However, the heatwave may ease by Friday, said BMD Meteorologist Md Abdul Hamid Mia.
Meanwhile, the BMD has forecast light to moderate rain or thundershowers with squally or gusty winds and lightning in some places in the Rangpur, Mymensingh, Chattogram, and Sylhet divisions and one or two places in the Rajshahi, Dhaka, Khulna, Barishal divisions on Wednesday and in some places in the Rangpur, Dhaka, Mymensingh, Chattogram, and Sylhet divisions and one or two places in the Rajshahi, Khulna, and Barishal divisions on Thursday.
