Multiple weather systems are responsible for heavy downpour over Mumbai and suburbs. A cyclonic circulation is persisting over the North coast of Maharashtra, the east-west shear zone is also running in the close proximity of Mumbai. The low pressure area over East Madhya Pradesh has a pull effect on monsoon surge over the west coast.

Rain activities over Mumbai and suburbs will continue until tonight but there will be short break in between which will allow the water to flow away. We do not expect the repeat of last night.
Mumbaikars should not lower their guard, as heavy spells are anticipated during the afternoon, evening, and night hours. Rain activities over Mumbai and suburbs will subside by tomorrow, as the rain activities will shift to the north. Therefore, the next 24 hours are crucial. Mumbaikars are advised to remain indoors until tomorrow morning, to avoid traffic jam and waterlogging.
