The water level in most of the swollen rivers in Odisha dropped below the danger level on Tuesday even as 6.4 lakh people remained marooned across 902 villages in the state, officials said.

Water Resources Department Chief Engineer B K Mishra said that most of the rivers including Subarnarekha in northern Odisha and Mahanadi in the East are flowing below the danger level.

However, the India Meteorological Department (IMD) has predicted heavy to very heavy rainfall in one or two places in Balasore, Bhadrak, Jajpur, Kendrapara, Cuttack, Jagatsinghpur, Keonjhar and Mayurbhanj districts on Tuesday and Wednesday.

Even though there has been no breach in embankment of Subarnarekha, where peak flood was witnessed on Monday afternoon, embankments of Mahanadi and its tributaries have been breached in seven places, the official said.
