July 1 (Bloomberg) -- Train services and road traffic were disrupted in India's commercial capital of Mumbai as heavy overnight rains flooded streets and railway tracks.

Two of the three suburban train networks were shut by the 8 a.m. rush hour, according to the city's police control room. Trains in the third network were running about 25 minutes behind schedule. Several streets across the Manhattan-shaped island city were under water as deep as 1 1/2-feet (46 centimeters).

The main business establishments, including the nation's central bank, the Bombay Stock Exchange and head offices of companies, banks and brokerages are based in the southern end of the city of 17 million people. Trains move about a third of the city's population every day. The city's currency, stock and bond markets were all scheduled to open.

Flights were on schedule although a high tide at 11 a.m. accompanied by rains may make draining of the rain water into the sea difficult, according to the control room. Heavy rains are forecast in the next 24 hours, the city's weather office said.

The heaviest rains in a century in July 2005 killed more than 400 people in Mumbai and shuttered schools, banks and markets. Monsoon rains that run from June to September account for four-fifths of the country's annual rainfall.
