Some schools have advised students to stay at home in view of the high tide, but there has been no official announcement of closure by the government.
However, for many Mumbaikars, the tides offered a rare view of a natural phenomenon after clouds obscured the solar eclipse Wednesday.
Thousands of people excitedly saw the tides from a safe distance at places like Colaba, Marine Drive, Girgaum Chowpatty, Worli Sea-Face, Bandra Bandstand, Juhu Beach, Gorai Beach and Marve Beach yesterday. Today, greater numbers are expected.
Crowds had assembled even at the Thane Creek and commuters were seen craning their necks to see the swirling waters as the trains crossed the railway bridges at Bhayander Creek.
Last week, the MCGM had inserted big and small advertisements in newspapers, warning people of the potential damage that could be wreaked by the high tides and contact details for emergency services.
As many as 11 hotlines have been established and 34 rain gauges have been installed from where round-the-clock information is being collected. Control rooms have been set up at all the 24 civic wards.
Officials said that MCGM would also monitor the situation in flood-prone areas through CCTVs.
