Mumbai has been brought to a virtual standstill after heavy rain pounded the city through the night, killing 16 people in the city and neighbouring Thane. The local trains, a lifeline for Mumbai's 20 million residents, have been affected badly with many suburban as well as long-distance trains cancelled. After the Maharashtra government declared a public holiday in Mumbai and its suburbs, Chief Minister Devendra Fadnavis advised residents to stay indoors as the weather office has sounded a red alert in Mumbai today, warning of heavy rain. Mumbai's streets regularly flood during the monsoon, which runs from June until September or October, and which provides India with most of its annual rainfall. Mumbai has received 375 millimetres of rain since Monday - the highest over a 24-hour period in a decade.
