Dhaka, Dec 15 (UNB) - Bangladesh is currently facing its first tangible cold wave of the season, with temperatures dropping sharply across various regions.
 
According to the Bangladesh Meteorological Department (BMD), a mild cold wave is sweeping over the northern and western districts, including Panchagarh, Rajshahi, Jashore, and Chuadanga.
 
This weather pattern is expected to persist over the coming days, accompanied by dense fog in many areas.
 
The Meteorological Office reported that the lowest temperatures were recorded in northern districts, with conditions expected to remain challenging through mid-December.
 
The cold wave is being driven by the extended influence of the subcontinental high-pressure area over the West Bay of Bengal and adjoining areas.
 
Meanwhile, the low-pressure system in the South Bay of Bengal, extending toward the North Bay, continues to influence local weather patterns.
 
International weather agencies have corroborated the forecasts, noting that Bangladesh is currently experiencing below-average seasonal temperatures.
 
Historical data indicates that December lows in the country typically range from 15°C to 19°C, while current readings in several districts have dropped to single digits, with Tetulia and Chuadanga recording some of the coldest temperatures.
 
Looking ahead, the BMD forecasts that nighttime temperatures may decrease slightly over the next three days, while daytime temperatures may rise marginally.
 
Moderate to dense fog is expected to persist during the early hours, especially in northern and central regions.
 
By Tuesday, both day and night temperatures may see a slight increase, offering some relief from the current cold spell.
 
International agencies also predict drier weather conditions in Bangladesh through December, with no significant rainfall expected.
 
This is consistent with the seasonal pattern, as December typically experiences the lowest rainfall of the year.
 
Weather models further suggest that the extended high-pressure system over the region may keep temperatures suppressed until late December.
 
Residents are advised to take precautions against the cold, particularly during nighttime and early morning hours.
 
Vulnerable populations, including children and the elderly, are urged to avoid prolonged exposure to the cold.
