Around 250 residents of a slum-dominated area in Mumbai's Kurla were evacuated on Friday morning as Mithi river swelled up following heavy rains in the city and its suburbs, which also affected the local train services, officials said.
However, as water level of the river later subsided, these people returned to their places, they said.
"People residing in Kranti Nagar, a slum-dominated area in Kurla west, located along the bank of Mithi river, were shifted to nearby municipal schools after its water level touched 3.7 metres in the morning with its danger mark being 4 metres," an official of the Brihanmumbai Municipal Corporation (BMC) said.
Mithi river originates from Sanjay Gandhi National Park (SGNP) in Borivali and meets the Arabian sea at Mahim creek. During the 2005 Mumbai flooding, areas around Mithi river were the most affected and Army had to be called in to rescue and shift locals. Hundreds of people had died in the floods that year.
The official said that after the rains took a break following the evacuation of people, Mithi river's water level went down to two metres from 3.7 metres. After that, most of the evacuated people returned to their places.
Heavy rain pounded Mumbai, especially its suburbs, since early morning, the BMC officials said, adding that Mumbai island city recorded 55.3 mm rain, while 135 mm and 140.5 mm rain in Eastern and Western suburbs, respectively between 4 am to 9 am.
A civic official said that the H-East administrative ward of the BMC, which includes areas like Bandra east and Khar east, recorded the highest rainfall of 186.9 mm, followed by 175.5 mm rain in M-west ward that includes Shivaji Nagar, Govandi and Mankhurd areas during those five hours.
Due to the downpour, several low-lying areas in the eastern and western suburbs witnessed water-logging, which led to traffic snarls on the arterial roads.
As a result of water-logging, mainly between Sion and Vidya Vihar section on the Central Railway's main line, and Chunabhatti-Tikal Nagar section on the Harbour line, the suburban train services were badly affected.
A Central Railway spokesperson said the suburban services on both these lines were hit due to water-logging and it led to bunching of trains.
"Due to this, suburban services ran behind schedule and the operations of some long distance trains were also hit," he said.
Meanwhile, the IMD has predicted moderate rain in the city and suburbs with possibility of heavy rainfall at isolated places, the civic official said , adding that the city will witness hightide of 4.08 metres on Friday at 4.26 metres.
Tulsi lake, one of the seven reservoirs that supply drinking water to the metropolis, overflowed due to heavy rains, they said.
