The Bangladesh Meteorological Department (BMD) forecast light to moderate rain or thunder showers accompanied by temporary gusty wind at many places across the country over the next 24 hours, beginning at 9am on Sunday.
"Light to moderate rain or thunder showers accompanied by temporary gusty wind is likely to occur at a few places over Mymensingh, Sylhet, and Chittagong divisions," according to a BMD bulletin on Sunday morning.

Monsoon is less active over Bangladesh and moderate over the North Bay, it said, adding that a low-pressure area is likely to form over the North Bay and adjoining Central Bay of Bengal around Wednesday.
