A fresh spell of rain is likely to lash Odisha over the next three days due to formation of a low pressure area on Bay of Bengal, the meteorological centre here said.
Last week, too, the state had been pounded by a downpour, affecting at least nine districts in the southern and the western regions, it said.
According to the meteorological centre, the low pressure area over northwest Bay of Bengal and the adjoining West Bengal and Bangladesh coasts may trigger light to moderate rain or thundershower in most parts of the state.
Heavy to very heavy rain is expected in the next 24 hours in north coastal Odisha and other areas in the western and the northern parts of the state, including Mayurbhanj, Sonepur, Keonjhar, Balangir, Bargarh, Kalahandi, Kandhamal, Raygada, Nayagarh and Puri districts.
Similarly, extremely heavy rainfall is likely to batter parts of Bhadrak, Kendrapada, Jagatsinghpur, Kandhamal, Rayagada and Kalahandi.
The MeT centre has forecast heavy to very heavy rainfall on Tuesday and Wednesday in parts of south interior Odisha and districts such as Sundargarh, Jharsuguda, Sambalpur and Bargarh.
