The flood situation in Assam, Bihar and Uttar Pradesh showed signs of improvement on Sunday with most rivers receding even as heavy rains lashed parts of Goa, Rajasthan and Orissa, waterlogging low-lying areas and throwing life out of gear.
Heavy rains continued unabated in coastal Goa with authorities asking fishermen not to venture in the turbulent sea.
The Indian Coast Guard, too, has mounted its surveillance off-shore to pre-empt any emergency.
Incessant downpour lashed coastal Orissa also as the well-marked low pressure area over north west Bay of Bengal concentrated into a deep depression, which is likely to intensify further and move in a west-north direction and cross the north Orissa-West Bengal coast between Paradip and Digha.
Rains also caused waterlogging in many colonies and low-lying areas of Rajasthan.
Jaipur recorded a maximum rainfall of 3.5 cm since Saturday. The southwest monsoon was also aggressive in the western parts of the state with Jaisalmer, Jodhpur and Barmer recording 1-4 cm of rainfall.
The United Nations has described the current flood situation in the country as the worst in living memory.
"The sheer size and scale of flooding and the massive numbers of people affected pose an unprecedented challenge to the delivery of desperately needed humanitarian assistance," a UN statement said.
Meanwhile, the flood scene in Bihar showed signs of improvement with major rivers maintaining a receding trend, even as four more deaths were reported from Darbhanga district, taking the total toll in the current deluge to 81.
Over 11 million people spread over 4,822 villages were affected by the floods, officials said.
The situation also improved in Assam and Uttar Pradesh.
In Uttar Pradesh, the situation in about 1,100 marooned and 2,200 affected villages in 20 districts has started improving with army and PAC personnel assisting in relief and rescue operations.
The toll this season due to flood-related incidents in the state stood at 122.
Shravasti, Maharajganj, Kushinagar, Gonda, Baharaich, Ballia, Gorakhpur and Barabanki were the worst-affected districts in the current wave of floods in the state.
The flood situation in Assam continued to improve as the Brahmaputra and its tributaries receded further.
The situation in the worst-hit Dhemaji and Lakhimpur districts, however, remained unchanged as thousands of victims were in the relief camps.
Twenty-three people have lost their lives so far with more than 60 lakh affected in the current wave of floods.
On the other hand, Met officials have forecast heavy to very heavy rainfall across Maharashtra in the coming days.
In Bihar, Chief Minister Nitish Kumar made an aerial survey of the flood-affected districts of Saharsa, Supaul and Madhepura and held a meeting with top officials to review relief and rescue operations.
Union Home Minister Sivraj Patil will visit Bihar on August 7 to make an assessment of the flood situation.
