Thunderstorms Forecast Across Bangladesh

The Bangladesh Meteorological Department has forecast the possibility of thunderstorms accompanied by rain across all divisions of the country within the next 24 hours. The agency has also indicated that nighttime temperatures may experience a slight decline during this period.

According to the morning weather bulletin issued on Sunday, residents across all eight administrative divisions—Rangpur, Rajshahi, Dhaka, Mymensingh, Khulna, Barishal, Chattogram and Sylhet—may experience temporary gusty or squally winds in isolated places. These conditions are likely to be accompanied by lightning flashes, rain, or thunderstorm activity.

The forecast further notes that while daytime temperatures across the country are expected to remain broadly unchanged, a marginal decrease in nighttime temperatures may be observed. No significant fluctuation in overall daily temperature patterns has been anticipated.

In its synoptic overview, the meteorological department stated that an extension of a western low-pressure system is currently located over West Bengal and adjoining areas. In addition, there is a possibility of the formation of a low-pressure system over the south-western Bay of Bengal and nearby regions within the next 11 May period. These atmospheric conditions are contributing to the likelihood of unstable weather across Bangladesh.

Over the past 24 hours, the highest recorded temperature in the country was 37.2°C. During the same period, the highest recorded rainfall was 26 millimetres, measured in Dinajpur.

The summary of the current forecast and recent observations is presented below:

The prevailing synoptic conditions indicate a generally unstable atmosphere over the region, which is consistent with the forecast of scattered thunderstorms. Such patterns are commonly associated with transitional weather systems influenced by nearby low-pressure activity and seasonal atmospheric changes.

Authorities have advised that localized gusty winds and lightning activity may occur during thunderstorm episodes. However, no additional warnings or extreme weather alerts beyond the stated forecast have been issued in the bulletin.

The overall outlook suggests mixed weather conditions across the country, with rainfall activity expected to be uneven and temperature trends showing limited variation during the forecast period.
