Shamsuddin Ahmed, director of the meteorological department in Dhaka, said that a stormy weather will persist in many part of the country for next 12 hours due to the influence of the cyclone. Earlier, Minister Kiren Rijju has issued notification to the North Eastern States to stay safe indoors.
The cyclone formed after monsoon rains triggered floods and landslides in Sri Lanka, off India's southern tip. The nation has not seen such a natural disaster in the past 14 years ever since Tsunami hit the island nation. A 5-6 feet storm surge is expected to inundate low lying areas including Chittagong, Cox's Bazar, Bhola, Jalakhati, Barisal and Noakhali. Authorities scrambled to evacuate over half a million people from the coastal areas. India has already sent some remedies including food and medicines.
Cox's Bazar has for years been home to hundreds of thousands of Rohingya, a stateless minority.
More than 1,000 shelters have been set up for evacuees, government officials told the Associated Press, and more than 20,000 volunteers were ready to aid people moving from the at-risk areas.
At least 16,010 homes in the camps were destroyed or damaged by the cyclone, Sahany said.
Some of the worst damage was at camps housing the 300,000 Rohingya refugees living in Cox's Bazar, many of them in flimsy huts.
Omar Farukh, a community leader in Kutapalong camp, said conditions were dire: "Now we're in the open air".
Dozens of villages in the districts have reportedly been flooded and many susceptible houses have been damaged fully or partially.
A total of 61 persons have been injured during the storm - 60 in Cox's Bazar and one in Rangamati, added Additional Secretary Mostafa.
Authorities in Cox's Bazar and neighbouring Chittagong district evacuated 350,000 people from low-lying areas before the storm blew in from the Bay of Bengal on Tuesday morning.
Cyclone Mora left at least seven people dead and damaged almost 60,000 houses, displacing around 56,000 families when it hit Bangladesh a day ago, officials said on Wednesday. All flights in and out of Chittagong's Shah Amanat International Airport were also cancelled.
