Flooding has forced almost 100,000 people to leave their homes after torrential rain lashed the southern Indian state of Andhra Pradesh, officials say.
The death toll in rain-related incidents has risen to 25, with more than 1,500 homes damaged.
Rescue teams have helped more than 2,000 people stranded in flooded regions, a navy release said.
The rains were triggered by a cyclone which hit Andhra Pradesh last week.
Cyclone Nilam hit parts of the state and neighbouring Tamil Nadu with winds of up to 100km/h (60mph).
The cyclone killed more than 10 people, including crew members of an oil tanker which ran ground near Chennai (Madras).
Heavy rains have disrupted normal life, as well as rail and road traffic in at least six districts in coastal areas of Andhra Pradesh. Crops have also been damaged.
The districts of Visakhapatnam, East and West Godavari, Krishna, Guntur and Khammam are among the worst hit by the flooding.
Most of the deaths were caused by drowning and house collapses in East Godavari district, which experienced the heaviest rainfall in 40 years, senior official T Radha told the Associated Press news agency.
Mr Radha said 95,000 people had been moved to over 100 state-run relief camps in three districts.
PM Manmohan Singh had called state Chief Minister Kiran Kumar Reddy and offered federal help for the flood-affected areas, a statement issued by Mr Singh's office said.
