight increase.

Health and agriculture experts are advising people to take precautionary measures, especially during the morning and night when fog and cold winds are more intense. The cold temperatures, combined with the fog, can pose health risks such as respiratory issues, especially for the elderly, children, and those with pre-existing health conditions. Moreover, the cold weather could also affect farmers, particularly those growing crops that are sensitive to low temperatures.

Experts suggest that, while the cold wave is not extreme, it is still important for the public to stay warm and maintain proper indoor ventilation. They also recommend avoiding outdoor activities in the early morning and night when fog is thickest.

In summary, the weather is expected to remain dry with partial cloud cover across Bangladesh over the next few days, while the mild cold wave continues in the northern and southwestern parts of the country. The presence of fog during the night and morning hours is likely to contribute to the chilly weather, and experts warn of potential health risks.
