The river Adyar is seen in images flooded almost to the edge of a bridge.
Residents were seen climbing out of their homes or being pulled out to safety in the low-lying parts of Chennai where water is almost neck-deep.
People were seen climbing out of their homes or climbing onto floating barrels.
People are stuck in many areas without food or water.
