In Wilmington, near where the eye of the storm touched down, trees and power lines were felled and many windows were broken. They have first confirmed fatalities related to the storm, according to the Wilmington Police Department.
"Florence is here to stay for awhile", McMaster said from Columbia Friday afternoon.
A day after blowing ashore with 90 miles per hour (145 kph) winds, Florence practically parked itself over land all day long and poured on the rain. That's enough to fill the Chesapeake Bay or cover the entire state of Texas with almost 4 inches (10 centimeters) of water, he calculated.
The greatest storm surge inundation is expected between Cape Fear and Cape Hatteras, including the Neuse and Pamlico Rivers and western Pamlico Sound, the National Hurricane Center said.
Storm surge: Up to 13 feet, and seawaters could push inland 2 miles, depending on how long Florence lingers. Rescue crews have used boats to reach hundreds besieged by the rising waters.
More than 2 feet (60 centimeters) of rain had fallen in places, and the drenching went on and on, with forecasters saying there could be an additional 1½ feet (45 centimeters) before Sunday is out. To rescue as many animals as possible.

Typhoon Mangkhut slammed into the Philippines, ripping off tin roof sheets and knocking out power in an agricultural region of flood-prone rice plains and landslide-prone mountain provinces. Significant weakening was expected over the weekend. According to Meteorologist Ryan Maue, the 18 trillion gallons are enough to "fill the Chesapeake Bay or cover the entire state of Texas with almost 4 inches (10 centimeters) of water".
Florence is expected to dump 18 trillion gallons of rainwater on United States soil, meteorologist Ryan Maue tweeted. That's still less than the 25 trillion gallons Hurricane Harvey dropped a year ago in Texas and Louisiana. The government's response to Hurricane Florence is seen by many as a test, especially after the criticism that the Federal Emergency Management Agency (FEMA) received for their actions after Hurricane Maria.
"All evacuation orders from local officials should be followed because of this risky threat", the Weather Channel said.
In its initial onslaught along the coast, Florence buckled buildings, deluged entire communities and knocked out power to more than 900,000 homes and businesses.
In North Carolina, hog and poultry waste pits make up 6,848 acres of land according to a report from the Environmental Working Group.
Renato Solidum, Philippine under-secretary for Disaster Risk Reduction and Climate Change Affairs, told CTV News Channel that they need to prepare for the "direct physical impact of the typhoon and also the (resulting) consequences". It caused most of the 1,200 deaths in Hurricane Katrina in 2005.
