Field-level officers of the coastal districts, as well as the local police, Ansar, Border Guard Bangladesh, and Cyclone Preparedness Program (CPP) volunteers are on standby for emergency response, he said during an official meeting on cyclone preparedness at the Secretariat on Monday.
Cyclone Yaas is not likely to cause any major damage to the coastal areas of Bangladesh, as it has not intensified further and is moving west-northwest, according to the state minister.
“We are free from tension as of now, as the cyclone is now centred about 500km away from the coast of Odisha and 605km away from the coast of Bangladesh. It is likely to move northwest to Odisha.
“We hope the storm will have no major impact on the Bangladesh coast, which is likely if it maintains its course,” he said.
