Three people, including two children, were killed when a house collapsed in Mumbai in the heavy rain last night, news agency PTI said. In neighbouring Thane, a 32-year-old woman and a teenage girl died and two others were injured in rain-related incidents.

Local train services, paralysed yesterday because tracks were flooded, resumed last last night on most lines with water receding. Trains ran all through the night to ferry home people stranded for hours at stations and offices on Tuesday.

Flight operations are normal this morning at Mumbai airport, the airport offiial said. Poor visibility forced diversion and delay of at least 10 flights on Tuesday.

Five teams of the National Disaster Response Force (NDRF) have been deployed to rescue people. The Navy has divers and choppers on standby and its cadets ran food camps and arranged shelter for people stuck in areas like Colaba, Worli and Ghatkopar.

There are fewer people on Mumbai's roads this morning with schools and colleges closed and many staying home. Thousands emerge from train stations to head to their offices every morning in the heart of Mumbai, but today there were people going into the stations to return home after a night out in the city.

Six long distance trains between Mumbai and Delhi, Valsad and Punjab have been cancelled.

Mumbai's famous dabbawalas, who deliver tiffins to offices, won't operate today as they were not able to "collect the lunch boxes which they delivered yesterday," said their spokesperson.

The rain on Tuesday, 30 times the average, had brought Mumbai to standstill on Tuesday with water flooding low lying areas. Thousands waded through waist-deep water, abandoning cars to walk. There were massive traffic jams that cleared only by late in the night. Traffic on the Bandra-Worli Sea Link was stopped for several hours to clear traffic gridlocks.

Power outages were reported in several parts of the city.
