Posting Date: September 12, 2018, 1:30:00 PM

As of 11 a.m. EDT on Sept. 12, Hurricane Florence was located about 485 miles (785 km) southeast of Wilmington, North Carolina, and about 520 miles (840 km) east-southeast of Myrtle Beach, South Carolina, at latitude 29.8°N, longitude 71.3°W, with maximum sustained winds of 130 mph (215 km/h) and a central pressure of 943 mb. Florence is moving northwest at 15 mph (28 km/h).

Hurricane Florence is currently a Category 4 storm and is forecast to remain at Category 4 intensity for the next 36 hours as it approaches the U.S. coastline. By the morning of Friday, September 14, Florence is expected to slow significantly. Florence is forecast to weaken to a Category 2 storm after drifting westward just offshore until Saturday morning, when it is expected to make landfall near the border between North Carolina and South Carolina.

Storm surge heights are expected to be as high as 9 to 13 feet, and Florence’s slow motion just offshore will mean several high tide cycles could occur as Florence is making landfall, exacerbating the storm surge hazard threat. After making landfall, Florence’s continued slow motion is expected to bring it west across North Carolina or South Carolina. In addition, the slow motion is expected to produce severe inland flooding from rainfall amounts that could total as much as 20 to 30 inches, with some local areas forecast to receive up to 40 inches across South Carolina and western and northern North Carolina.
