The Municipal Corporation of Greater Mumbai (MCGM) had issued warnings to people in low lying and coastal areas to watch out for the gigantic tides and take adequate precautions.

On Wednesday, the city witnessed a 4.85-metre high tide that flooded slums at Cuffe Parade and Vile Parle.

The fire brigade had responded to distress calls and rescued 23 people from the affected areas.

In a precautionary measure, the MCGM last week inserted big and small advertisements in the Mumbai newspapers warning people of the potential damage by the high tides and details of emergency services contact numbers.

Civic officials said that MCGM would also monitor the situation in flood-prone areas through closed circuit TVs.

As many as 11 hotlines have been established and 34 rain gauges are installed from where round the clock information on rainfall is being collected, and control rooms have been set up at all 24 civic wards, a civic official said.
