The heavy rains and the high tide have overloaded an ageing drainage system, bringing down Mumbai to its knees. The city is once again staring at an imminent flood.
According to the weathermen, this could be the worst rain since July 2005, when the city was devastated by floods.
The Maharashtra government has also ordered offices to allow employees to leave early.
Images shared online by Mumbaikars show cars inundated in rain water and residents struggling to cross roads.
The disaster management team and Brihanmumbai Municipal Corporation (BMC) are on alert and water logging has been reported in several parts of the city. Mumbai Police have also issued an alert stating that heavy water-logging is expected in the next few hours due to heavy showers and high tide.
The Indian Navy has kept five flood rescue teams and two diving teams ready to render assistance at different locations across Mumbai.
