A powerful rainband named 'Ishan' is approaching Bangladesh, likely to impact 90% of the country with rain between August 4–8. The northern regions, especially Rangpur, Mymensingh, and Sylhet, may face flooding in low-lying areas. The system may bring lightning, gusty winds, and increased landslide risks in hilly areas like Chattogram and Sylhet. While the sea is expected to remain mostly calm, skies will be mostly cloudy. Weather may feel comfortable in northern areas, with humid heat in the south during rain breaks.
