In Bihar, Army troops were in place to offer help to the local administrations in their rescue and relief works, a Home Ministry official said tonight.
Three helicopters were also kept on standby to help rescue the marooned people in Bihar, where nine districts have been hit by flood.
In Uttar Pradesh, two helicopters were placed at the disposal of the state government.
Rising water levels in the rivers of Uttar Pradesh has wreaked havoc in different parts of the state even as the Centre issued an "unprecedented flood situation" warning for the Rapti, which is flowing above the danger mark.
