(CNN) -- Hurricane Florence has made landfall in North Carolina, but its crawling pace and overwhelming storm surges are setting up hours and hours of destruction and human suffering -- with dozens desperately awaiting rescue in one flooded city alone.
Florence's center may linger for another whole day along coastal North and South Carolina -- punishing homes with crushing winds and floods and endangering those who've stayed behind.
In the besieged North Carolina city of New Bern, rescuers by midmorning Friday had plucked more than 200 people from rising waters, but about 150 more had to wait as conditions worsened and a storm surge reached 10 feet, officials said.
"In a matter of seconds, my house was flooded up to the waist, and now it is to the chest," said Peggy Perry, who along with three relatives, was trapped early Friday in her New Bern home. "We are stuck in the attic."
Officials urged residents there to take shelter at the highest points of their homes, including rooftops.
Florence's rain will reach 40 inches in some parts of the Carolinas, and gusty winds will send the ocean and rivers spilling into neighborhoods, forecasters said.
By Friday morning, Florence already had:
• Sapped power to more than 384,000 customers in North and South Carolina, emergency officials said.
• Pushed in a storm surge of 10 feet above normal levels in Morehead City, North Carolina, the National Weather Service said.
• Forced more than 60 people to evacuate a hotel in Jacksonville, North Carolina, after part of the roof collapsed, city officials said.
• Canceled more than 1,300 flights along the East Coast through Friday.
Hours earlier, streets along the coast had been transformed into raging streams, and massive waves surged along the Outer Banks.
"There's already water (in the) bottom part of people's houses," Todd Willis, who lives in Kennel Beach, North Carolina, said Thursday night. "This is just the beginning."
• Prolonged, dangerous winds: Hurricane-force winds extend 80 miles from Florence's center. The storm is expected to crawl into far southeastern North Carolina and eastern South Carolina through Saturday, punishing the area over and over with rain and damaging winds.
• Flooding for miles: Up to 40 inches of rain, and storm surges pushing water inland and not allowing rivers to drain, will produce catastrophic flash flooding and prolonged significant river flooding," the National Hurricane Center says. "You're going to have flooding miles and miles inland," the center's director, Ken Graham, said Friday morning.
• Areas threatened: Hurricane and storm surge warnings are in effect for South Santee River in South Carolina to Duck, North Carolina, and the Albemarle and Pamlico sounds.
• Location of Florence: By 8 a.m. Friday, the hurricane was about 10 miles south of Wilmington and was crawling at 6 mph with maximum sustained winds of 90 mph.
• Record gusts: Wilmington's airport recorded a 92-mph wind gust Friday morning -- the fastest measured since Hurricane Donna hit the city in 1960, the NHC said.
• Thanks from Trump: President Trump tweeted his thanks to first responders Friday morning. "Incredible job being done by FEMA, First Responders, Law Enforcement and all. Thank you!" he tweeted.
Rescues and narrow escapes
More than 1 million people had been ordered to evacuate before the streets became inundated.
Florence's circulation was pushing water ashore, especially north of its eye, in coastal or riverside towns like New Bern and Belhaven, turning land to lakes.
In Belhaven, the Pungo River roared into town, crashing up against homes at a waist-high level and higher late Thursday and early Friday, video from Amy Johnson showed.
Morehead City resident Rebecca Marson decided not to evacuate because her surgeon husband wanted to remain behind with other first responders. They're riding out the storm at their home with four children -- ages 11 to 17 -- Marson's friend, four dogs, two chinchillas, a cat and a lizard.
Marson said they'd lost power and the winds were howling outside, but they had enough food and water to last them for days.
New Bern's WCTI television employees fled their studio Thursday night due to rising flood waters. Footage posted on social media showed a meteorologist saying on air that they had to evacuate. He then leaves the studio and leaves a radar of Florence's rain bands playing on a loop.
In Jacksonville, North Carolina, city officials posted photos of toppled gas pumps and a downed trees early Friday, warning residents to take shelter and avoid roadways.
Officials in several states have declared states of emergency, including in the Carolinas, Georgia, Virginia and Maryland, where coastal areas are still recovering from summer storms.
Florence is one of four named storms in the Atlantic.
