The "extremely unsafe major hurricane" is predicted to hit the coast late Thursday or early Friday morning, dropping as much as 30 inches of rain in some areas and wind gusts in the 140 miles per hour range, says the National Hurricane Center.
Maximum sustained winds were clocked at 140 miles per hour (220 kph) as it moved west-northwest at 13 miles per hour (20 kph).
If the hurricane makes landfall, this so-called brick wall will likely play the villain again; the brick wall is expected to weaken, meaning it won't help steer Florence out to sea.
Meanwhile, Hurricane Florence was 580 miles south, south east of Bermuda with winds of 115 mph and strengthening into a major storm. "We are expecting more wind than we had with Hugo and more water than we had with Matthew".
"The bottom line is that there is high confidence that Florence will be a large and extremely unsafe hurricane, regardless of its exact intensity", the hurricane center said.
The latest projections from the hurricane center show the "cone of uncertainty" extending from roughly Georgetown, S.C., to Cape Lookout.
Most manure pits could handle up to 25 inches of rain, Curliss said.
This satellite image offers a sobering look at the category 4 storm as it barrels toward the Carolina coast, with Myrtle Beach and Wilmington expected to take a direct hit from the storm.
Although as of yesterday afternoon Hurricane Florence was a Category 3 hurricane, models and forecasts predict that it will intensify into a Category 4 hurricane.
A warm ocean gives hurricanes their fuel, and Florence is moving over an area with water temperatures nearing 85 degrees (30 Celsius), hurricane specialist Eric Blake wrote.
At this height of the Atlantic hurricane season, Florence was being trailed on east-to-west paths by two other storms, Helene and Isaac.
Major storms and flooding hit the Carolinas in 2015 and 2016.
Large cities and towns that lie within the most threatened zone include Jacksonville, Greenville, New Bern, Morehead City and Kinston, says the center.
The winds will be strong enough to knock down trees, damage structures and cause widespread power outages, the center warned.
"After it comes inland, it's not going to move hardly at all for three days.When we're talking 30-40 inches of rain, if that occurs over the mountains of NC or VA then you are looking at a catastrophic flooding event", Cash told CBN News. That same block of counties is also facing an elevated tornado threat, according to the National Hurricane Center.
It's expected to be the worst in the region since Hurricane Hazel made landfall near the North Carolina-South Caroline border in 1954.
Flash flooding is expected Thursday into Saturday, while river flooding from heavy rainfall could persist for several days to weeks after the storm.
Evacuations of coastal North Carolina began at noon Monday, with Dare County officials calling for the entire county to evacuate. "If someone is in a low-lying area that is subject to flood, they need to have a plan in place".
Even as the computer models that meteorologists use to derive their forecasts converged on the idea that the hurricane will not make a northward turn away from land before reaching the United States, it became more evident that a growing area of high pressure north of the storm would cause the storm to slow down - perhaps even stalling - once it reaches the coast.
