The first warning signal has been raised as floods in river Krishna crossed the four lakh cusecs mark at Prakasam Barrage in Vijayawada on Friday.
In river Godavari at Sir Arthur Cotton Barrage in Dowaleswaram near Rajamahendravaram, the flood flow remained steady at 14.76 lakh cusecs (cubic foot of water flow per second), going past the second danger level.
According to the Andhra Pradesh State Disaster Management Authority, the flood level showed a marginal decrease at upstream Bhadrachalam in Telangana on Friday afternoon, with signs of a further decline over the next few hours.
SDMA Managing Director B R Ambedkar said people along the Krishna riverbanks should remain on alert as the flood level might increase.

Three teams each of the National Disaster Response Force (NDRF) and the SDRF have been carrying out rescue and relief operations in Alluri Sitarama Raju, Eluru and B R Ambedkar Konaseema districts.
Ambedkar appealed to people in the deluge-hit habitations in Godavari region to cooperate with the authorities and move to safer places as the second warning has been continuing.
