The Bangladesh Meteo-rological Department says the country is likely to see more rain amid the ongoing flooding in eleven districts.
There will be no respite from rain over the next three days, said meteorologist Manowar Hossain.
"We don't foresee any development in the rainfall situation, especially in the eastern or northeastern region and in the country in the next 72 hours," he said in a briefing on Friday.
"The [flood] situation in Feni [is so severe] that we couldn't collect records from our office," he said.
The meteorologist said that rainfall would start to ease after Monday.
The Ministry of Disaster Management and Relief reported that the floods have caused 13 deaths in seven districts from Tuesday to noon on Friday.
As per information from the ministry, 584 unions in 77 Upazilas of Feni, Cumilla, Chattogram, Khagrachhari, Noakhali, Moulvibazar, Habiganj, Brahmanbaria, Sylhet, Lakshmipur and Cox's Bazar were hit by flooding.
The sudden floods have affected more than 4.4 million people in those 11 districts. At least 887,629 families were trapped by floodwater.
The Flood Forecast and Warning Centre of the Bangladesh Water Development Board, however, says the flooding situation in five districts including Cumilla and Feni was gradually improving. But meteorologist Manowar Hossain saw no possibility of reduced rainfall in the flood-affected districts.
"[The flood situation] will remain the same as it is now. We already said in our long-term forecast that these areas will undergo short-term flooding," he said.
As per the regular BMD bulletin, the Rangpur, Rajshahi, Dhaka, Mymensingh, Khulna, Barishal, Chattogram and Sylhet divisions will experience light to medium rain and thunderstorms with gusty winds from 9am on Friday.
Some parts of the country will also see medium to heavy or very heavy rain.
Pabna's Ishwardi saw the most rainfall - 164 mm - in the 24 hours to 6am on Friday. Elsewhere, 151 mm of rainfall was recorded in Cox's Bazar, 143 mm in Chattogram's Ambagan, 97 mm in Chattogram's Sitakunda, and 90 mm in Lakshmipur's Ramgati.
Usually, 1-10 mm of rainfall in 24 hours is considered light rain, 11-22 mm is moderate rain, 23-43 mm is moderately heavy, 44-88 mm is heavy rain and more than 88 mm is considered very heavy rainfall. —bdnews24.com
