The Bangladesh Meteorological Department on Tuesday, April 28, 2026, advised Chattogram, Cox’s Bazar, Mongla, and Payra seaports to hoist local cautionary signal number 3 due to variations in air pressure over the Bay of Bengal. Fishing boats and trawlers in the northern Bay have been instructed to stay close to the coast and proceed with caution. The forecast also indicated partly cloudy to cloudy skies over Dhaka and surrounding areas, with chances of rain and thunderstorms.

The department predicted rain with gusty or squally winds and lightning across several divisions, including Dhaka, Mymensingh, Sylhet, Rangpur, Rajshahi, and Chattogram. Moderate to heavy rainfall may occur in parts of Dhaka, Mymensingh, and Sylhet, with a slight drop in day and night temperatures nationwide. Extended forecasts for Wednesday and Thursday suggest continued rainfall and thunderstorms across most regions.

Meteorologist Dr. Md. Bazlur Rashid said rainfall has eased recent heat conditions and that no heatwave is expected until early May. Earlier heatwaves had affected multiple districts, with Rajshahi recording 40°C last week.
