NAGS HEAD, N.C. — Farmer Wilson Daughtry shrugged off an evacuation order and raced to harvest all the corn and squash he could hours before the initial waves churned up by Hurricane Irene started bumping the outer islands of North Carolina. Far away in Maine, lobsterman Greg Griffin reported his colleagues were stowing traps and tying up boats, heeding forecasts of 30-foot battering waves to come.
For hundreds of miles, as many as 65 million people along the densely populated East Coast warily waited Friday for a dangerous hurricane that has the potential to inflict billions of dollars in damages anywhere within that urban sprawl that arcs from Washington and Baltimore through Philadelphia, New York, Boston and beyond.
The main thrust of Irene wasn't expected in North Carolina until sometime Saturday. But heightened waves from the enormous Category 3 storm weren't waiting, already hitting the Outer Banks early Friday where many tourists and regular islanders had packed up and left, the National Weather Service said.
Buxton, N.C. real estate agent Danny Couch owns a bus tour business on Hatteras Island and worries about Irene's damage potential in unexpected ways. Not the Cape Hatteras Lighthouse or other icons of the Outer Banks, but N.C. Highway 12, the two-lane road that runs up and down the vulnerable barrier island.
That's a lifeline for the community, along with the aged Bonner Bridge, the only connection to the mainland other than two ferries.
"It always the road," he said when asked what he will check when Irene passes. "That's your way in, that's your way out."
North Carolina was just first in line along the Eastern Seaboard — home to some of the nation's most heavily populated areas and some of its priciest real estate. Besides major cities, sprawling suburban bedroom communities, ports, airports, highway networks, cropland and mile after mile of built-up beachfront neighborhoods are in harm's way.
"One of my greatest nightmares was having a major hurricane go up the whole Northeast coast," Max Mayfield, the National Hurricane Center's retired director, told The Associated Press on Thursday as the storm lurched toward the U.S. "This is going to be a real challenge ... There's going to be millions of people affected."
The enormous Category 3 storm with winds of 115 mph (185 kph) — the threshold for a major hurricane — would be the strongest to strike the East Coast in seven years, and people were already getting out of the way. After dousing the Bahamas, it was again moving over warm Atlantic waters that will energize it.
The center of the storm was still about 460 miles (740 kilometers) south-southwest of Cape Hatteras and moving to the north at 14 mph (22 kph).
Hurricane watches already extend all the way to New Jersey and New York was likely next.
Hundreds of thousands of New Yorkers were told Thursday to pack a bag and be prepared to move elsewhere. The nation's biggest city hasn't seen a hurricane in decades.
Farther south, tens of thousands packed up and left North Carolina beach towns and farmers pulled up their crops.
Daughtry has lost count of how many times his crops have been wiped out by storms that regularly blow up from the tropics.
"That's the price of living in paradise," he said of a fertile farm belt that's weathered an unusually hot and dry summer. Any deluge from Irene's rain bands could wipe out many crops just when they are ready for harvesting.
What's at stake in North Carolina? Latest figures show coastal North Carolina's fields earned nearly $6.3 billion in farm income in 2009 alone from its tobacco, corn and other crops.
Risks are many from Irene's wrath: surging seas, drenching rains, flash floods and high winds are all possibilities the Federal Emergency Management Agency director wasn't counting out.
"We're going to have damages, we just don't know how bad," Craig Fugate told AP as FEMA readied plans in many states. "This is one of the largest populations that will be impacted by one storm at one time."
Not just infrastructure, but jobs are also at stake.
Take Mary Thomas of Nags Head, a 34-year-old motel worker.
"We depend on tourism," said Thomas. "If we're hit, the motel will be shut down for a while. Businesses will be closed. People will have to rebuild. And that means I'll be out of a job."
The Outer Banks attracts thousands of tourists each year who stay in hotels and motels or the upscale homes lining the oceanfront. Many workers, like Thomas, earn a living by working in restaurants that cater to the tourists — and some were struggling before the storm barreled toward North Carolina.
"I just don't know what I would do if I lose my job," said Thomas, the mother of two.
Latest forecasts had Irene crashing up the North Carolina coastline Saturday, then churning up the East while drenching areas from Virginia to New York City before a much-weakened storm reaches New England.
Even if the winds aren't strong enough to damage buildings in a metropolis made largely of brick, concrete and steel, a lot of New York's subway system and other infrastructure is underground and subject to flooding in the event of an unusually strong storm surge or heavy rains, authorities noted.
New York City's two airports also are close to the water and could be inundated, as could densely packed neighborhoods, if the storm pushes ocean water into the city's waterways, officials said. The city had a brush with a tropical storm, Hanna, in 2008 that dumped 3 inches of rain in Manhattan.
All told, Irene could cause billions of dollars in damages or more along the Eastern Seaboard in a worst case scenario, said Kathleen Tierney, director of the Natural Hazards Center at the University of Colorado.
In the last 200 years, New York has seen only a few significant hurricanes. In September of 1821, a hurricane raised tides by 13 feet in an hour and flooded all of Manhattan south of Canal Street, the southernmost tip of the city. The area now includes Wall Street and the World Trade Center memorial.
New England is also unaccustomed to direct hits from hurricanes. Griffin, who fishes from Portland, Maine, still recalls the clobbering when Hurricane Gloria struck in 1985 and said this one is not one to ignore after years without a large, dangerous storm.
"We have a young generation of lobstermen who've never experienced a full-blown hurricane," Griffin warned.
The first U.S. injuries from Irene appeared to be in South Florida near West Palm Beach where eight people were washed off a jetty Thursday by a large wave churned up by the storm.
In Washington, Irene dashed hopes of dedicating a 30-foot sculpture to the late Martin Luther King Jr. on the National Mall on Sunday with the help of President Barack Obama. While a direct strike on the nation's capital appeared slim, organizers said the forecasts of wind and heavy rain made it too dangerous to summon a throng they initially expected to number up to 250,000 strong.
CoreLogic, a company that provides strategic information to businesses and others, issued a statement Thursday that its data showed some 1.8 million residential and commercial properties in the region were at potential risk to storm surge flooding. It said those properties are in 12 major coastal metropolitan areas within Irene's projected path and added Long Island, New York, faced the highest risk with nearly 388,000 properties.
Heavy rain and possible floods were big worries in the Northeast. The potential for flooding and wind damage are Irene's greatest threats to Rhode Island, still smarting from the 2010 spring floods that devastated parts of the Ocean State.
In Connecticut, Gov. Daniel P. Malloy declared a state of emergency and warned there could be prolonged power outages if Irene dumps up to a foot of rain on already saturated ground as some fear. He said emergency responders must be ready in event of any evacuations from heavily developed urban areas.
"We are a much more urban state than we were in 1938," he said, referring to the year that the so-called "Long Island Express" hurricane killed 600 people and caused major damage with 17-foot storm surges and high winds.
The urban population explosion in recent decades also worries New Jersey officials. Gov. Chris Christie encouraged anyone on that state's heavily built-up shoreline to begin preparations to leave.
Hurricanes have made landfall on New Jersey just twice in the last 200 years, in 1821 and 1903, the latter battering the Atlantic City area. But the state now has 8.8 million people and coastal areas packed with homes and businesses — and 11 major casinos in Atlantic City.

The beach community of Ocean City, Md., was taking no chances, ordering thousands of people to leave.
"This is not a time to get out the camera and sit on the beach and take pictures of the waves," said Maryland Gov. Martin O'Malley.
