Due to low pressures, it has been raining across the coastal regions since Sunday.
According to the Met Office forecast, the rains will cause a slight drop in temperature in the next few days. The meteorologists have predicted that the northern cold breeze will enter Bangladesh from the foothills of the Himalayas through Panchagarh.
The low pressure can cause strong winds in different locations, including the coastal areas. Therefore, Chattogram, Cox's Bazar, Mongla and Payra ports have been asked to show cautionary signal 3.
The fishing boats stationed in the Bay of Bengal have been asked to navigate near the coast with caution.
Shahinur Islam, a meteorologist at the Meteorological Department, told The Business Standard, "It may rain in different parts of the country on Monday as well, after which the rain will lose its intensity. The temperature will gradually start dropping, leading to the onset of winter."
Meanwhile, according to a forecast from the Flood Forecasting and Warning Centre, the low pressure in the Bay will cause rain in different parts of India in line with the coast, and central parts of Bangladesh.
