More than 20 people are reported to have been killed in India's Maharashtra state by floods and landslides caused by heavy monsoon rains.
Some Mumbai residents say the monsoon has never been this heavy
The worst affected area is the Raigad district south of the state capital, Mumbai (Bombay).
The rains have caused chaos in Mumbai where some residents say they have never seen such heavy monsoon falls.
Monsoon floods at the end of June and early July left more than 50 people dead in neighbouring Gujarat state.
A senior official in Raigad district told the BBC that at least 23 have died there.
Sanjay Yadav said 12 people were killed in landslides and 11 others were drowned in rising flood waters.
Mr Yadav said navy divers and helicopters have been deployed for rescue operations.
In Mumbai hundreds of thousands of commuters have been stuck on the roads and in railway trains and stations.
Flights in and out of the city have been cancelled. Trains are at a standstill and some mobile phone networks have been disrupted.
Many Mumbai residents have told the BBC that their homes have been flooded and they need help.
Stranded commuters have been unable to call their families as some mobile phone lines are not working.
Mumbai often suffers monsoon flooding but some residents say they have not seen a problem of this magnitude before, the BBC's Zubair Ahmed in the city says.
