Heavy Rain Warning Extended Another 24 Hours

Persistent monsoon rain continues to affect Bangladesh, prompting the Bangladesh Meteorological Department (BMD) to extend its warning for heavy to very heavy rainfall by another 24 hours. Rain has continued across much of the country since Monday morning, including in the capital, Dhaka, while several districts have already recorded significant downpours.

The latest forecast, effective from 11:00 am on Monday for the following 24 hours, warns of heavy to very heavy rainfall across six divisions—Rajshahi, Rangpur, Mymensingh, Dhaka, Chattogram and Sylhet. The weather office has also cautioned that intense rainfall may lead to waterlogging in many parts of Dhaka, where drainage systems often struggle to cope with prolonged periods of heavy precipitation.

The warning comes after a similar advisory issued on Sunday, reflecting the continued influence of an active monsoon system over the country. According to meteorologist Muhammad Abul Kalam Mallik, the renewed alert has been issued because the monsoon has become more active, creating favourable conditions for widespread and intense rainfall.

He said that between 6:00 am on Sunday and 9:00 am on Monday—a period of 27 hours—the capital recorded 110 millimetres of rainfall. Although the intensity of rain is expected to ease from Tuesday, forecasters believe this relief may be temporary. Rainfall could increase again from Thursday as the monsoon is expected to strengthen once more.

Sunday witnessed exceptionally heavy rainfall nationwide, with precipitation recorded across all regions of Bangladesh. Dhaka experienced the country’s highest rainfall that day, receiving 175 millimetres, highlighting the widespread nature of the current weather system.

The rain continued into Monday morning. Data from the Bangladesh Meteorological Department showed that between 6:00 am and 9:00 am, Cumilla recorded the highest rainfall in the country, measuring 107 millimetres in just three hours. During the same period, Dhaka received 13 millimetres of rain.

Other notable rainfall totals included 35 millimetres in Bogura, 32 millimetres in Sylhet, 23 millimetres in Mymensingh, 18 millimetres in Naogaon and 10 millimetres in Rangpur. These figures indicate that rainfall has remained widespread, although its intensity has varied considerably from one region to another.

Meteorologist Md Abdul Hamid said northern parts of the country are expected to receive comparatively heavier rainfall during the day, as weather conditions remain favourable for further showers and thunderstorms.

Heavy monsoon rainfall frequently causes disruption in Bangladesh during the rainy season. Prolonged downpours can inundate low-lying areas, trigger urban waterlogging, slow road transport and affect daily economic activities. Authorities therefore advise residents, particularly those living in flood-prone and low-lying areas, to remain alert and follow official weather bulletins as conditions may change rapidly over the coming days.

The latest forecast suggests that while rainfall may temporarily weaken early in the week, the active monsoon pattern is likely to persist, meaning further episodes of heavy rain remain possible across large parts of the country later this week.
