WILMINGTON, N.C. -- The outer bands of wind and rain from a weakened but still lethal Hurricane Florence began lashing North Carolina on Thursday as the monster storm moved in for a prolonged and potentially catastrophic stay along the Southeast coast that could drench the homes of as many as 10 million people.
Florence's winds dropped from a peak of 140 mph to 110 mph early Thursday .
That reduced Florence from a Category 4 hurricane to a Category 2, but forecasters warned that the widening storm — and its likelihood of lingering around the coast day after day after day — will bring ocean water surging onto land and torrential rain.
"It truly is really about the whole size of this storm," National Hurricane Center Director Ken Graham said. "The larger and the slower the storm is, the greater the threat and the impact — and we have that."
As of 11 a.m. EDT, the Category 2 storm was centered about 145 miles east-southeast of Wilmington, North Carolina, and about 195 miles east of Myrtle Beach, South Carolina.
Its forward movement slowed to 10 mph and top sustained winds dropped slightly to 105 mph.
Forecasters said Florence's eye could come ashore early Friday around the North Carolina-South Carolina line.
Then it is likely to hover along the coast Saturday, pushing up to 13 feet of storm surge and unloading water on both states.
The forecast calls for as much as 40 inches of rain over seven days along the coast, with the deluge continuing even as the center of the storm pushes its way over the Appalachian Mountains.
The result: Catastrophic inland flooding that could swamp homes, businesses, farm fields and industrial sites.
The police chief of a barrier island in Florence's bulls'-eye said he was seeking next-of-kin contact information from the few residents who refused to evacuate.
"I'm not going to put our personnel in harm's way, especially for people that we've already told to evacuate," Wrightsville Beach Police Chief Dan House said.
North Carolina Gov. Roy Cooper urged residents to remain alert despite changing forecasts.
"Don't relax, don't get complacent. Stay on guard. This is a powerful storm that can kill. Today the threat becomes a reality," he said.
About 5.25 million people live in areas under hurricane warnings or watches, and 4.9 million in places covered by tropical storm warnings or watches, the National Weather Service said.
Weather Underground meteorology director Jeff Masters said Florence eventually could strike as a Category 1 with winds less than 100 mph, but that's still enough to cause at least $1 billion in damage.
Water kills more people in hurricanes than wind does.
It's unclear exactly how many people fled, but more than 1.7 million people in the Carolinas and Virginia were warned to clear out.
Airlines canceled nearly 1,000 flights and counting.
Home Depot and Lowe's activated emergency response centers to get generators, trash bags and bottled water to stores before and after the storm. The two hardware chains said they sent in a total of around 1,100 trucks.
Duke Energy, the nation's No. 2 power company, said Florence could knock out electricity to three-quarters of its 4 million customers in the Carolinas, and outages could last for weeks.
Workers are being brought in from the Midwest and Florida to help in the storm's aftermath, it said.
Florence's weakening as it neared the coast created tension between some who left home and authorities who worried that the storm could still be deadly.
Frustrated after evacuating his beach home for a storm that has since been downgraded, retired nurse Frederick Fisher grumbled in the lobby of a hotel in Wilmington several miles inland.
"Against my better judgment, due to emotionalism, I evacuated," he said. "I've got four cats inside the house. If I can't get back in a week, after a while they might turn on each other or trash the place."AlertMe
