What is Steering Hurricane Florence?
At a Glance
- Florence is a dangerous Category 2 hurricane.
- Florence is expected to crawl near or along the coast of the Carolinas through Friday.
- This will produce catastrophic flash flooding and major river flooding.
- Life-threatening storm surge will occur near landfall and for some time after.
- Hurricane and storm surge warnings have been issued.
- Hurricane-force winds are arriving in eastern North Carolina.
- Florence’s remnant will linger in parts of the East into early next week.
Hurricane Florence is spreading heavy rain and strong winds into the Carolinas, with landfall possible either overnight tonight or on Friday, kicking off an agonizing crawl through the Southeast into early next week, producing catastrophic inland rainfall flooding, life-threatening storm surge and destructive winds.
As of 10 p.m., Florence’s eye was located about 70 miles east-southeast of Wilmington, North Carolina, crawling northwestward at just 5 mph.
Wind gusts have reached as high as 106 mph at Cape Lookout, North Carolina while a 105 mph gust was also reported at Fort Macon, North Carolina recently.
The highest sustained wind so far was reported in Cape Lookout with a sustained wind of 83 mph.
Ten feet of storm surge is flooding Cherry Point in western Pamlico Sound. A gauge at Oriental, North Carolina, on the Neuse River recorded a water height of about six feet above normal tide levels.
Extreme rainfall is already occurring in eastern North Carolina. Atlantic Beach, which is a barrier island just south of Morehead City, has measured 12.73 inches of rainfall through mid-evening.
Increasingly stronger bands of rain and wind are pushing ashore in eastern North Carolina, only the beginning of what could be a record-wet siege from a tropical cyclone in parts of the Tar Heel State.
As you can see, the eye of Florence is now visible from National Weather Service Doppler radar just south of Morehead City.
Hurricane-force winds (74-plus mph) extend outward up to 80 miles from the center, and tropical-storm-force winds (39-plus mph) extend outward up to 195 miles from the center.
Other Wind Reports
Winds are already gusting above 80 mph at times along the North Carolina coast, with winds gusting over 100 mph in a few spots.
Sustained winds of 79 mph (or to hurricane force) are currently occurring in Davis, North Carolina and a 70 mph sustained wind was recorded at Fort Macon, North Carolina.
Water levels continue to rise quickly on the western side of Pamlico Sound in North Carolina, including a six foot storm surge in New Bern.
Significant storm-surge flooding had already inundated New Bern, North Carolina, as of this evening. A storm surge of around 6 feet was reported there by a storm chaser.
There’s continues to be overwash of the dunes at the “S” curves on Highway 12 near Rodanthe in the Outer Banks.
The National Hurricane Center noted late Wednesday that while Florence has weakened some, “the wind field of the hurricane continues to grow in size. This evolution will produce storm surges similar to that of a more intense, but smaller, hurricane, and thus the storm-surge values seen in the previous advisory are still valid.”
Previous large Category 2 hurricanes have done enormous amounts of damage along the U.S. coast.
A hurricane warning and storm surge warning are in effect from the South Santee River, South Carolina, to Duck, North Carolina, including the Albemarle and Pamlico sounds. These warnings include Myrtle Beach, South Carolina, Wilmington, North Carolina, and most of the Outer Banks.
Hurricane warnings also extend inland, including North Carolina cities such as Greenville, Goldsboro and Kinston.
Hurricane watches are in effect from Edisto Beach, South Carolina, northward to the South Santee River, South Carolina. This includes Charleston, South Carolina.
Storm surge watches remain posted north of Duck, North Carolina, to the border between North Carolina and Virginia, as well as from Edisto Beach, South Carolina, northward to the South Santee River, South Carolina.
Tropical storm warnings are in effect north of Duck, North Carolina, to Cape Charles Lighthouse, Virginia, as well as for the Chesapeake Bay south of New Point Comfort, Virginia, and from Edisto Beach, South Carolina, northward to the South Santee River, South Carolina. This includes Virginia Beach, Norfolk, Virginia, and Charleston, South Carolina.
A hurricane warning means hurricane-force winds (74-plus mph) are expected somewhere within the warning area and is typically issued 36 hours ahead of the arrival of tropical-storm-force winds (39-plus mph), which could make last-minute preparations difficult.
A storm surge warning means there is a danger of life-threatening storm-surge inundation within the warning area during the next 36 hours from rising water moving inland from the coastline.
(LATEST NEWS: Power Outages Mounting)
High pressure aloft over the western Atlantic Ocean has weakened, allowing Florence to slow down tremendously as it’s steered toward the coast of the Carolinas.
Little change in strength is expected before Florence eventually reaches the coast overnight tonight or on Friday. Regardless, Florence will remain a dangerous, formidable hurricane as it approaches the coast of the Carolinas into Friday.
– Storm-Surge Impact: A destructive storm surge will accompany the eye coming ashore sometime from tonight into Friday, and coastal flooding may persist through multiple high-tide cycles into this weekend east of the center of Florence. All evacuation orders from local officials should be followed because of this dangerous threat. Significant beach erosion is also likely on the southeastern U.S. coast. Elevated water levels may persist for some time after landfall in areas where onshore winds persist.
Here are the latest storm-surge inundation forecasts from the National Hurricane Center if the eye of Florence arrives at high tide:
– Cape Fear to Cape Lookout, North Carolina, including the Neuse, Pamlico, Pungo and Bay rivers: 7 to 11 feet, with locally higher amounts possible
– Cape Lookout, North Carolina, to Ocracoke Inlet, North Carolina: 6 to 9 feet
– South Santee River, South Carolina, to Cape Fear, North Carolina: 4 to 6 feet
– Ocracoke Inlet, North Carolina, to Salvo, North Carolina: 4 to 6 feet
– Salvo, North Carolina, to the North Carolina/Virginia border: 2 to 4 feet
– Edisto Beach, South Carolina, to the South Santee River, South Carolina: 2 to 4 feet
These water levels will be on top of already high tides caused by the new moon.
The National Weather Service is forecasting a record tide level at Beaufort, North Carolina, overnight tonight, topping levels seen during Hazel (1954) and Floyd (1999), among others.
Battering waves will ride atop the storm surge, inflicting more damage to structures near the water as the hurricane arrives.
Tidal flooding will also occur with high tide as far north as the southern Chesapeake Bay, including along the tidal James River and Potomac River near the bay.
– High-Impact Rainfall: Florence will produce high-end flash flooding between Myrtle Beach, South Carolina, and Morehead City, North Carolina.
The National Hurricane Center noted that “life-threatening, catastrophic flash flooding and prolonged significant river flooding are likely over portions of the Carolinas and the southern and central Appalachians late this week into early next week.”
That heavy rain threat may last for days into early next week in some areas, given Florence’s slow movement.
Disastrous flooding is expected in some areas, not simply near the coastal Carolinas where the heaviest rain totals are forecast, but also in the Appalachians where heavy rain over mountainous terrain is likely to trigger mudslides and rockslides. See the link below for more information.
According to the National Hurricane Center, Florence is expected to produce the following rainfall totals:
– Coastal North Carolina into far northeastern South Carolina: 20 to 30 inches, with isolated totals up to 40 inches
– Rest of South Carolina and North Carolina into southwestern Virginia: 6 to 12 inches, with isolated totals up to 15 inches
The runoff from these incredible rainfall totals will continue for days, and then will enter the riverways of the Carolinas. Flooding may swell these watersheds for weeks, if not months.
– Wind Impact: Tropical-storm-force winds (39-plus mph) are already occurring along parts of the coast of the Carolinas. Hurricane-force winds (74-plus mph) are expected to arrive later this evening or early Friday. Numerous downed trees and long-lasting power outages could occur near and inland from where the center of Florence strikes.
This threat of tree damage and power outages may also extend across Florence’s larger swath of tropical-storm-force winds and may last for an extended period of time into this weekend. Structural damage to homes and buildings is possible, particularly where the core of any hurricane-force winds moves through.
– Tornadoes: A few tornadoes are possible in eastern and southeastern North Carolina through Friday. These tornadoes should be weak and short-lived but could add to damage caused by rainfall or straight-line hurricane winds.

Tropical Depression Six formed late on Aug. 31, then was named Tropical Storm Florence the next day in the far eastern Atlantic Ocean.
On Sept. 5, Florence became a Category 4 hurricane after rapidly intensifying over the open Atlantic Ocean.
Wind shear then weakened Florence back to a tropical storm late on Sept. 6.
Florence underwent rapid intensification a second time Sunday into Monday, when its winds jumped up from 75 mph to 130 mph in just 25 hours ending 12 p.m. EDT Monday.
