The country may experience moderate to heavy rain in the next three to four days as a depression has formed over Bay of Bengal.
The Met office asked maritime ports to hoist local cautionary signal number-3.
Due to a depression over Bay of Bengal, many parts of the country may face light to heavy rain from today, said meteorologist Abdur Rahman Khan.
It may fade after a day or two, but rain may continue across the country, as monsoon will be active, he said.
The Met office predicts light to moderate rain and thunder showers accompanied by temporary gusty wind in places in Khulna, Barishal, Chattogram and Sylhet divisions, and at one or two places in Rangpur, Rajshahi, Mymensingh and Dhaka divisions.
