- Falling trees, rough surf blamed for deaths
- Storm makes second landfall in New Jersey
- Power failures leave 2 million in dark
- Tornado reported in Md., Va., and Del.

- About 2.5 million ordered to evacuate along East Coast.
Barely a hurricane Sunday but massive and packed with rain, Irene flooded towns, killed 10 people and knocked out power to more than 2 million homes and businesses as it plodded up the East Coast, saving the strongest winds it had left for New York.
The storm made a second landfall near Little Egg Inlet, New Jersey, at around 5:30 a.m. Sunday, with winds an estimated at 75 mph.
All told, about 2.5 million people have been ordered to leave up and down the East Coast. Irene had an enormous wingspan — 500 miles wide — and threatened 65 million people in the region, estimated at largest number of Americans ever affected by a single storm.
The streets of the nation's largest city were eerily quiet Sunday morning, its transit system shut down because of weather for the first time in history. Mayor Michael Bloomberg warned late Saturday that no matter whether residents of low-lying areas heeded his calls to evacuate, "The time for evacuation is over. Everyone should now go inside and stay inside."
The storm hugged the U.S. coastline on a path that could scrape every state along the coast. By Sunday morning, it had sustained winds of 75 mph, down from 100 mph on Friday. That made it a Category 1, the least threatening on a 1-to-5 scale, and barely stronger than a tropical storm. Nevertheless, it was still considered highly dangerous, capable of causing ruinous flooding with a combination of storm surge, high tides and 6 to 12 inches of rain.Video: Flooding damages historic boardwalk (on this page)
Tornadoes were reported in Maryland and Delaware, and several warnings were issued elsewhere, including New York and Philadelphia.
Irene caused flooding from North Carolina to Delaware, both from the seven-foot waves it pushed into the coast and from heavy rain. Eastern North Carolina got 10 to 14 inches of rain, according to the National Weather Service. Virginia's Hampton Roads area was drenched with at least nine inches, with 16 reported in some spots.
More than 1 million homes and businesses lost power in Virginia alone, where three people were killed by falling trees, at least one tornado touched down and about 100 roads were closed. Emergency crews around the region prepared to head out at daybreak to assess the damage, though with some roads impassable and rivers still rising, it could take days.

Some held out optimism that their communities had suffered less damage than they had feared.
"I think it's a little strong to say we dodged a bullet. However, it certainly could have turned out worse for the Hampton Roads area [of Virginia]," said National Weather Service meteorologist Mike Montefusco.
Officials warned residents to remain inside.
"Everything is still in effect," National Hurricane Center spokesman Dennis Feltgen said. "The last thing people should do is go outside. They need to get inside and stay in a safe place until this thing is over."

Ed Rappaport, deputy director of the National Hurricane Center in Florida, said the storm is so large that areas far from Irene's center are going to be feeling strong winds and getting large amounts of rain, he said.
"It is a big, windy, rainy event," he said.Video: Social media key to storm communications (on this page)
Irene was the first hurricane to make landfall in the continental United States since 2008, and came almost six years to the day after Katrina ravaged New Orleans on Aug. 29, 2005. Experts said that probably no other hurricane in American history had threatened as many people.
Airlines said 9,000 flights were canceled, including 3,000 on Saturday. The number of passengers affected could easily be millions because so many flights make connections on the East Coast.
Greyhound suspended bus service between Richmond, Va., and Boston. Amtrak canceled trains in the Northeast for Sunday.
Storm wields death
Storm-toppled trees, roiled surf and other effects left left at least 10 people dead by Saturday night as Irene passed, according to local officials.
In Virginia, falling trees were blamed for the deaths of a man in his 60s at his Chesterfield County house, a car passenger in Brunswick County, and a boy in a Newport News apartment. A falling tree in Maryland killed one person in a Queen Anne's County house.
In North Carolina, a girl died in a wreck after the car she was in crashed at an intersection where Irene had knocked out power to the traffic lights. One person died in a vehicle crash in Pitt County; a man died after a branch fell on him in Nash County; and a man died of a heart attack in Onslow County as he was boarding up his home.

Irene's impact varied by region and state.

In New York, authorities undertook the herculean job of bringing the city to a halt. The Metropolitan Transportation Authority shut down its subways, trains and buses for a natural disaster for the first time, a job that began at noon Saturday and took into late that night to complete.
On Wall Street, sandbags were placed around subway grates near the East River because of fear of flooding. Tarps were spread over other grates. Construction stopped throughout the city, and workers at the site of the World Trade Center dismantled a crane and secured equipment.PhotoBlog: Eye of the storm

She said she planned to remain in the row house along with her daughter and adult grandson, although with a wary eye on the park across the street that routinely floods during heavy rains.
"I'm not a fool; if it starts coming up from the park, I'm leaving," she said. "It's the wind I'm more concerned about than anything."
