Mumbai and its surrounding areas received extremely heavy rainfall throughout the night on Monday and it continued on Tuesday, leading to flooding in many areas and traffic disruption across the city.

Mumbai recorded 230 mm rainfall within 10 hours. BMC commissioner Iqbal Singh Chahal said over 163 pumps were being used to ease the inundation in different parts of the city. The incessant rainfall threw normal life out of gear in Mumbai, Thane, Palghar, and Raigad (MMR areas).

In an untoward incident, a 15-year-old boy Rakib A. Mandal was electrocuted when he came in contact with a live wire of a street-light pole near the Owala Hanuman Temple on Ghodbunder Road in Thane.

The heavy rainfall caused a massive landslide on the Western Express Highway between Kandivli and Malad, affecting south-bound traffic. No casualties were reported. The civic body deployed six JCBs to clear debris, stones and open the highway for vehicular movement.

The intense rains caused major traffic jams. The BEST diverted its routes in Dadar, King Circle, Parel, Wadala, Chembur, Kurla, Sion, and Bandra due to waterlogging in these areas.

The extremely heavy rains brought Mumbai's lifeline - the local train services - to a halt. Services on all three lines were suspended partially between Churchgate and Andheri on Western Railway, between Thane-Mumbai CSMT on the mainline and Kurla-CSMT on the harbour line.

Western Railway's chief public relations officer Sumit Thakur said that suburban services have been suspended between Andheri to Churchgate, but are running between Andheri to Virar and beyond on WR.

With the heavy rains bringing Mumbai and its adjoining areas to a standstill, the Maharashtra government declared a holiday in the city and Mumbai Metropolitan Region areas.

Several houses, shops, and residential areas were flooded in slums or low-lying areas in Malad, Kurla, Ghatkopar, Parel with people struggling to save their valuables from getting wet.

BMC Commissioner Iqbal Singh Chahal and state cabinet minister Aaditya Thackeray along with top civic officials visited areas where flooding was reported to supervise the relief operations being undertaken. Mumbai Mayor Kishori Pednekar also visited the BKC pumping station to take stock of the situation.

The India Meteorological Department (IMD) has predicted heavy to very heavy rainfall in the city and surroundings over the next 24 hours. The weather agency also forecasted high-tides and another swell after midnight.

Taking to Twitter, the BMC urged Mumbaikars to not venture out unless extremely necessary and advised the citizens to stay away from the shore and waterlogged areas. Meanwhile, all offices and establishments in Mumbai, except emergency services, have been asked to remain shut.

Private weather agency Skymet said that the ongoing heavy rains are likely to continue in Mumbai and neighbouring areas till August 5. It further said that rain activities in Mumbai will see a drop from August 6 after which the city is likely to continue witnessing moderate showers with isolated intense spells at regular intervals.

The MeT department has issued a 'Red' alert for Mumbai, Thane, Raigad, and Palghar for the next 48 hours.
