According to a regular weather bulletin, light to moderate rain or thundershowers accompanied by temporary gusty wind is likely to occur at many places over Rangpur, Rajshahi, Mymensingh and Sylhet divisions.
The same forecast has been issued for a few places over Dhaka, Khulna, Barishal and Chattogram divisions. Meanwhile, the northern parts of the country might see moderately heavy to heavy falls at places.
The axis of monsoon trough runs through Punjab, Haryana, Uttar Pradesh, Bihar and West Bengal to Assam across the central part of Bangladesh. One of the associated troughs extends up to the North Bay.
Monsoon is fairly active over Bangladesh and weak to moderate over the North Bay, the Met Office said.
Day and night temperature may remain nearly unchanged all over the country.
