"Though water receded in several rivers, the plight of people sheltered on high river embankments and other places have worsened due to fresh rainfall," Special Relief Commissioner (SRC) P K Mohapatra said.
Different parts of the state, mainly falling in northern region, were lashed by rains since last night, while water level in rivers like Mahanadi and Baitarani went down, he said.
The fresh rainfall caused by low pressure is unlikely to aggravate the flood scenario as it would be confined mainly to northern districts like Mayurbhanj, the SRC said.
