The death toll from western India's worst flooding in nearly a century rose to nearly 850 Saturday, officials said, as rescue workers pulled more bodies from landslides triggered by heavy monsoon rains.

Authorities prepared for further floods as the weather office forecast more rain in the next two days in the state of Maharashtra and its capital Bombay, on India's western coast.

The city, India's financial hub, came to a near halt earlier in the week after two days of downpours. "The situation is improving in Bombay. But increased rainfall activity from this morning is worrying us," a relief official said.

Rescue workers continued searching for more bodies believed to be trapped under a huge mound of mud and rocks that had flattened dozens of shanties on hillsides in Bombay's northern suburb of Andheri.

Authorities have already pulled out 70 bodies, raising the city's death toll to 405, and Maharashtra relief secretary Krishna Vatsa said there could be still more bodies under the debris.

Rescuers retrieved 80 bodies from a landslide four days ago in a village about 95 miles south of Bombay and were preparing to begin searching in other places.

"There are at least four landslide sites in the Konkan region where rescue teams have not yet begun to search. So, the death toll could still climb," Vatsa said.

Flights out of Bombay airport, India's busiest, were suspended briefly after an Air India Boeing 747 landing on a flight from the city of Bangalore skidded off a wet runway, officials said. None of the 333 passengers on board was hurt.

"The runway has been cleared again for operations. We hope to clear the backlog of flights by evening," Bombay airport director Sudhir Kumar said.

Train and bus services in Bombay, a city of 16 million, have resumed partial operation, but on Saturday some flood-hit areas remained without running water, electricity or telecommunications links after four days.

Authorities and health workers continued to clear garbage and animal carcasses and sprayed insecticide to prevent the breeding of mosquitoes in stagnant floodwaters. "Efforts to distribute medicines to prevent an epidemic outbreak is underway on a war footing," Vatsa said.

Every year, monsoons flood huge swathes of land in the densely populated nation, which has hundreds of rivers, and causes hundreds of deaths.

People wade through floodwater Saturday in Dudhgaon, 354 miles from Bombay, in what may be India's worst flooding in nearly 100 years.
