Low pressure likely to form over Bay of Bengal

A low-pressure system may develop in the Bay of Bengal within two days, but is not likely to directly impact Bangladesh, the Meteorological Department says.

It is likely to form by Wednesday afternoon, and its trajectory will become clear over time, Meteorologist Kazi Jebunnesa told bdnews24.com on Monday.

According to a bulletin issued by the Met Office in the morning, mild to moderate heatwaves are currently affecting Khulna and Barishal divisions, as well as regions in Rajshahi, Pabna, Dinajpur, and Nilphamari. The heatwave is expected to ease in some areas.

Bagerhat’s Mongla recorded the highest temperature in the country at 38.3 degrees Celsius on Sunday, while Dhaka saw the highest temperature at 35.4 degrees Celsius.

Chattogram’s Sandwip recorded the highest rainfall of 71mm in the 24 hours until 6am on Monday. There were also showers in different parts of the country, including Nilphamari’s  Syedpur, Dinajpur, and Bogura.

According to the Met Office, day and night temperatures may drop by 1-2 degrees Celsius over Rangpur, Rajshahi, Mymensingh, and Sylhet divisions in the next 24 hours, while temperatures are expected to remain nearly unchanged elsewhere in the country.

Rain or thundershowers accompanied by temporary gusty winds are likely to occur at many places over Rangpur, Rajshahi, Dhaka, Mymensingh, Khulna, Barishal, Chattogram, and Sylhet divisions. There is also a possibility of scattered hail showers in some places.

When the mercury rises to between 36 and 38 degrees Celsius, meteorologists consider it a mild heat wave. A moderate heat wave occurs between temperatures of 38-40 degrees Celsius. A severe heat wave occurs when the temperature exceeds 40 degrees Celsius.

The long-term forecast for May predicts the possibility of one to three mild or moderate heatwaves and one to two severe heatwaves occurring anywhere in the country.
