According to this month’s forecast report of the expert committee, normal rainfall is expected in Bangladesh in July. One to two mild pressures may occur in the Bay of Bengal this month, one of which may turn into a monsoon depression.
Heavy rains in July could lead to short to medium-term floods in the northern, northeastern, northwestern, north-central, and central parts of the country. On the other hand, short-term flash floods could occur in some parts of the south-eastern hill basin, the report said.
In June, the country received 16.7 percent more rainfall than normal, Samsuddin Ahmed said, adding that Sylhet and Rangpur divisions received less than normal rainfall and other divisions received more than normal rainfall.
In June, the highest temperature in the country was 0.3 degrees Celsius above normal and the lowest was 0.1 degrees Celsius above normal, said the director of the Meteorological Department.
