After making landfall in Bangladesh's Barisal-Khulna-Chittagong coastal region, the cyclonic storm Roanu has weakened and turned into a land depression,    

"Now it is lying in Feni, Khagrachhari, Sitakunda [of Chittagong] area and Indian state of Tripura," Muhammad Mohiuddin, an observer at the Dhaka Met Office, told The Daily Star at 7:45pm. 

As the storm weakened, the cautionary signal was lowered to 3 at all the Maritime ports.

While crossing the coastline, the storm had a speed of 60-80 kilometre per hour while heading east-northeastwards, he said, adding that the rainfall will continue there for next 24 hours due to impact of the cyclone.

Most places of the country witness rain and thunder showers accompanied by temporary gusty and squally wind since early morning.

At least 20 people were killed, 100 injured and four went missing in Chittagong, Bhola, Cox's Bazar, Noakhali and Patuakhali districts as Cyclone Roanu made its impact across the country.
