"The saw mill made from tin and wood were taken apart by strong winds," said Megnad Tangchanggya, assistant meteorologist at Patenga Met Office. "There is no possibility of a tornado or cyclone."
However, heavy showers will continue over Chittagong division, said a Met Office forecast.
There are also fears that the downpour would lead to more landslides in the hilly areas of Chittagong and Sylhet.
