Tuesday's 316 mm rainfall revived memories of the 2005 floods that killed more than 500 people, the majority of them in shanty slums where more than half the city's population resides. The disaster management team and Brihanmumbai Municipal Corporation (BMC) are on alert that any time people may need them for help. Around 6.30 a.m. the rains triggered a landslide in adjoining Thane district, leading to derailment of 10 coaches of the Nagpur-Mumbai Duronto Express but there were no casualties.
The state government has declared a holiday for all schools and colleges in Mumbai on Wednesday and advised people to step out only if absolutely necessary.
The metropolis received torrential rains the entire day and the India Meteorological Department (IMD) has warned of heavy showers on Wednesday as well. The Navy, which has kept divers and choppers on standby to rescue people, said it was also arranging shelters for stuck in areas like Colaba, Worli and Ghatkopar.
Suburban train services on the Central Railway (CR) mainline resumed this morning after remaining suspended for almost 20 hours due to heavy downpour.
No substantial rainfall has been reported from any part of the city or outskirts and the morning was bright and skies looked less cloudy.
"Evacuation of all stranded passengers is priority and trains will be run throughout the night, if required", it said. He further added that Mumbai is not going to see rains for few hours as the monsoon clouds have moved towards north.
"I could not find any mode of transport and spent my night on the streets instead of trying to reach home", said 62-year-old Gangadin Gupta.
Owing to the inundation of tracks at many places, including flood-prone areas of Sion, Wadala and Bhandup, the Central Railway mainline was completely suspended for more than four hours, while the operations on the harbour line remained suspended all through the day.
But Mumbai already has had about 2,000 mm of rainfall this monsoon season (since June) which is more than normal. The city's famous "dabbawalas" who deliver lunch boxes to more than 200,000 office-goers had to cancel their deliveries. As it is predicted that the rain may vary from "heavy to very heavy rainfall".
