The Chattogram District Administration (CDA) has taken all-out preparations to tackle the cyclonic storm Amphan.
Chattogram Additional Deputy Commissioner Kamal Hossain said the CDA had kept 3,998 shelters ready to face the cyclone.
He said the people of the coastal areas would be taken to the shelters if the situation deteriorated. "Volunteers are also prepared for this."
Md Misbah Uddin, deputy chief of Publicity and Publications Department of the Red Crescent Youth, Chattogram, said, "Usually, we hold meetings with the youth volunteers when the warning signal no is 4. We held a meeting about Amphan on Sunday."
He said around 2,000-3,000 volunteers were prepared for the storm.
"Normally, we keep some volunteers in our control room when the warning signal no is 5. They all work together when the warning signal reaches no 6."
The very severe cyclonic storm Amphan may cross Khulna-Chattogram coast between late at night on May 19 and May 20 evening, said a special weather bulletin of the Bangladesh Meteorological Department (BMD).
The BMD asked maritime ports of Chattogram, Cox's Bazar, Mongla and Payra to keep local warning signal no 4 hoisted.
The storm over southeast bay and adjoining southwest bay were centred about 1110km south-southwest of Chattogram port, 1050km south-southwest of Cox's Bazar port, 1025km south-southwest of Mongla port and 1010km south-southwest of Payra port, said the special weather bulletin issued at 12 pm today.
It is likely to intensify further and move in a north-northwesterly direction and then recurve north-northeastwards and may cross the Bangladesh coast.
The maximum sustained wind speed within 85kms of the storm centre is about 210kph that will rise to 220kph during gusts. The sea will remain very wild near the cyclone centre.
All fishing boats and trawlers over the North Bay and deep sea have been advised to take shelter immediately and will remain in shelter till further notice.
