Mumbai: Incessant rain with intermittent moderate to heavy rain since Friday morning has slowed down public transport services and traffic in Mumbai.

Many parts of the country's financial capital received more than 15 mm of rain between 7 am and 8 am. Due to heavy rains, low-lying areas like Sion were waterlogged, forcing authorities to divert road traffic.

Andheri subway between Andheri and Jogeshwari railway stations in the western suburbs was also flooded.

India Meteorological Department (IMD) Mumbai issued a "Nowcast" warning at 8 am, predicting heavy rainfall at isolated places over Mumbai districts during the next 3-4 hours.

The meteorologist has predicted "moderate to heavy rainfall over the city and suburbs" with "very heavy rainfall at isolated places" during the next 24 hours for the Maharashtra capital.

A civic official said a high tide of 3.87 meters would be observed in the Arabian Sea at 4.09 pm. Being a saucer-shaped city, high tide accompanied by heavy rains can cause flooding as water is not released into the sea at that time.

In the 24 hours ending 8 am on Friday, the island city of Mumbai recorded an average of 93.16 mm rainfall. A civic official said the figures for East Mumbai and West Mumbai were 66.03 mm and 78.93 mm respectively.

A spokesperson of Brihanmumbai Electric Supply and Transport (BEST) said the public bus service body has diverted three bus routes due to waterlogging in Sion since 7.50am.

Western Railways and Central Railways, which operate local trains in Mumbai, claimed to the Express that their suburban services were "running". However, passengers complained of some delays, although there was no waterlogging on the tracks.
