NEW DELHI -- A massive cyclone came ashore along the eastern coast of India about 9 p.m. Saturday, flooding homes throughout the region and leading to the evacuations of more than 800,000 people, one of the largest such evacuations in India's history.
The storm's maximum sustained winds were about 124 miles per hour with gusts reaching 150 m.p.h., according to Indian officials. At least five people were killed in the coastal city of Gopalpur because of heavy rain and high winds before the storm made landfall, officials said. The storm was expected to drop up to 10 inches of rain over the next two days in some areas.
The Indian predictions before the storm made landfall were less alarming than those from meteorological authorities in the United States. Late Friday, the United States Navy's Joint Typhoon Warning Center said the storm, then barreling across the Bay of Bengal, had maximum sustained winds of 161 m.p.h., with gusts reaching 196 m.p.h. -- making it similar to a Category 5 hurricane, the most severe.
But once the storm arrived on land, its intensity was more modest, and Indian officials defended their more measured forecast as having been more accurate.
"We are not trying to downplay the intensity of the cyclone," M. Shashidhar Reddy, vice chairman of the National Disaster Management Authority, said at a news conference Saturday. "In fact, U.S. authorities are overplaying it."
On Saturday, the Joint Typhoon Warning Center, in Hawaii, reduced its estimates, saying they showed maximum sustained winds of about 138 m.p.h. and gusts of up to 167 m.p.h.
L. S. Rathore, director general of the India Meteorological Department, termed the storm, named Cyclone Phailin, a "very serious cyclonic storm." By Sunday, Mr. Reddy said, the storm is likely to be downgraded to a "serious cyclonic storm."
Still, the true scope of natural disasters in India is often not known for days, given its large population and fairly weak central government.
Prime Minister Manmohan Singh said in a statement Saturday that he had been briefed on preparations for the storm and had directed that the central government extend all needed assistance to state officials.
In the Srikakulam district of Andhra Pradesh State, many mud homes and farms were destroyed, and uprooted trees blocked roads, according to officials there. About 30,000 people were evacuated from coastal villages in Andhra Pradesh.
K. Baliah, a district official involved in rescue efforts, said coastal residents were reluctant to leave until they saw sea levels rise. "At first they refused to leave their properties," he said. Then, "when the water started to enter their communities around 2 p.m., the people decided themselves that they must leave."
The surge accompanying the storm is expected to reach nearly 10 feet, weather officials said, which would cause heavy flooding across Andhra Pradesh and Odisha, another coastal state.
A. K. Antony, India's defense minister, said service members from the country's army, air force and navy had been deployed to help in rescue and relief operations.
He said the air force had deployed C-130 aircraft, recently purchased from the United States, to help in the efforts, and the Navy had multiple diving teams with inflatable rafts deployed at important locations. Military helicopters are also available for rescues, he said.
Pentayya Chintakayala, 33, a fisherman from a village near the port city of Visakhapatnam in Andhra Pradesh, said the fishermen of his village had stopped fishing and moved their boats inland, but they were concerned that they could lose everything if the storm was as severe as predicted.
"What they tell us on television and what we see in the waves have nothing to do with each other," he said. "Fishermen don't always listen to the warnings, and 90 percent of the time that's O.K., but 10 percent of the time the warnings are true, and we lose everything because we don't believe them. Fishermen are stubborn like that."
Mr. Chintakayala added that it was difficult to store fishing equipment very far inland, "because the boats are heavy and there isn't much place to store them."
Officials in the Visakhapatnam district were able to evacuate 21,500 people to relief camps by Saturday evening, including 3,500 inhabitants of flood-prone slums in the city of Visakhapatnam. But they said that they had often resorted to force, and that 30,000 more might have to be evacuated if the worst predictions come to pass.
"Basically the people are not willing to come to the shelters, because they are worried that they will lose their belongings," said M. Venkateswarao, the district revenue officer. "They say that nothing bad will happen and that we are unnecessarily forcing them. But even if one person dies, it will look very bad for the district administration."
