Mumbai received the highest rainfall of the season within just 12 hours on Wednesday besides the highest-ever wind speed, the city civic body said.
According to the Brihanmumbai Municipal Corporation (BMC), the island city recorded 215.8 mm rain, followed by 101.9 mm in eastern suburbs and 76.03 mm in western suburbs.
Meanwhile, several roads like Mahapalika Marg and Colaba Causeway Road in south Mumbai were blocked and closed for traffic after trees collapsed due to high-velocity winds in the evening.
According to sources, several roads and areas in south Mumbai, which never witnessed water-logging in the past, were flooded and scores of vehicles, including BEST buses, were stranded on roads.
Many motorists abandoned their vehicles in flooded streets due to breakdown, which badly affected the traffic movements.
Several videos of rain havoc in Mumbai went viral on social media on Wednesday, showing floodwater inside shops, building compounds and slums.
