Fourteen people have died in the past two days in western Gujarat state alone, taking the toll there to 63, a Press Trust of India (PTI) news agency report said.

PTI said more than 7,000 people had been evacuated from low-lying areas in Gujarat as the rains worsened, and 22 children had to be rescued when their school bus was surrounded by swirling flood waters.

In the eastern state of West Bengal, six members of the same family were killed Tuesday when rain washed away their hut in a village 40km south of state capital Kolkata.

No flights took off from Kolkata Tuesday, a city official said.

"Transport was disrupted as arterial roads in Kolkata remained waterlogged and the underground sewer system failed to drain out the water," said mayor Bikash Ranjan Bhattacharya.

In Maharashtra state, where rains left financial hub Mumbai waterlogged over the weekend and disrupted flights and trains as the city's river overflowed, 19 more deaths have been reported since Sunday.

"The death toll from the state stands at 62," Ramesh Kumar, principal secretary of relief and rehabilitation said on Tuesday.

Fifteen of the deaths were in Mumbai, mainly from electrocution and collapsing walls, said Mumbai's civic chief Jairaj Pathak

Some 5,000 people had been moved from flooded areas on the weekend, but rainfall had eased and the city was back to normal, the state's director of disaster management Suvas C Mohanty said.
