Heavy rains in Mumbai and neighbouring areas brought life to a halt, disrupting rail and road traffic on Tuesday. State minister Aaditya Thackeray, who visited several areas in the city, said this is probably the heaviest rainfall Mumbai has seen in a '12-hour span' since July 2005. Several areas in the city and suburbs received more than 200 mm rainfall since Monday night and heavy showers were predicted for the next 48 hours. The city's civic body appealed to residents to stay at home. A 35-year-old woman and her three children were swept away in a swollen nullah after their house collapsed due to heavy rainfall in Santacruz. While police managed to save one of the children, the NDRF has recovered 2 bodies from site.
