Bhubaneswar: A low-pressure area is likely to form over east central Bay of Bengal during next 24 hours that would bring rainfall to several parts of Odisha, said Indian Meteorological Department (IMD) on Tuesday.
It would intensify into a depression and move west north-westwards towards north Andhra Pradesh and south Odisha coasts during subsequent 48 hours, it said.
Under its influence, extremely heavy rainfall is likely to occur over Odisha and north Andhra Pradesh on 20 and 21 September.
The met department said this may lead to rise in levels in rivers Mahanadi, Brahmani, Baitarni, Rishikulya, Vamshadhara and Nagavali basins as well as Indravathi and Sabari sub-basins of Godavari Basin.
“Inflows into the reservoirs in these basins are also likely to rise. Since most of the reservoirs are filled up between 84 to 95% of their capacity in Odisha, the releases from dams if any have to be taken very carefully taking into consideration downstream flood situation and the likely rough to very rough sea conditions,” said Special Relief Commissioner’s office.
