Remote villages, including tribal hamlets, in the two Godavari districts remained cut off from rest of the state. Without food and drinking water for the last couple of days, people were still waiting for relief to reach them.
Officials said they were making efforts to provide relief to the marooned villages in the worst-hit districts.
With water levels receding in the swollen rivulets, overflowing reservoirs and tanks, the extent of devastation is becoming evident.
Chief Minister N. Kiran Kumar Reddy on Tuesday visited flood-hit areas in Krishna, Khammam and West Godavari districts. He assured the victims all help, especially to farmers whose standing crops have been destroyed.
The chief minister said he would apprise the central government of the massive damage caused by the rains triggered by Cyclone 'Nilam' and seek financial assistance for the state.
The heavy rains for nearly a week claimed 25 lives and rendered thousands of people homeless. Villages and towns in eight districts were inundated. About 70,000 people were sheltered in relief camps. The floods damaged crops over five lakh hectares, roads and railway tracks.
Several colonies in Vijayawada city in Krishna district remained under water. A similar situation is prevailing in Kakinada town of East Godavari district.
In East and West Godavari districts, famous as the rice bowl of the state, standing paddy and cotton crops over seven lakh acres were damaged.
Officials said the exact extent of damage would be known only after a detailed enumeration at the field level.
Leader of Opposition in the state assembly and Telugu Desam Party (TDP) chief N. Chandrababu Naidu demanded that the destruction caused by the cyclone be declared a national disaster. He said the government failed to take timely action to prevent losses.
